Description

Technical Field

[0001] This utility model relates to the field of steel leaf spring processing technology, specifically to a steel leaf spring sawing positioning plate clamp. Background Technology

[0002] In practical applications, the rolled or wrapped lugs of leaf springs and guide arms often need to be processed into a half-section rolled or wrapped lug structure. The existing processing technology usually adopts the method of "combining parts for processing and then sawing": first, the two workpieces are combined and processed into a rolled or wrapped lug structure at both ends, and then sawn from the middle position of the two center holes to meet the product design requirements.

[0003] In existing sawing processes, due to workpiece machining errors, the actual distance between the two center holes may deviate from the theoretical value. The traditional sawing method is to first manually draw a center line between the two center holes, then place the workpiece on the sawing machine, fix it with the sawing machine clamping device, and then make the saw blade align with the center line for cutting. This eliminates the need for complex training for workers and improves convenience.

[0004] However, due to operational experience and visual errors, there is a certain deviation between the center line and the actual center position of the two holes (approximately 0.5-2mm). This can lead to inaccurate sawing benchmarks. Furthermore, when manually adjusting the overlap between the saw blade or saw arm and the marked line (i.e., adjusting the saw blade or saw arm to be directly above the marked line), operational deviations can easily amplify the positioning error. In severe cases, this can lead to a large dimensional deviation between the two sections of the workpiece after cutting, which will affect the consistency and pass rate of the workpiece dimensions, and consequently affect subsequent production and sales. Utility Model Content

[0005] In view of this, the present invention provides a steel plate spring sawing positioning plate clamp, which can flexibly adjust the relative position of the positioning pins according to the actual deviation of the distance between the center holes of the workpiece through the symmetrically arranged adjustment grooves and the slidably connected positioning pins on the base plate, so as to ensure that the positioning pins are accurately inserted into the center holes of workpieces of different specifications. This solves the problem of inaccurate sawing benchmark caused by visual errors in traditional manual line drawing positioning, and significantly improves the positioning accuracy and workpiece size consistency.

[0006] To solve the above-mentioned technical problems, this utility model provides a steel plate spring sawing positioning plate clamp, including a base plate, with symmetrical adjustment grooves on the upper part of the base plate. The adjustment grooves are set in a rectangular keyway structure, and a positioning post is slidably connected in each adjustment groove along the lateral direction.

[0007] The positioning pin is designed as a cylindrical structure to fit and be inserted into the center hole of the workpiece.

[0008] The bottom of the positioning post is designed with a tapered structure to accommodate positioning requirements of different center hole diameters on the workpiece.

[0009] A guide cylinder is fixedly connected to the outer wall of the positioning column. The guide cylinder is located in the adjustment groove and is used to guide the positioning column.

[0010] An adjusting rod is provided at the upper end of the positioning column along the lateral movement direction (i.e., an adjusting rod is provided on the side of the upper end of the positioning column facing the center of the base plate). An adjusting mechanism is provided on the side of the adjusting rod facing the center of the base plate to adjust the position of the adjusting rod, thereby adjusting the position of the positioning column.

[0011] The upper part of the base plate is symmetrically provided with brackets, which are connected to the upper part of the base plate by bolts, and the adjustment mechanism is set on the corresponding bracket.

[0012] The adjustment mechanism includes a sleeve mounted on a vertical surface on the side of the bracket facing the center of the base plate. The sleeve is rotatably connected to the bracket via a bearing. An adjustment screw is fixedly connected to the end of the adjustment rod facing the bracket. The adjustment screw is threadedly connected to the sleeve.

[0013] The adjusting rod is fixedly connected to a positioning screw at the end away from the bracket. The upper end of the positioning post is slidably connected to the outer wall of the positioning screw, that is, the upper end of the positioning post is set as a rectangular structure. The positioning post has a through hole corresponding to the position of the positioning screw. The positioning post is slidably connected to the outer wall of the positioning screw through the mounting hole. The positioning nut is threadedly connected to the side of the positioning post away from the bracket and to the positioning screw, which facilitates quick assembly and disassembly of the positioning post. The positioning nut is used to lock the positioning post to the positioning screw.

[0014] A support column is fixedly connected to the opposing surfaces of the two sleeves, allowing the two sleeves to rotate synchronously.

[0015] The diameter of the support column is smaller than the diameter of the sleeve, so that a positioning groove is formed between the support column and the two sleeves, which is used to position the saw blade or saw arm.

[0016] An anti-slip layer made of rubber is fixedly connected to the outer wall of the sleeve to prevent the operator's hands from slipping when adjusting the sleeve.

[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0018] 1. Precise positioning and adaptive adjustment: The positioning pins are symmetrically arranged on the base plate and slidably connected. The relative position of the positioning pins can be flexibly adjusted according to the actual deviation of the distance between the center holes of the workpiece. This ensures that the positioning pins are accurately inserted into the center holes of workpieces of different specifications. It solves the problem of inaccurate sawing benchmark caused by visual errors in traditional manual line drawing positioning, and significantly improves the positioning accuracy and workpiece size consistency.

[0019] 2. Universal compatibility and convenient efficiency: The positioning post adopts a cylindrical body with a tapered structure at the bottom, which can not only form a precise positioning with the circular center hole with full circumference, but also automatically center the workpiece hole with different diameter through the tapered surface. There is no need to frequently change the positioning post, reducing operation steps and improving processing efficiency. The guiding effect of the tapered end can also effectively avoid the interference of burrs at the hole opening and reduce the risk of hole damage.

[0020] 3. Stable guidance of the positioning column: The guide cylinder on the outside of the positioning column is adapted to the adjustment groove to limit the lateral offset or shaking of the positioning column, ensuring that it slides smoothly in the lateral direction, providing a stable positioning reference for the workpiece, and avoiding sawing accuracy deviation caused by the shaking of the positioning column.

[0021] 4. Easy maintenance and replacement of positioning pins: The design of the adjusting rod, positioning screw, and positioning nut enables quick disassembly and locking of the positioning pins, meeting the positioning requirements of workpieces of different thicknesses and enhancing the versatility of the fixture.

[0022] 5. Synchronous adjustment of positioning columns: The two side sleeves rotate in conjunction with the support columns, so that the positioning columns move symmetrically towards or away from each other, ensuring that the workpiece is centered on the base plate and eliminating unilateral adjustment errors.

[0023] 6. Sawing accuracy guaranteed: The positioning groove formed by the support column and the rotating sleeve provides a clear cutting path reference for the saw blade. The operator only needs to align the saw blade with the positioning groove to avoid visual deviations caused by manual tool setting, fundamentally ensuring the consistency between the sawing position and the theoretical center, and greatly reducing the workpiece size deviation and scrap rate.

[0024] 7. Improved ease of operation and installation reliability: The anti-slip layer design on the outside of the sleeve improves the stability of the operator's grip when manually adjusting, and avoids slippage that leads to loss of control during adjustment; the threaded drive adjustment mechanism can achieve minute and precise adjustment of the positioning column position, and with the locking function of the positioning nut, it effectively resists vibration interference during the sawing process, ensuring stable positioning throughout the entire processing process, combining ease of operation and structural reliability.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0037] A steel leaf spring sawing positioning plate clamp, such as Figure 1 , 3 As shown: It includes a base plate 101, and the upper part of the base plate 101 is symmetrically provided with adjustment grooves 102. Each adjustment groove 102 is slidably connected with a positioning post 103 in the transverse direction. The positioning post 103 slides in the adjustment groove 102, so as to adjust and position steel leaf spring workpieces with different center hole spacings.

[0038] When the distance between the center holes of the workpiece changes, the relative positions of the two positioning pins 103 can be adjusted to ensure that the positioning pins 103 are accurately inserted into the center holes of the workpiece, thus avoiding positioning failure caused by differences in workpiece specifications.

[0039] Furthermore, the positioning post 103 is set as a cylindrical structure to fit and insert into the center hole of the workpiece. The center hole of the steel leaf spring is usually designed as a circle. The circular positioning post 103 is perfectly matched with the workpiece hole. When the positioning post 103 is inserted into the center hole, the two form a surface contact (i.e., the two arc surfaces fit together), avoiding the local gap that may be generated by the square or polygonal structure, thereby ensuring positioning accuracy.

[0040] When the circular cross-section positioning post 103 is inserted into the workpiece hole, there is no need to align it with an angle. It can be inserted smoothly simply by axial alignment. Furthermore, the cylindrical shape avoids uneven force distribution during sliding. When the positioning post 103 slides in the adjustment groove 102, it extends the service life of the positioning post 103 and prevents damage to the workpiece hole.

[0041] Preferably, the bottom end of the positioning post 103 is set as a conical structure to meet the positioning requirements of different center hole diameters of the workpiece (generally, the center hole diameter of the steel leaf spring is φ10.5mm-φ16.5mm). When the positioning post 103 is inserted, the conical surface will automatically guide the positioning post 103 to align with the center of the workpiece hole, ensuring that the axis of the positioning post 103 coincides with the workpiece hole.

[0042] The same positioning post 103 can be adapted to workpiece holes of different diameters through its tapered end. When positioning workpiece holes of different diameters, it is not necessary to frequently replace the positioning post 103, which saves positioning efficiency and improves cutting speed.

[0043] The guiding effect of the tapered tip can also reduce the difficulty of inserting the positioning post 103 into the workpiece hole. The tapered end can also effectively avoid burrs at the hole opening from hindering positioning. Furthermore, the progressive contact method of the tapered structure reduces the impact force on the edge of the workpiece hole, reduces the risk of hole opening damage, and improves the workpiece yield.

[0044] like Figure 1 , 3 As shown: A guide cylinder 201 is fixedly connected to the outer wall of the positioning post 103. The guide cylinder 201 is located in the adjustment groove 102 and is used to guide the positioning post 103. The structure of the guide cylinder 201 is adapted to the adjustment groove 102 so that the guide cylinder 201 can slide along the lateral direction of the adjustment groove 102 when the positioning post 103 moves, avoiding lateral offset or shaking, thereby ensuring the accuracy of workpiece positioning and avoiding insufficient sawing accuracy due to position deviation.

[0045] like Figure 1 , 2 As shown: An adjusting rod 104 is provided on the upper end of the positioning column 103 along the lateral movement direction (that is: an adjusting rod 104 is provided on the side of the upper end of the positioning column 103 facing the center of the base plate 101). An adjusting mechanism is provided on the side of the adjusting rod 104 facing the center of the base plate 101 to adjust the position of the adjusting rod 104, thereby adjusting the position of the positioning column 103. A bracket 105 is symmetrically provided on the upper part of the base plate 101. The bracket 105 is connected to the upper part of the base plate 101 by bolts. The adjusting mechanism is provided on the corresponding bracket 105.

[0046] The bracket 105 is provided so that the adjustment mechanism can be supported thereon, and the adjustment rod 104 and the positioning column 103 connected to the end of the adjustment rod 104 can be supported. Then, the position of the positioning column 103 can be adjusted by the adjustment mechanism.

[0047] like Figure 2 , 3 As shown: The adjustment mechanism includes a sleeve 301 disposed on the vertical surface of the bracket 105 facing the center of the base plate 101. The sleeve 301 is rotatably connected to the bracket 105 via a bearing. An adjustment screw 302 is fixedly connected to one end of the adjustment rod 104 facing the bracket 105. The adjustment screw 302 is threadedly connected to the sleeve 301.

[0048] When the rotating sleeve 301 is rotated, the adjusting screw 302 will drive the positioning pin 103 to move laterally in the adjusting groove 102, thereby accurately adjusting the horizontal position of the positioning pin 103. This can adapt to the center hole requirements of workpieces of different specifications, and adjust the positioning point according to the sawing process requirements to ensure the accurate position of the workpiece installation.

[0049] like Figure 3 As shown: The adjusting rod 104 is fixedly connected to a positioning screw 401 at the end away from the bracket 105. The upper end of the positioning post 103 is slidably connected to the outer wall of the positioning screw 401. That is, the upper end of the positioning post 103 is set as a rectangular structure. A mounting hole (set to fit the shape of the positioning screw 401) is opened through one vertical face of the positioning post 103 at the position corresponding to the positioning screw 401. The positioning post 103 is slidably connected to the outer wall of the positioning screw 401 through the mounting hole. A positioning nut 402 is threadedly connected to the positioning post 103 on the side away from the bracket 105 and to the positioning screw 401, which facilitates quick installation and removal of the positioning post 103. The positioning nut 402 is used to lock the positioning post 103 to the positioning screw 401.

[0050] The positioning nut 402 works in conjunction with the positioning screw 401. After tightening the positioning nut 402, the positioning post 103 can be clamped and fixed. During the sawing process, the positioning nut 402 can resist vibration force and prevent the positioning post 103 from shifting laterally, ensuring the stability of the workpiece positioning, avoiding sawing deviation caused by delivery, and facilitating the replacement of the positioning post 103 according to the thickness of the workpiece. It also facilitates the maintenance of the positioning post 103 and improves the applicability of the overall structure.

[0051] like Figure 1 , 4As shown: A support column 501 is fixedly connected to the facing surfaces of the two rotating sleeves 301, so that the two rotating sleeves 301 can rotate synchronously and the positioning columns 103 on both sides can move symmetrically (that is, the positioning columns 103 on both sides can move towards each other or away from each other), ensuring that the workpiece remains centered in the base plate 101, avoiding the sawing position shift due to unilateral positioning deviation, thereby improving sawing accuracy and workpiece processing consistency.

[0052] Furthermore, the diameter of the support column 501 is smaller than the diameter of the sleeve 301, so that a positioning groove 601 is formed between the support column 501 and the two sleeves 301. This groove is used to position the saw blade or saw arm. After the workpiece is clamped by the sawing machine's fixture, the position of the saw blade is aligned with the position of the positioning groove 601. Then, the sawing positioning plate can be removed, and the sawing process of the workpiece can begin. This provides a basis for the cutting path of the saw blade, ensures the accuracy of the sawing position, and avoids the scrapping of the workpiece due to the positioning deviation of the saw blade.

[0053] like Figure 4 As shown: An anti-slip layer 701 is fixedly connected to the outer wall of the sleeve 301. The protective layer is made of rubber and is used to prevent the operator's hand from slipping when adjusting the sleeve 301. It allows the operator to quickly rotate the sleeve 301 to adjust the position of the positioning column 103.

[0054] When using:

[0055] Place the workpiece on the saw and rotate the forward or reverse rotating sleeve 301. The positioning pins 103 on both sides will move towards each other or away from each other until the distance between the positioning pins 103 on both sides is consistent with the distance between the center hole of the workpiece. The positioning pins 103 then enter the hole to complete the positioning.

[0056] Adjust the front and rear positions of the workpiece so that the positioning groove 601 in the middle of the saw positioning plate sleeve 301 (i.e., the positioning groove 601 formed between the support column 501 and the two sleeves 301) is aligned with the saw blade.

[0057] The workpiece is clamped by the fixture on the sawing machine, the saw blade is raised, and the sawing positioning plate is removed before the sawing process can begin.

[0058] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0059] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
