Description

Technical Field

[0001] The present invention relates to the technical field of part processing, and specifically to a machine tool adaptive chuck structure for processing irregular parts. Background Technique

[0002] During the processing of mechanical parts, regular or irregular parts are placed on a machine tool for processing. A fixture for clamping the workpiece is usually provided on the machine tool, and a cutting tool is used to process the workpiece. When the machine tool clamps an irregular part, the clamping effect of the part during processing is often poor due to the low matching degree between the fixture and the part.

[0003] For example, in the patent document CN216462048U, an auxiliary fixture for processing irregular parts of a CNC milling machine uses a toggle rod to drive the movement of a chuck and a pressing plate, causing the spring to contract and the chuck to disengage from the card slot, realizing the operation of replacing the fixture according to the different shapes of the parts.

[0004] However, although the above patent content can be used for clamping irregular parts, it only clamps one end or a fixed height of the part placed on the placement table, and cannot make an adaptive clamping position adjustment for irregular parts. Compared with regular parts, the external area of irregular parts is tortuous and uneven, and it is more important to select important clamping positions. Moreover, the clamping distance of the fixture to the part is also an important factor affecting the clamping effect of irregular parts.

[0005] In view of the technical defects in this regard, a solution is now proposed. Summary of the Invention

[0006] The purpose of the present invention is not only to adaptively clamp and limit irregular and regular parts, reduce the situation of hard clamping damage or offset of the parts, improve the processing efficiency of irregular parts, but also adjust the clamping position or height of the fixture for irregular parts according to the processing requirements to increase the clamping effect on irregular parts.

[0007] The purpose of the present invention can be achieved by the following technical solutions: A machine tool adaptive chuck structure for processing irregular parts, including an operating table and a cover frame with an inverted concave structure. The cover frame is clamped at one end of the top surface of the operating table, and a material clamping mechanism is provided on the top of the cover frame.

[0008] Among them, the material clamping mechanism includes a chassis. The chassis is arranged on the top of the cover frame, and a first motor is arranged at the center of the bottom surface of the chassis. The output end of the first motor at the bottom is provided with a turntable, and a connecting rod fixedly installed at the center of the bottom of the turntable is rotatably connected to the top surface of the cover frame. A number of hinge rods are equally spaced and hinged to the bottom surface of the turntable. The top surface of the chassis is connected to a placement tray through an adjustment assembly.

[0009] Further, both the front and rear inner walls of the cover frame are rotatably connected to the front and rear inner walls of the operating table through rotatable rods fixedly installed at one end. The two groups of rotatable rods respectively extend outside the cover frame and are fixedly connected with limiting gears. An arcuate push frame is commonly sleeved outside the two groups of limiting gears.

[0010] Further, the arcuate push frame is sleeved outside the operating table. A cylinder is arranged on one side of the operating table away from the cover frame, and the cylinder is fixedly connected with the arcuate push frame through a push rod. Rectangular slots are respectively formed in the front and rear frames of the arcuate push frame and at one end of the cover frame, and a tooth slot group is arranged on the inner wall of the top of the rectangular slot. The limiting gear extends into the rectangular slot and meshes with the tooth slot group.

[0011] Further, a number of arcuate-shaped card frames are sleeved at equal intervals on the border of the storage tray. The thickness of the inner groove of the card frame is 4 times the thickness of the storage tray. A vertical rod is commonly hinged between the bottom of each group of card frames and the corresponding hinge rod. Each group of vertical rods respectively passes through the inside of a card slot arranged on the outer wall of the chassis.

[0012] Further, a sliding rod is fixedly installed at the center of the card frame near the open end. The sliding rod is slidably connected inside a sliding groove arranged on the top surface of the storage tray. Collar rings are movably sleeved at both the upper and lower ends of the sliding rod outside the sliding rod. A spring coil group is wound between the bottom collar ring outside the sliding rod and the inner wall of the bottom of the card frame. An elastic pressing component is arranged at the top surface of each group of card frames near the open end.

[0013] Further, the elastic pressing component includes two rectangular-shaped sliding frames. The two groups of sliding frames are respectively sleeved inside a long groove arranged on the top surface of the card frame. Damping spring shock-absorbing rings are respectively arranged between the sides of the two groups of sliding frames away from each other and the inner walls of the corresponding long grooves. A groove is formed at one end of the sliding frame extending outside the card frame. An inclined-shaped pressing rod is hinged inside the groove. The two groups of pressing rods are commonly hinged at one end away from the groove with an arcuate pressing frame, and the side of the arcuate pressing frame away from the open end is arranged in a curved surface structure.

[0014] Further, the adjusting component includes a second motor. The second motor is arranged at a position near one side of the center of the top surface of the chassis, and a driving gear is fixedly installed at the output end of the top of the second motor. A rotating cylinder is rotatably connected to the center of the top surface of the chassis, and a driven toothed ring is fixedly sleeved at the top opening of the rotating cylinder. The driving gear meshes with the driven toothed ring.

[0015] Further, a round shaft is fixedly installed at the center of the inner wall of the top of the rotating cylinder. A push cylinder penetrates and is connected to the opening of the rotating cylinder, and the top end of the push cylinder is fixedly connected to the bottom surface of the storage tray. A limiting inclined slot is arranged outside the push cylinder, and the round shaft is slidably connected to one end of the limiting inclined slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the present invention, a card material mechanism is provided. When the turntable rotates, a number of hinge rods rotate accordingly, and the corresponding card frames are pulled to move by the vertical rods. Multiple card frames move simultaneously towards the center of the placement tray. The concave-shaped abutting frame first contacts the side wall of the part. The concave-shaped abutting frame is abutted and respectively pushes two abutting rods in opposite directions. The abutting rods tilt and deflect respectively to push the corresponding sliding frames to move. Due to the excessive difference in the concavity and convexity of the part surface contacted by the concave-shaped abutting frame, the angles of the two abutting rods unidirectionally pushed by some concave-shaped abutting frames are inconsistent, which also results in inconsistent positions of the two sliding frames moving, so as to adapt to the clamping and limitation of the irregular surface of the irregular part and reduce the situation of the irregular part falling off;

[0018] Similarly, this clamping method is also applicable to the clamping of regular parts;

[0019] Then this structure is not only applicable to the clamping of irregular and regular parts, but also adapts to the multi-sided irregular surfaces of irregular parts for clamping, reduces damage caused by hard clamping of irregular parts, and improves the part processing efficiency.

[0020] 2. The present invention also cooperates by setting an adjustment component. The second motor drives the driving gear to rotate, and the driving gear meshes with the driven toothed ring to realize the self-rotation of the rotating cylinder. The round shaft rotates inside the limiting inclined groove and forces the pushing cylinder and the placement tray to be pulled downward. The bottom of the placement tray respectively presses a number of collar rings near the bottom, and the spring coil is compressed. The parts on the surface of the placement tray settle synchronously with the placement tray, forcing the distance between the elastic pressing component at the top of the card frame and the surface of the placement tray to increase. Thus, the position height of the multiple elastic pressing components pressing on the outside of the part changes accordingly. Then, according to the processing requirements, the clamping position or height of the irregular part by the fixture is adjusted to increase the clamping effect on the irregular part.

Specific embodiments

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0031] Embodiment 1: Please refer to Figure 1 - Figure 7 As shown in the figure, a self-adaptive chuck structure for a machine tool based on the processing of irregular parts includes an operating table 1 and a cover frame 2 with an inverted concave structure. The cover frame 2 is clamped at one end of the top surface of the operating table 1, and a card material mechanism 3 is provided on the top of the cover frame 2;

[0032] Among them, the card material mechanism 3 includes a chassis 31. The chassis 31 is arranged on the top of the cover frame 2, and a motor 1 32 is arranged at the center of the bottom surface of the chassis 31. The bottom output end of the motor 1 32 is provided with a turntable 33, and the connecting rod fixedly installed at the center of the bottom of the turntable 33 is rotatably connected to the top surface of the cover frame 2. A plurality of groups of hinge rods 34 are equally spaced and hinged to the bottom surface of the turntable 33. The top surface of the chassis 31 is connected to a storage tray 35 through an adjustment component 4;

[0033] A plurality of groups of concave-shaped card frames 36 are equally spaced and sleeved on the edge of the storage tray 35, and the thickness of the inner groove of the card frame 36 is 3-5 times the thickness of the storage tray 35. A vertical rod 37 is jointly hinged between the bottom of each group of card frames 36 and the corresponding hinge rod 34, and each group of vertical rods 37 respectively passes through the internal card slots provided on the outer wall of the chassis 31;

[0034] Place the irregular part to be processed at the center of the placement tray 35, start the motor 1 32 to drive the turntable 33 to rotate, and the multiple sets of hinge rods 34 rotate accordingly, and use the vertical rods 37 to pull the corresponding clamping frames 36 to move. Multiple sets of clamping frames 36 move toward the center of the placement tray 35 at the same time, and jointly clamp the irregular part in the center of the placement tray 35;

[0035] A slide rod 361 is fixedly installed at the center of the card frame 36 near the open end. The slide rod 361 is slidably connected to the inside of the slide groove provided on the top surface of the storage tray 35. An elastic pressing component 310 is provided on the top surface of each card frame 36 near the open end.

[0036] The elastic pressing assembly 310 includes two groups of sliding frames 311 with rectangular structures. The two groups of sliding frames 311 are respectively sleeved inside the long grooves set on the top surface of the card frame 36. Damping spring shock-absorbing rings 312 are respectively set between the side of the two groups of sliding frames 311 away from each other and the inner walls of the corresponding long grooves. The sliding frame 311 extends to the outside of the card frame 36 and is provided with a groove. An inclined supporting rod 313 is hinged inside the groove. The ends of the two groups of supporting rods 313 away from the groove are jointly hinged with a concave supporting frame 314, and the side of the concave supporting frame 314 away from the opening is arranged in a curved structure to reduce damage to the parts caused by hard clamping.

[0037] When clamping an irregular part, several groups of clamping frames 36 approach the part, and the concave supporting frames 314 first contact the side wall of the part. As the clamping frames 36 continue to press, the concave supporting frames 314 are forced to be supported and push the two groups of supporting rods 313 in opposite directions. The supporting rods 313 tilt and deflect and push the corresponding sliding frames 311 to move, and the damping spring shock absorber ring 312 is compressed. Since the concave and convex differences of the part surface contacted by the concave supporting frames 314 are too large, the angles of the two groups of supporting rods 313 pushed unidirectionally by some concave supporting frames 314 are inconsistent, which leads to inconsistent movement positions of the two groups of sliding frames 311. This adapts to the clamping limitations of irregular surfaces of irregular parts and reduces the possibility of irregular parts falling off.

[0038] It is worth noting that when clamping regular parts, the concave abutment frame 314 is abutted, and the abutment rods 313 at both ends are evenly stressed, which in turn pushes the corresponding sliding frame 311 to move at a uniform speed, and the damping spring shock-absorbing ring 312 is compressed, thereby facilitating the clamping of regular parts.

[0039] This structure is suitable for clamping irregular and regular parts, and can adaptively clamp irregular surfaces on multiple sides of irregular parts, reducing damage to irregular parts caused by hard clamping and improving part processing efficiency;

[0040] Example 2: After the irregular parts are processed by the clamping mechanism 3, there may be waste on the surface of the placement tray 35. The presence of waste can easily affect the flatness of the surface of the placement tray 35 and the stability of subsequent parts placement;

[0041] Please refer to Figure 1 and Figure 2 As shown, at one end of the front and rear inner walls of the cover frame 2, they are respectively rotatably connected to the front and rear inner walls of the operating table 1 through fixedly installed rotating rods. The two groups of rotating rods respectively extend to the outside of the cover frame 2 and are fixedly connected with limiting gears 201. An oval push frame 202 is commonly sleeved outside the two groups of limiting gears 201;

[0042] The oval push frame 202 is sleeved outside the operating table 1. A cylinder 203 is arranged on one side of the operating table 1 away from the cover frame 2, and the cylinder 203 is fixedly connected to the oval push frame 202 through a push rod. Rectangular slots are opened at the front and rear frames of the oval push frame 202 and at one end of the cover frame 2. Tooth groove groups are arranged on the top inner walls of the rectangular slots. The limiting gears 201 extend into the rectangular slots and mesh with the tooth groove groups;

[0043] Start the cylinder 203 to use the push rod to pull the oval push frame 202 to move, and the limiting gears 201 slide along the corresponding rectangular slots. The limiting gears 201 mesh with the tooth groove groups on the top inner walls of the rectangular slots to realize the clockwise rotation of the limiting gears 201 and the cover frame 2 by 90 degrees. Thus, the waste chips accumulated on the surface of the storage tray 35 will slide down accordingly, so as to realize automatic cleaning and reduce the clamping influence on subsequent irregular parts.

[0044] Embodiment 3: Please refer to Figure 3 and Figure 7 As shown, sleeve rings 38 are movably sleeved at the upper and lower ends of the sliding groove on the outside of the sliding rod 361. A spring coil group 39 is wound between the bottom sleeve ring 38 on the outside of the sliding rod 361 and the bottom inner wall of the clamping frame 36;

[0045] The adjusting assembly 4 includes a second motor 41. The second motor 41 is arranged near one side of the center of the top surface of the chassis 31. A driving gear 42 is fixedly installed at the top output end of the second motor 41. A rotating cylinder 43 is rotatably connected to the center of the top surface of the chassis 31. A driven toothed ring 44 is fixedly sleeved at the top opening of the rotating cylinder 43. The driving gear 42 meshes with the driven toothed ring 44. A round shaft 45 is fixedly installed at the center of the top inner wall of the rotating cylinder 43. A push cylinder 46 penetrates through the opening of the rotating cylinder 43, and the top end of the push cylinder 46 is fixedly connected to the bottom surface of the storage tray 35. A limiting inclined groove is arranged on the outside of the push cylinder 46, and the round shaft 45 is slidably connected to one end of the limiting inclined groove;

[0046] When adjusting the position of the parts, start the second motor 41 to drive the driving gear 42 to rotate. The driving gear 42 meshes with the driven gear ring 44 to realize the self-rotation of the rotating cylinder 43. The rotating cylinder 43 rotates relative to the pushing cylinder 46, and the round shaft 45 rotates along the inside of the limiting inclined groove, forcing the pushing cylinder 46 and the placing tray 35 to be pulled downward. The placing tray 35 sinks downward and moves relative to several groups of clamping frames 36. The sliding rod 361 penetrates up and down relative to the sliding groove, and the bottom of the placing tray 35 presses against several groups of collar rings 38 near the bottom respectively, and the spring coil 39 is compressed;

[0047] The parts on the surface of the placing tray 35 sink synchronously with the placing tray 35, forcing the distance between the elastic pressing components 310 at the top of the clamping frame 36 and the surface of the placing tray 35 to increase. Thus, the position height of the multiple groups of elastic pressing components 310 pressing against the outside of the parts changes accordingly;

[0048] This structure is used in cooperation with the material clamping mechanism 3, which is convenient for adaptively adjusting the clamping height according to the processing requirements of the parts, so as to improve the practicability of the device.

[0049] Working principle: When the present invention is in use, place the irregular parts to be processed at the center of the placing tray 35, start the first motor 32 to drive the turntable 33 to rotate, and several groups of hinge rods 34 rotate accordingly. Then use the vertical rod 37 to pull the corresponding clamping frame 36 to move, and multiple groups of clamping frames 36 move towards the center of the placing tray 35 at the same time;

[0050] When several groups of clamping frames 36 approach the parts, the concave pressing frame 314 first contacts the side wall of the parts. As the clamping frame 36 continues to press, the concave pressing frame 314 is forced and respectively pushes two groups of pressing rods 313 in the reverse direction. The pressing rods 313 deflect obliquely and respectively push the corresponding sliding frames 311 to move, and the damping spring shock-absorbing ring 312 is compressed. Due to the excessive difference in the convexity and concavity of the part surface contacted by the concave pressing frame 314, the angles of the two groups of pressing rods 313 unidirectionally pushed by some concave pressing frames 314 are inconsistent, resulting in inconsistent moving positions of the two groups of sliding frames 311, so as to adapt to the clamping limitation of the irregular surface of the irregular parts;

[0051] Meanwhile, when adjusting the position of the parts, the second motor 41 is started to drive the driving gear 42 to rotate. The driving gear 42 meshes with the driven gear ring 44 to realize the self-rotation of the rotating cylinder 43. The rotating cylinder 43 rotates relative to the pushing cylinder 46, and the round shaft 45 rotates along the inner part of the limiting inclined groove, forcing the pushing cylinder 46 and the placing tray 35 to be pulled downward. The placing tray 35 sinks downward and moves relative to several groups of clamping frames 36. The sliding rod 361 penetrates up and down relative to the sliding groove, and the bottom of the placing tray 35 respectively presses several groups of collar rings 38 near the bottom, and the spring coil 39 is compressed. The parts on the surface of the placing tray 35 sink synchronously with the placing tray 35, forcing the distance between the elastic pressing assembly 310 at the top of the clamping frame 36 and the surface of the placing tray 35 to increase. Thus, the position height of the multiple groups of elastic pressing assemblies 310 pressing on the outside of the parts changes accordingly to meet the requirements of various processing operations.

[0052] After the processing of the irregular parts is completed, the air cylinder 203 is started to drive the concave pushing frame 202 to move by means of the push rod. The limiting gear 201 slides along the corresponding rectangular groove. The limiting gear 201 meshes with the tooth groove group on the inner wall of the top of the rectangular groove to realize the clockwise rotation of the limiting gear 201 and the cover frame 2 by 90 degrees. Thus, the waste chips accumulated on the surface of the placing tray 35 will fall down along the trend, realizing automatic cleaning and reducing the clamping impact on the subsequent irregular parts.

Obviously, according to the content of this specification, many modifications and variations can be made.
