Description
Technical Field
[0001] This utility model relates to the technical field of precision parts processing equipment, specifically to a stable structure for a slow wire EDM machine tool. Background Technology
[0002] Wire EDM machines, as key process testing instruments in the fields of electronics and communication technology, operate on the principle of using a continuously moving fine metal wire (usually copper or molybdenum) as an electrode. This wire discharges through pulses, generating temperatures exceeding 6000°C to remove metal and cut the workpiece. They are widely used in CNC machining of high-precision workpieces. In practical applications, stable workpiece clamping is crucial for ensuring cutting accuracy. Workpiece displacement during cutting directly leads to positional deviations, affecting not only workpiece quality but also potential electrode wire wear and reduced processing efficiency. Therefore, a stable structure is a vital component of wire EDM machines, and its performance directly determines the machine's reliability.
[0003] Chinese patent CN220943556U discloses a stabilizing structure for a slow wire EDM machine. This structure includes a support base plate, a tilting mechanism, and a clamping mechanism. The clamping mechanism consists of a cutting plate, a U-shaped plate, a square groove, a limiting rod, and a threaded rod. The threaded rod drives two U-shaped plates to move along the square groove, using the inner walls of the U-shaped plates to clamp and fix the workpiece, preventing displacement during cutting. However, this existing stabilizing structure still has significant technical defects: its clamping mechanism relies solely on the inner plane of the U-shaped plate to contact the workpiece, and is only suitable for regular-shaped workpieces (such as rectangular or square). For irregular-shaped workpieces such as round or irregularly shaped workpieces, the inner wall of the U-shaped plate cannot effectively fit the workpiece surface, resulting in uneven clamping force distribution. The workpiece is prone to loosening or deformation due to excessive local stress, which not only reduces clamping stability but also seriously affects the cutting accuracy of irregularly shaped workpieces. Furthermore, this defect limits the applicability of existing stable structures, making it unable to meet the processing needs of diverse workpieces and reducing the overall practicality and adaptability of slow wire EDM machines. Utility Model Content
[0004] The purpose of this invention is to provide a stable structure for a slow wire EDM machine tool that has a wide range of applications, good clamping stability, more convenient operation, and better protection of the workpiece surface.
[0005] This utility model is achieved through the following technical solution: a stable structure for a slow wire EDM cutting machine, comprising: a cutting plate; the cutting plate has a first opening extending through both sides along its length, and a sliding groove is formed on the inner wall of each of the two first openings along the length of the cutting plate, with the two sliding grooves in the same first opening being symmetrically distributed; two sets of clamping assemblies, the two sets of clamping assemblies being symmetrically arranged at both ends of the cutting plate, and each set of clamping assemblies being slidably connected to the cutting plate; each set of clamping assemblies includes a U-shaped clamping plate, a second opening, a connecting plate, several reserved mounting holes, a mounting rod, and an arc-shaped clamping plate; the opening of the U-shaped clamping plate faces the center of the cutting plate, and the second opening extends through the side wall of the U-shaped clamping plate facing the center of the cutting plate; the connecting plate is vertically fixedly connected to the side of the U-shaped clamping plate away from the center of the cutting plate. The connecting plate has an outer side wall, and the length direction of the connecting plate is consistent with the height direction of the U-shaped clamp. Several pre-reserved mounting holes are evenly spaced on the connecting plate along its length. One end of the mounting rod is vertically fixedly connected to the outer side wall of the arc-shaped clamp, and the arc-shaped clamp is adapted to be embedded in the second opening, with the inner side wall of the arc-shaped clamp protruding from the inner side wall of the U-shaped clamp. The other end of the mounting rod passes through the second opening and extends to one side of the connecting plate, and a pre-reserved connecting hole is provided at this end of the mounting rod. The pre-reserved connecting hole can be coaxially aligned with any pre-reserved mounting hole, and the mounting rod and the connecting plate are detachably fixedly connected by bolts and nuts. There are also two sets of locking components, each set of locking components corresponding to one set of clamping components, and each set of locking components is used to lock and fix the position of the corresponding clamping component.
[0006] The working principle of this technical solution is as follows: a cutting plate provides a workpiece bearing base, two sets of symmetrically distributed clamping components are used to adapt and clamp workpieces of different shapes, and a locking component is used to fix the position of the clamping components to prevent workpiece displacement during the cutting process. Specifically, the U-shaped clamping plate is suitable for regular-shaped workpieces, while the arc-shaped clamping plate, through a detachable connection structure (mounting rod, connecting plate, bolts and nuts), is suitable for round and irregular-shaped workpieces. The sliding groove provides guidance for the sliding of the clamping components, ensuring smooth and precise clamping action.
[0007] To better realize this utility model, the two sets of clamping components further include vertical rods, sliders, fixing plates, racks, gears, and motors respectively; a vertical rod is vertically fixedly connected to both sides of the U-shaped clamping plate along the width direction of the cutting plate, and the two vertical rods correspond one-to-one with the first openings on both sides of the cutting plate; the lower end of the vertical rod passes through the corresponding first opening and extends to the bottom of the cutting plate, and sliders are fixedly connected to both sides of the vertical rod located in the first opening; the sliders correspond one-to-one with the sliding grooves on the inner wall of the first opening and slide in fit, realizing the sliding connection between the vertical rod and the cutting plate; the fixing plate is vertically fixedly connected to the outer wall of one of the vertical rods, and the length direction of the fixing plate is perpendicular to the length direction of the vertical rod; the rack is fixedly connected to the lower surface of the fixing plate along the length direction of the cutting plate; the motor body is fixedly installed, and the output shaft of the motor is horizontally installed along the width direction of the cutting plate; the gear is coaxially fixedly connected to the output shaft of the motor, and the gear meshes with the rack to drive the vertical rod to move the U-shaped clamping plate along the length direction of the cutting plate.
[0008] To better realize this utility model, further, after the lower end of the vertical rod passes through the first opening, the sliders on both sides of the vertical rod are respectively embedded in the corresponding grooves on the inner wall of the first opening, and the outer wall of the slider is in contact with the inner wall of the groove, so that the slider can slide smoothly along the length direction of the groove, thereby driving the vertical rod and the U-shaped clamp to move linearly along the length direction of the cutting plate.
[0009] To better realize this utility model, the two sets of locking components each include a bracket, an electric telescopic rod, a mounting plate, and a locking sleeve; the bracket is fixedly installed below the cutting plate, and the bracket is located on the side of the gear away from the rack; the cylinder of the electric telescopic rod is fixedly connected to the side of the bracket away from the gear, and the telescopic shaft of the electric telescopic rod is horizontally arranged along the width direction of the cutting plate and extends towards the gear; the mounting plate is vertically fixedly connected to the end of the telescopic shaft of the electric telescopic rod; the locking sleeve is fixedly connected to the side of the mounting plate facing the gear, and the inner wall of the locking sleeve has internal teeth adapted to the external teeth of the gear; when the telescopic shaft of the electric telescopic rod extends, the locking sleeve can be fitted onto the outside of the gear, and the internal teeth of the locking sleeve mesh with the external teeth of the gear to lock the gear; when the telescopic shaft of the electric telescopic rod retracts, the locking sleeve separates from the gear, releasing the lock.
[0010] To better realize this utility model, it further includes a fixed base, a square sleeve, a support plate, a support, and a rotating plate; the fixed base is a rectangular block structure and is fixedly installed below the cutting plate; the lower end of the support is fixedly connected to the upper surface of the fixed base; the square sleeve is a rectangular frame structure with openings at both ends, the square sleeve is fitted and fixedly connected to the outer wall of the support plate, and the length direction of the square sleeve is consistent with the length direction of the support plate; there are two fixed bases, and the two fixed bases are respectively vertically fixedly connected to the outer walls of the square sleeve along the length direction; the support plate is horizontally installed, and the upper surface of the support plate is fixedly connected to the lower surface of the cutting plate by bolts; there are two supports, and the two supports are respectively vertically fixedly connected to the two ends of the lower surface of the support plate along the length direction; the rotating plate is horizontally installed below the support plate, and the lower ends of the two supports are rotatably connected to the upper surface of the rotating plate through a rotating shaft, so that the support plate can drive the cutting plate to rotate around the rotating shaft.
[0011] To better realize this utility model, the motor body is further fixedly connected to the upper surface of the fixed base by bolts, and the output shaft of the motor extends away from the square sleeve, so that the gear and rack are kept in a meshing state.
[0012] To better realize this utility model, the rotating plate is further provided with an angle positioning component, which includes a positioning bolt and an arc-shaped positioning hole. The arc-shaped positioning hole is opened on the rotating plate with the rotating shaft connecting the support and the rotating plate as the center and is located on the outside of the support. The screw end of the positioning bolt passes through the arc-shaped positioning hole and is threadedly connected to the side wall of the support. The nut end of the positioning bolt is in contact with the lower surface of the rotating plate. When the support plate drives the cutting plate to rotate around the rotating shaft to the target angle, tightening the positioning bolt can fix the support and the rotating plate relative to each other, thereby locking the rotation angle of the cutting plate.
[0013] To better realize this utility model, the inner walls of the U-shaped clamp and the inner walls of the arc-shaped clamp are further fitted with elastic anti-slip pads. The elastic anti-slip pads are made of nitrile rubber, and the inner walls of the elastic anti-slip pads are provided with diamond-shaped anti-slip patterns. The thickness of the elastic anti-slip pads is 1-3mm. When the U-shaped clamp or the arc-shaped clamp clamps the workpiece, the elastic anti-slip pads can fit tightly against the outer wall of the workpiece, compensate for the small irregular protrusions on the outer wall of the workpiece through elastic deformation, and increase the friction with the workpiece through the anti-slip patterns.
[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: (1) This utility model constructs a detachable irregular workpiece adaptation structure by opening a second opening on the U-shaped clamping plate of the clamping assembly, fixing a connecting plate on one side of the U-shaped clamping plate, and setting an installation rod with a reserved connection hole and an arc-shaped clamping plate. When processing regular-shaped workpieces, the inner wall of the U-shaped clamping plate can be used for clamping; when processing round or irregular irregular workpieces, the arc-shaped clamping plate can be inserted into the second opening through the installation rod, and aligned with any reserved installation hole on the connecting plate through the reserved connection hole and fixed with bolts. The arc-shaped inner wall of the arc-shaped clamping plate can then be used to fit against the workpiece surface to achieve effective clamping. This breaks the limitation of existing structures that are only adapted to regular workpieces, and enables the stable structure to flexibly adapt to workpieces of various shapes such as regular and irregular shapes, significantly expanding the scope of application and improving the machine tool's adaptability to diverse processing needs. (2) The present invention adds a vertical rod, a slider, a rack, a gear and a motor to the clamping assembly. The motor drives the gear to rotate, and the gear meshes with the rack to drive the vertical rod to move along the first opening of the cutting plate. At the same time, the sliders on both sides of the vertical rod slide with the grooves on the inner wall of the first opening to provide precise guidance for the movement of the vertical rod, avoid the U-shaped clamping plate from shifting during the clamping process, and ensure that the clamping position is accurate and controllable. (3) In this utility model, the locking component is fixed by the bracket to the electric telescopic rod. The electric telescopic rod drives the mounting plate and the locking sleeve to move. When the clamping component is adjusted to the position, the locking sleeve can be fitted to the outside of the gear and locked by the internal gear meshing. This effectively prevents the clamping component from shifting due to the slippage of the gear thread, further ensuring the stability of the workpiece during the cutting process and avoiding cutting deviation caused by clamping looseness. (4) This utility model adopts a modular design with clear connection between each component, which not only facilitates factory production and assembly, but also enables individual replacement when parts are worn out, reducing maintenance costs and difficulties. The support under the support plate is connected to the rotating shaft of the rotating plate, so that the cutting plate can be rotated around the rotating shaft to adjust the angle. Not only can the workpiece processing angle be flexibly adjusted according to the cutting process requirements to adapt to different cutting paths, but also the metal chips generated during the cutting process can slide naturally along the inclined cutting plate surface, reducing the accumulation of chips on the cutting plate surface, reducing the interference of chips on the cutting accuracy, and reducing the amount of manual cleaning work, thus improving processing efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:
[0020] The main structure of this embodiment is as follows: Figures 1-3 As shown, it includes: Cutting plate 1; The cutting plate 1 has a first opening 101 through both sides along the length direction, and a sliding groove 102 is formed on the inner wall of the two first openings 101 along the length direction of the cutting plate 1, and the two sliding grooves 102 in the same first opening 101 are symmetrically distributed. Two sets of clamping components 2 are symmetrically arranged at both ends of the cutting plate 1, and each set of clamping components 2 is slidably connected to the cutting plate 1. Each set of clamping components 2 includes a U-shaped clamping plate 201, a second opening 208, a connecting plate 209, several reserved mounting holes 210, a mounting rod 211, and an arc-shaped clamping plate 212. The opening of the U-shaped clamping plate 201 faces the center of the cutting plate 1, and the second opening 208 is formed through the side wall of the U-shaped clamping plate 201 facing the center of the cutting plate 1. The connecting plate 209 is vertically fixed to the outside of the side wall of the U-shaped clamping plate 201 away from the center of the cutting plate 1, and the length direction of the connecting plate 209 is consistent with the height direction of the U-shaped clamping plate 201. A plurality of the reserved mounting holes 210 are evenly spaced along the length of the connecting plate 209; one end of the mounting rod 211 is perpendicularly fixedly connected to the outer side wall of the arc-shaped clamp 212, the arc-shaped clamp 212 is adapted to be embedded in the second opening 208, and the inner side wall of the arc-shaped clamp 212 protrudes from the inner side wall of the U-shaped clamp 201; the other end of the mounting rod 211 passes through the second opening 208 and extends to one side of the connecting plate 209, and a reserved connecting hole is provided at this end of the mounting rod 211; the reserved connecting hole can be coaxially aligned with any one of the reserved mounting holes 210, and the mounting rod 211 and the connecting plate 209 are detachably fixedly connected by the cooperation of bolts and nuts; And two sets of locking components 3, each set of locking components 3 is respectively set in correspondence with two sets of clamping components 2, and each set of locking components 3 can be locked and fixed by the position of the corresponding clamping component 2.
[0021] The specific implementation process is as follows: A first opening 101 is machined through both sides of the cutting plate 1 along its length. A symmetrically distributed sliding groove 102 is machined on the inner wall of each first opening 101 along the length of the cutting plate 1. Two sets of clamping components 2 are symmetrically installed at both ends of the cutting plate 1, so that the clamping components 2 and the cutting plate 1 form a sliding connection. Two sets of locking components 3 are assembled one-to-one with the two sets of clamping components 2 to ensure that the locking components 3 can act on the clamping components 2.
[0022] With the opening of the U-shaped clamp 201 facing the center of the cutting plate 1, a second opening 208 is machined through the side wall of the U-shaped clamp 201 facing the center of the cutting plate 1; the connecting plate 209 is vertically fixed to the outside of the side wall of the U-shaped clamp 201 away from the center of the cutting plate 1, ensuring that the length direction of the connecting plate 209 is consistent with the height direction of the U-shaped clamp 201, and several pre-reserved mounting holes 210 are machined evenly at intervals along the length direction of the connecting plate 209; one end of the mounting rod 211 is vertically fixed to the outer wall of the arc-shaped clamp 212, and the arc-shaped clamp 212 is fitted into the second opening 208, ensuring that the inner side wall of the arc-shaped clamp 212 protrudes beyond the U-shaped clamp. The inner wall of plate 201; the other end of the mounting rod 211 extends through the second opening 208 to one side of the connecting plate 209, and a pre-drilled connection hole is machined at this end; depending on the shape of the workpiece, whether to install the arc-shaped clamping plate 212 is selected. If it is a round or irregularly shaped workpiece, adjust the position of the mounting rod 211 so that the pre-drilled connection hole is coaxially aligned with the appropriate pre-drilled mounting hole 210 on the connecting plate 209. Use bolts to pass through the pre-drilled connection hole and the pre-drilled mounting hole 210, and then use nuts to detachably fix the mounting rod 211 to the connecting plate 209; if it is a regular shaped workpiece, the arc-shaped clamping plate 212 can be removed, and the U-shaped clamping plate 201 can be used directly for clamping.
[0023] After confirming that both sets of locking components 3 are in a ready-to-work state, and ensuring that the clamping components 2 are adjusted in place, their positions can be locked and fixed by the locking components 3. Example 2:
[0024] This embodiment further defines the structure of the clamping assembly 2 based on the above embodiment, such as... Figure 3As shown, the two sets of clamping assemblies 2 also include vertical rods 202, sliders 203, fixing plates 204, racks 205, gears 206, and motors 207, respectively; a vertical rod 202 is vertically fixedly connected to both sides of the U-shaped clamping plate 201 along the width direction of the cutting plate 1, and the two vertical rods 202 correspond one-to-one with the first openings 101 on both sides of the cutting plate 1; the lower end of the vertical rod 202 passes through the corresponding first opening 101 and extends to the bottom of the cutting plate 1, and sliders 203 are fixedly connected to both sides of the vertical rod 202 located in the first opening 101; the sliders 203 correspond one-to-one with the sliding grooves 102 on the inner wall of the first opening 101 and slide together. The vertical rod 202 and the cutting plate 1 are slidably connected; the fixing plate 204 is vertically fixed to the outer wall of one of the vertical rods 202, and the length direction of the fixing plate 204 is perpendicular to the length direction of the vertical rod 202; the rack 205 is fixedly connected to the lower surface of the fixing plate 204 along the length direction of the cutting plate 1; the motor 207 is fixedly mounted on the body, and the output shaft of the motor 207 is horizontally mounted along the width direction of the cutting plate 1; the gear 206 is coaxially fixedly connected to the output shaft of the motor 207, and the gear 206 meshes with the rack 205 to drive the vertical rod 202 to move the U-shaped clamping plate 201 along the length direction of the cutting plate 1. By supplementing the vertical rod 202, the slider 203, the fixing plate 204, the rack 205, the gear 206, and the motor 207, an electrically driven clamping and adjusting structure is constructed. Power is output from motor 207 and transmitted through gear 206 and rack 205, converting the rotational motion of motor 207 into linear motion of rack 205. This, in turn, drives vertical rod 202 and U-shaped clamping plate 201 to move along the length of cutting plate 1, achieving precise electric adjustment of clamping force and position. Sliding block 203 and sliding groove 102 provide guidance for the movement of vertical rod 202, preventing deviation during movement and ensuring clamping stability.
[0025] The specific implementation process is as follows: To supplement the clamping assembly 2, a vertical rod 202 is vertically fixed on each side of the U-shaped clamping plate 201 along the width direction of the cutting plate 1, so that the two vertical rods 202 correspond one-to-one with the first openings 101 on both sides of the cutting plate 1; the lower ends of the vertical rods 202 are extended through the corresponding first openings 101 to the bottom of the cutting plate 1, and a slider 203 is fixed on each side of the vertical rods 202 located in the first openings 101, so that the sliders 203 correspond one-to-one with the sliding grooves 102 on the inner wall of the first openings 101 and form a sliding fit. The fixing plate 204 is vertically fixed to the outer wall of one of the vertical rods 202, ensuring that the length direction of the fixing plate 204 is perpendicular to the length direction of the vertical rod 202; the rack 205 is fixed to the lower surface of the fixing plate 204 along the length direction of the cutting plate 1; the motor 207 body is fixedly set so that the output shaft of the motor 207 is set horizontally along the width direction of the cutting plate 1; the gear 206 is coaxially fixed on the output shaft of the motor 207, and the position of the motor 207 is adjusted so that the gear 206 and the rack 205 mesh precisely.
[0026] Start motor 207. The output shaft of motor 207 drives gear 206 to rotate. Gear 206 meshes with rack 205, driving rack 205 to move along the length of cutting plate 1. Rack 205 drives fixed plate 204, vertical rod 202, and U-shaped clamp 201 to move synchronously. Test whether the movement of U-shaped clamp 201 is smooth and stable. If there is any jamming, check the fit between slider 203 and slide groove 102 and the meshing of gear 206 and rack 205 until it is smooth. Other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 3:
[0027] This embodiment further defines the structure of the clamping assembly 2 based on the above embodiment, such as... Figure 3 As shown, after the lower end of the vertical rod 202 passes through the first opening 101, the sliders 203 on both sides of the vertical rod 202 are respectively embedded in the corresponding grooves 102 on the inner wall of the first opening 101, and the outer wall of the slider 203 is in contact with the inner wall of the groove 102, so that the slider 203 can slide smoothly along the length direction of the groove 102, thereby driving the vertical rod 202 and the U-shaped clamping plate 201 to move linearly along the length direction of the cutting plate 1. To further optimize the fitting accuracy between the slider 203 and the groove 102, by making the outer wall of the slider 203 fit tightly with the inner wall of the groove 102, the gap between the two is reduced, avoiding wobbling during the movement of the vertical rod 202, ensuring that the vertical rod 202 drives the U-shaped clamping plate 201 to move linearly along the length direction of the cutting plate 1, improving the accuracy of the clamping position, and providing a guarantee for the subsequent workpiece cutting accuracy.
[0028] The specific implementation process is as follows: After the lower end of the vertical rod 202 passes through the first opening 101, check whether the sliders 203 on both sides of the vertical rod 202 are accurately embedded in the corresponding grooves 102 on the inner wall of the first opening 101. If there is a gap between the outer wall of the slider 203 and the inner wall of the groove 102, grind the outer wall of the slider 203 or the inner wall of the groove 102 to make the outer wall of the slider 203 fit tightly with the inner wall of the groove 102; if the gap is too large, replace the slider 203 with one of the appropriate size to ensure that the slider 203 can slide smoothly in the groove 102 without obvious shaking.
[0029] Start motor 207, drive vertical rod 202 to move U-shaped clamp 201 along the length of cutting plate 1. Use a ruler or laser positioning instrument to check whether the movement trajectory of U-shaped clamp 201 is a straight line. If there is a deviation, further adjust the cooperation between slider 203 and slide groove 102 until U-shaped clamp 201 achieves smooth straight movement. Other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 4:
[0030] This embodiment further defines the structure of the locking component 3 based on the above embodiments, such as... Figure 4 As shown, the two sets of locking components 3 each include a bracket 301, an electric telescopic rod 302, a mounting plate 303, and a locking sleeve 304. The bracket 301 is fixedly installed below the cutting plate 1, and the bracket 301 is located on the side of the gear 206 away from the rack 205. The cylinder of the electric telescopic rod 302 is fixedly connected to the side of the bracket 301 away from the gear 206, and the telescopic shaft of the electric telescopic rod 302 is horizontally arranged along the width direction of the cutting plate 1 and extends towards the gear 206. The mounting plate 303 is vertically fixedly connected to the electric telescopic rod 304. The telescopic rod 302 has a telescopic shaft at its end; the locking sleeve 304 is fixedly connected to the mounting plate 303 on the side facing the gear 206, and the inner wall of the locking sleeve 304 has internal teeth that are adapted to the external teeth of the gear 206; when the telescopic shaft of the electric telescopic rod 302 extends, the locking sleeve 304 can be sleeved on the outside of the gear 206, and the internal teeth of the locking sleeve 304 mesh with the external teeth of the gear 206 to lock the gear 206; when the telescopic shaft of the electric telescopic rod 302 retracts, the locking sleeve 304 separates from the gear 206, releasing the lock. The bracket 301 provides fixed support for the electric telescopic rod 302, and the electric telescopic rod 302 drives the mounting plate 303 and the locking sleeve 304 to move. The internal teeth structure of the inner wall of the locking sleeve 304 that are adapted to the external teeth of the gear 206 realizes the meshing or separation of the locking sleeve 304 and the gear 206. When engaged, gear 206 cannot rotate, thus fixing the positions of rack 205, vertical rod 202 and U-shaped clamp 201; when disengaged, gear 206 can rotate normally, making it easy to adjust the clamping position.
[0031] The specific implementation process is as follows: Assemble the locking assembly 3. Fix the bracket 301 below the cutting plate 1, ensuring that the bracket 301 is located on the side of the gear 206 away from the rack 205, reserving space for the subsequent movement of the locking sleeve 304. Fix the cylinder of the electric telescopic rod 302 to the side of the bracket 301 away from the gear 206, so that the telescopic shaft of the electric telescopic rod 302 is horizontally positioned along the width direction of the cutting plate 1 and extends towards the gear 206; fix the mounting plate 303 vertically to the end of the telescopic shaft of the electric telescopic rod 302. Machine internal teeth that match the external teeth of the gear 206 on the inner wall of the locking sleeve 304. Fix the locking sleeve 304 to the side of the mounting plate 303 facing the gear 206. Adjust the position of the locking sleeve 304 to ensure that when the telescopic shaft of the electric telescopic rod 302 extends, the locking sleeve 304 can be accurately fitted onto the outside of the gear 206.
[0032] Start the electric telescopic rod 302 to extend the telescopic shaft. Observe whether the locking sleeve 304 engages with the gear 206. If the gear 206 cannot rotate after engagement, the locking function is normal. Control the telescopic shaft of the electric telescopic rod 302 to retract and observe whether the locking sleeve 304 disengages from the gear 206. If the gear 206 can rotate normally after disengagement, the unlocking function is normal. If locking or unlocking is not smooth, adjust the installation position of the electric telescopic rod 302 or the angle of the locking sleeve 304 until the function is normal. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 5:
[0033] This embodiment, based on the above embodiment, further adds a fixed base 4, a square sleeve 5, a support plate 6, a support 7, and a rotating plate 8, as follows: Figure 1 , Figure 2As shown; the fixing seat 4 is a rectangular block structure and is fixedly installed below the cutting plate 1; the lower end of the bracket 301 is fixedly connected to the upper surface of the fixing seat 4; the square sleeve 5 is a rectangular frame structure with openings at both ends, the square sleeve 5 is fitted and fixedly connected to the outer wall of the support plate 6, and the length direction of the square sleeve 5 is consistent with the length direction of the support plate 6; there are two fixing seats 4, and the two fixing seats 4 are respectively vertically fixedly connected to the two outer walls of the square sleeve 5 along the length direction; the support plate 6 is horizontally installed, and the upper surface of the support plate 6 is fixedly connected to the lower surface of the cutting plate 1 by bolts; there are two supports 7, and the two supports 7 are respectively vertically fixedly connected to the two ends of the lower surface of the support plate 6 along the length direction; the rotating plate 8 is horizontally installed below the support plate 6, and the lower ends of the two supports 7 are rotatably connected to the upper surface of the rotating plate 8 through a rotating shaft, so that the support plate 6 can drive the cutting plate 1 to rotate around the rotating shaft. The fixed base 4 provides a stable installation foundation for the bracket 301 and the motor 207; the square sleeve 5 cooperates with the support plate 6 to realize the connection and fixation between the fixed base 4 and the support plate 6; the support plate 6 serves as an intermediate load-bearing component, connecting the cutting plate 1 and the support 7; the support 7 and the rotating plate 8 are rotatably connected by a rotating shaft, so that the support plate 6 can drive the cutting plate 1 to rotate around the rotating shaft, which is convenient for adjusting the workpiece cutting angle and adapting to different cutting needs, while also facilitating the sliding of cutting debris along the inclined cutting plate 1.
[0034] The specific implementation process is as follows: The fixing seat 4 is fixedly set below the cutting plate 1, and the lower end of the bracket 301 is fixed to the upper surface of the fixing seat 4; a rectangular frame structure with openings at both ends is processed as a square sleeve 5, and the square sleeve 5 is fitted and fixed to the outer wall of the support plate 6, ensuring that the length direction of the square sleeve 5 is consistent with the length direction of the support plate 6; the two fixing seats 4 are respectively vertically fixed to the outer walls of the square sleeve 5 on both sides along the length direction; the support plate 6 is set horizontally, and the upper surface of the support plate 6 is fixedly connected to the lower surface of the cutting plate 1 by bolts.
[0035] A support 7 is vertically fixed at each end of the lower surface of the support plate 6 along the length direction. The rotating plate 8 is horizontally set below the support plate 6. The lower ends of the two supports 7 are rotatably connected to the upper surface of the rotating plate 8 through the rotating shaft to ensure that the rotating shaft is firmly installed. The support plate 6 can be flexibly rotated around the rotating shaft.
[0036] Push the support plate 6 and observe whether it drives the cutting plate 1 to rotate smoothly around the axis. If there is any jamming during the rotation, check the fit between the axis, the support 7, and the rotating plate 8. Add lubricating oil or adjust the position of the axis until the rotation is smooth. At the same time, check whether the connections of each component are secure during the rotation to avoid loosening. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 6:
[0037] This embodiment, based on the above embodiment, further defines the connection relationship between the clamping assembly 2 and the fixing base 4, such as... Figure 3 As shown, the motor 207 is vertically fixed to the upper surface of the mounting base 4 by bolts, and the output shaft of the motor 207 extends away from the square sleeve 5, so that the gear 206 and the rack 205 remain in a meshing state. Clearly defining the connection method between the motor 207 and the mounting base 4, and the direction of the motor 207's output shaft, ensures stable installation of the motor 207 and that the gear 206 and rack 205 always maintain a reliable meshing state. The bolt fixing method enhances the stability of the motor 207 installation and prevents vibration of the motor 207 during cutting from causing misalignment of the gear 206 and rack 205. Limiting the output shaft's extension away from the square sleeve 5 prevents the square sleeve 5 from interfering with the transmission of the gear 206 and rack 205.
[0038] The specific implementation process is as follows: The motor 207 body is vertically fixed to the upper surface of the mounting base 4 with bolts, ensuring that the bolts are tightened and the motor 207 is not loose. Adjust the installation angle of the motor 207 so that the output shaft of the motor 207 extends away from the square sleeve 5. At the same time, observe the meshing of the gear 206 and the rack 205 to ensure that the two always maintain precise meshing without misalignment or disengagement.
[0039] Start motor 207 to drive gear 206 and rack 205. Observe whether motor 207 vibrates or deviates during operation. If deviation occurs, check the tightness of the bolts and retighten or replace them with larger bolts. At the same time, check whether the meshing of gear 206 and rack 205 is stable. If the meshing is poor, fine-tune the position of motor 207 until the transmission is stable. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 7:
[0040] This embodiment, based on the above embodiment, further adds an angle positioning component. The rotating plate 8 is also equipped with an angle positioning component, which includes a positioning bolt and an arc-shaped positioning hole. The arc-shaped positioning hole is centered on the rotating shaft connecting the support 7 and the rotating plate 8, and is located on the rotating plate 8 and outside the support 7. The screw end of the positioning bolt passes through the arc-shaped positioning hole and is threadedly connected to the side wall of the support 7, while the nut end of the positioning bolt is in contact with the lower surface of the rotating plate 8. Adding the angle positioning component solves the problem of the angle not being fixed after the cutting plate 1 is flipped. The arc-shaped positioning hole, centered on the rotating shaft, ensures that the positioning bolt can move along an arc-shaped trajectory, adapting to different flipping angles of the cutting plate 1. By threading the positioning bolt through the arc-shaped positioning hole to the support 7, after tightening the positioning bolt, the friction between the bolt nut and the rotating plate 8, and the threaded locking force between the bolt and the support 7, fix the support 7 and the rotating plate 8 relative to each other, thereby locking the flipping angle of the cutting plate 1 and ensuring angle stability during the cutting process.
[0041] The specific implementation process is as follows: With the rotating shaft connecting the support 7 and the rotating plate 8 as the center, an arc-shaped positioning hole is machined on the rotating plate 8 and located outside the support 7; a suitable positioning bolt is prepared, and the screw end of the positioning bolt is threaded through the arc-shaped positioning hole and connected to the side wall of the support 7, so that the nut end of the positioning bolt is in contact with the lower surface of the rotating plate 8.
[0042] Pushing the support plate 6 causes the cutting plate 1 to rotate around the axis to a target angle. At this time, the positioning bolt moves along the arc-shaped positioning hole. Tighten the positioning bolt and check whether the cutting plate 1 is maintained at the target angle. If it cannot move, it means that the angle locking function is normal. Loosen the positioning bolt and push the cutting plate 1 to rotate again. Check whether the positioning bolt can move smoothly along the arc-shaped positioning hole. If it moves smoothly, it means that the angle adjustment function is not affected. If the locking is not firm, check the thread fit between the positioning bolt and the support 7, or replace it with a nut with greater friction. If the movement is stuck, grind the inner wall of the arc-shaped positioning hole until the function is normal. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 8:
[0043] This embodiment, based on the above embodiment, further adds an elastic anti-slip pad. The inner walls of the U-shaped clamp 201 and the arc-shaped clamp 212 are both fitted with elastic anti-slip pads. The inner wall of the elastic anti-slip pad 11 has a diamond-shaped anti-slip texture. Adding the elastic anti-slip pad 11 to the inner walls of the U-shaped clamp 201 and the arc-shaped clamp 212 utilizes the elastic deformation characteristics of the elastic anti-slip pad 11 to compensate for minor irregular protrusions on the outer wall of the workpiece, making the clamp and workpiece fit more tightly. Simultaneously, the diamond-shaped anti-slip texture on the inner wall of the elastic anti-slip pad 11 increases the friction with the workpiece, preventing the workpiece from slipping due to vibration during cutting. This improves clamping stability and protects the workpiece surface from scratches by the clamp.
[0044] The specific implementation process is as follows: Prepare an elastic anti-slip mat 11 made of nitrile rubber, and process a diamond-shaped anti-slip pattern on the inner wall of the elastic anti-slip mat 11; attach and fix the elastic anti-slip mat 11 to the inner wall of the U-shaped clamp 201 and the inner wall of the arc-shaped clamp 212 respectively by means of glue or bolts, to ensure that the elastic anti-slip mat 11 is firmly fixed and there is no lifting or falling off.
[0045] Place the workpiece on the cutting plate 1, activate the clamping assembly 2 to clamp the workpiece with the U-shaped clamp 201 or the arc-shaped clamp 212, and observe whether the elastic anti-slip pad 11 is in close contact with the outer wall of the workpiece. If there is a gap, adjust the position of the clamping plate or replace the elastic anti-slip pad 11 with one of suitable thickness. Gently shake the workpiece to check for slippage. If slippage occurs, check whether the anti-slip texture of the elastic anti-slip pad 11 is clear, or increase the clamping force until the workpiece does not wobble significantly. After clamping for a period of time, remove the workpiece and check whether there are scratches on the workpiece surface. If there are scratches, adjust the clamping force or replace the elastic anti-slip pad 11 with one made of softer material to ensure that the workpiece surface is protected while the clamping is stable. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.
