Description

Technical Field

[0001] This utility model belongs to the field of process equipment technology, specifically, it relates to a tooling fixture. Background Technology

[0002] Tooling fixtures, as devices for clamping workpieces, are used to fix the workpieces during machining. The stability and accuracy of their clamping of the workpieces are related to the dimensional accuracy and surface quality of the workpieces.

[0003] When machining workpieces with holes, related technologies typically use magnetic disks or vacuum chucks to clamp the workpieces. However, the magnetic force of the magnetic disks or the suction force of the chucks are easily affected by external factors, leading to instability in the magnetic force or suction force. This affects the reliability of clamping and the stability of the workpiece during machining, which in turn affects the machining accuracy and quality of the workpiece. Summary of the Invention

[0004] The purpose of this utility model is to provide a tooling fixture that, by setting a supporting mechanism in the fixture, internally supports and clamps the workpiece, thereby improving clamping stability and ease of operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A tooling fixture, comprising:

[0007] Base;

[0008] A sliding seat is disposed on the base, and a plurality of sliding grooves are formed on the sliding seat, each sliding groove extending from the center of the sliding seat to the outer edge;

[0009] The slider is a plurality of sliders, each slider being formed in a groove and sliding within the groove, and the inner side of the slider having a slider inclined surface;

[0010] A cover plate, the cover plate being configured to be close to or away from the slide seat, the cover plate having a plurality of cover plate inclined surfaces, each of the cover plate inclined surfaces abutting and slidingly engaging with the slider inclined surface of one of the sliders;

[0011] An adjustment mechanism is used to adjust the distance between the cover plate and the slide seat, so that the cover plate moves closer to or further away from the slide seat;

[0012] When the cover plate is close to the slide seat, the inclined surface of the cover plate slides relative to the inclined surface of the slider, and the slider slides outward in the slide groove in a direction away from the center of the slide seat; when the cover plate is away from the slide seat, the inclined surface of the cover plate slides relative to the inclined surface of the slider, and the slider slides inward in the slide groove in a direction close to the center of the slide seat.

[0013] In some embodiments of this application, the adjusting mechanism includes:

[0014] A sleeve that penetrates the slide seat in the thickness direction, and the bottom of the sleeve is fixed to the base; the sleeve has a hollow structure and threads are formed on the inner wall of the sleeve.

[0015] A first spring, the first end of which is placed inside the sleeve;

[0016] A first spring seat is located between the cover plate and the sleeve, and the second end of the first spring, which is opposite to the first end, abuts against the first spring seat.

[0017] A screw, which passes sequentially through the cover plate, the first spring seat and the first spring, and the end of the screw extends into the sleeve and is screwed into the thread on the inner wall of the sleeve;

[0018] When the screw rotates in a first direction, causing the end of the screw to move toward the bottom of the sleeve, it causes the cover plate and the first spring seat to move closer to the slide seat, and the first spring is compressed. When the screw rotates in a second direction, causing the end of the screw to move away from the bottom of the sleeve, the first spring releases its elastic force, pushing the first spring seat and the cover plate away from the slide seat.

[0019] In some embodiments of this application, the tooling fixture further includes:

[0020] A second spring is disposed within the slide groove and located between the bottom of the slide groove near the center of the slide groove seat and the slider located within the slide groove;

[0021] When the cover plate moves away from the slide seat, the inclined surface of the cover plate slides relative to the inclined surface of the slider, and the slider slides inward in the slide groove in a direction close to the center of the slide seat under the elastic force of the second spring.

[0022] In some embodiments of this application, the tooling fixture further includes:

[0023] A pressure plate, located above the cover plate and detachably connected to the cover plate and the slide seat, is used to limit the position of the workpiece held by the tooling fixture.

[0024] In some embodiments of this application, the pressure plate includes a clearance hole formed in the middle of the pressure plate and three pressure plate wings dispersed around the clearance hole. Each pressure plate wing has a pressure plate mounting hole. The clearance hole is used to avoid the adjustment mechanism on the cover plate. The pressure plate is detachably connected to the cover plate and the slide seat through the pressure plate mounting hole.

[0025] In some embodiments of this application, the slide groove extends from the center of the slide groove seat to the outer edge of the slide groove seat, and a slide groove notch communicating with the slide groove is formed on the outer edge of the slide groove seat; a slide groove guide rail or slide groove extending along the sliding direction of the slider is formed on the inner sidewall of the slide groove.

[0026] In some embodiments of this application, the slider includes:

[0027] A slider base portion, wherein the slider base portion is placed in the slide groove, and a slider guide groove or a slider guide rail that mates with the slide groove guide rail is formed on the slider base portion;

[0028] The slider body extends upward from the slider base, and the slider inclined surface is formed on the inner side of the slider body.

[0029] In some embodiments of this application, a protrusion is formed on the outer surface of the slider body for engaging with the inner surface of the workpiece to be clamped.

[0030] In some embodiments of this application, three slide grooves are formed on the slide seat, and there are three sliders.

[0031] In some embodiments of this application, the base includes:

[0032] Workpiece placement base;

[0033] A raised seat is located between the workpiece placement seat and the slide seat. The outer edge of the raised seat is located inside the outer edge of the workpiece placement seat, forming a workpiece operating space between the outer edge of the raised seat and the outer edge of the workpiece placement seat.

[0034] Compared with the prior art, the advantages and positive effects of this utility model are:

[0035] The tooling fixture provided by this utility model utilizes a sliding groove seat, a slider, a cover plate, and an adjusting mechanism to form a clamping mechanism. When the adjusting mechanism adjusts the cover plate closer to the sliding groove seat, the inclined surface of the cover plate slides relative to the inclined surface of the slider. The slider slides outward in the groove in a direction away from the center of the sliding groove seat, thus internally clamping the workpiece mounted on the outer ring of the fixture, achieving internal clamping of the workpiece. When the adjusting mechanism adjusts the cover plate away from the sliding groove seat, the inclined surface of the cover plate slides relative to the inclined surface of the slider. The slider slides inward in the groove in a direction closer to the center of the sliding groove seat, achieving separation from the workpiece. The sliding groove seat, slider, cover plate, and adjusting mechanism are used to achieve this clamping mechanism. The clamping mechanism provides stable and precise clamping force for the workpiece, ensuring accurate and stable positioning during machining. This effectively reduces vibration and displacement, while preventing workpiece deformation due to clamping force, thus meeting machining accuracy and quality requirements. The clamping and unclamping of the workpiece can be achieved simply by operating the adjustment mechanism, making operation convenient and allowing for fast workpiece clamping and changing, thereby improving machining efficiency. Furthermore, the clamping mechanism can accommodate workpieces of various shapes and sizes, enhancing the versatility and compatibility of the fixture.

[0059] To address the issues of low reliability and stability in workpiece clamping of existing tooling fixtures, this invention proposes a novel tooling fixture. This fixture utilizes a sliding groove seat, a slider, a cover plate, and an adjustment mechanism to form a support mechanism, which internally clamps the workpiece, improving clamping stability and ease of operation.

[0060] Figures 1 to 4 Some embodiments of the tooling fixture provided by this utility model are shown, wherein, Figure 1 , Figure 2 and Figure 3 These are, respectively, a perspective view, a sectional view, and an exploded view of this embodiment. Figure 4 This is a partial structural diagram of this embodiment.

[0061] See Figures 1 to 4 In some embodiments, the tooling fixture 100 includes a base 11, a slide seat 12, a slider 13, a cover plate 14, and an adjustment mechanism 15.

[0062] The base 11 serves as the overall base of the tooling fixture 100, supporting other components of the tooling fixture 100, placing the tooling fixture on the worktable for processing workpieces, and supporting the clamped workpieces.

[0063] In some embodiments, the base 11 includes a workpiece placement seat 111 and a raised seat 112 connected to each other. The raised seat 112 is located above the workpiece placement seat 111, and the outer edge of the raised seat 112 is located inside the outer edge of the workpiece placement seat 111. Thus, a workpiece operating space 113 is formed between the outer edge of the raised seat 112 and the outer edge of the workpiece placement seat 111, facilitating the processing of the workpiece using the workpiece operating space 113. In some embodiments, if the workpiece placement seat 111 is a cylinder and the raised seat 112 is also a cylinder, then the raised seat 112 is coaxially arranged with the workpiece placement seat 111, and the diameter of the raised seat 112 is smaller than the diameter of the workpiece placement seat 111.

[0064] The slide seat 12 is disposed on the base 11. When the base 11 includes a workpiece placement seat 111 and a raised seat 112, the slide seat 12 is disposed on the raised seat 112. A plurality of slide grooves 121 are formed on the slide seat 12, each slide groove extending from the center 122 of the slide seat to the outer edge 123 of the slide seat.

[0065] There are multiple sliders 13, and each slider 13 has a slider inclined surface 1321 formed on its inner side. The specific number of sliders 13 matches the number of grooves 121 on the slide seat 12. Each slider 13 is formed in a groove 121, and the slider 13 slides in the groove 121 along the extension direction of the groove 121.

[0066] In some embodiments, three grooves 121 are formed on the slide seat 12, and correspondingly, the number of sliders 13 is also three. The three grooves 121 are evenly distributed in the circumferential direction, so that the three sliders 13 provided in the three grooves 121 apply clamping force to the workpiece at three positions in the circumferential direction. The clamping force is evenly distributed, which improves the stability of clamping the workpiece and the accuracy of workpiece positioning.

[0067] The cover plate 14 is located above the slide seat 12 and is configured to move closer to or further away from the slide seat 12. In the illustrated embodiment, the cover plate 14 moves downward toward the slide seat 12; the cover plate 14 moves upward away from the slide seat 12. A plurality of cover plate inclined surfaces 141 are formed on the cover plate 14, the specific number of which matches the number of sliders 13. Each cover plate inclined surface 141 abuts against and slides with the slider inclined surface 1321 of one slider 13.

[0068] The adjustment mechanism 15 is used to adjust the distance between the cover plate 14 and the slide seat 12 so that the cover plate 14 is closer to or further away from the slide seat 12.

[0069] Furthermore, when the adjusting mechanism 15 adjusts the cover plate 14, causing it to move downwards and closer to the slide seat 12, the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider. The slider 13 will slide outwards within the slide groove 121 in a direction away from the center 122 of the slide seat. This outward sliding of the slider 13 can tighten the workpiece surrounding it, thus achieving internal tightening of the workpiece. Conversely, when the adjusting mechanism 15 adjusts the cover plate 14, causing it to move upwards and away from the slide seat 12, the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider. The slider 13 will slide inwards within the slide groove 121 in a direction close to the center 122 of the slide seat, achieving separation of the slider from the workpiece and facilitating workpiece disassembly.

[0070] In some embodiments, the slide groove 121 on the slide base 12 extends from the center 122 of the slide base to the outer edge 123 of the slide base. A slide groove notch 1212 communicating with the slide groove 121 is formed on the outer edge 123 of the slide base. A slide groove guide rail 1213 extending along the sliding direction of the slider 13, that is, the direction between the center 122 of the slide base and the outer edge 123 of the slide base, is formed on the inner sidewall of the slide groove 121. Correspondingly, a slider guide groove 1311 that slides and engages with the slide groove guide rail 1213 is formed on the slider 13. By providing the slide groove notch 1212, on the one hand, it is convenient to assemble and disassemble the slider 13 and replace the slider 13; on the other hand, when clamping the workpiece, the slider 13 can partially slide through the slide groove notch 1212 and be exposed outside the slide groove 121, so that the sliding stroke of the slider 13 is greater than the length of the slide groove 121, thereby increasing the sliding stroke of the slider 13, increasing the types of workpieces that can be clamped, and improving the application range of the tooling fixture. In other embodiments, a guide groove can be formed on the inner wall of the groove 121, and a slider rail can be formed on the slider 13 to slide smoothly and stably within the groove 121.

[0071] In some embodiments, the slider 13 includes a slider base portion 131 and a slider body portion 132. The slider base portion 131 is placed within a slide groove 121, and a slider guide groove 1311 or a slider rail is formed on the slider base portion 131. The slider body portion 132 extends upward from the slider base portion 131, and a slider inclined surface 1321 is formed on the inner side of the slider body portion 132. In other embodiments, a protrusion 1322 is formed on the outer side of the slider body portion 132 to match the inner side of the workpiece to be clamped, increasing the contact area between the slider 13 and the workpiece and increasing the clamping force on the workpiece. By configuring the slider 13 into two parts, a slider base portion 131 and a slider body portion 132, when adapting to the workpiece to be clamped, only the structure, shape, and size of the slider body portion 132 need to be adjusted, while the slider base portion 131 can remain unchanged. When the slider 13 needs to be modified, the number of parts of the slider 13 that need adjustment is reduced, lowering the cost and complexity of fixture manufacturing.

[0072] In some embodiments, the adjusting mechanism 15 includes a sleeve 151, a first spring 152, a first spring seat 153, and a screw 154.

[0073] The sleeve 151 penetrates the slide seat 12 in the thickness direction, i.e., the vertical direction, and the bottom of the sleeve 151 is fixed to the base 11. When the base 11 includes a workpiece placement seat 111 and a raised seat 112 arranged vertically, the bottom of the sleeve 151 is fixed to the raised seat 112. The sleeve 151 has a hollow structure and threads (not marked in the figure) are formed on its inner wall.

[0074] The first spring seat 153 is located between the cover plate 14 and the sleeve 151. The first end (lower end in the figure) of the first spring 152 is placed inside the sleeve 151, while the second end (upper end in the figure) of the first spring 152 abuts against the first spring seat 153. In some embodiments, the first spring seat 153 is formed with a guide post, and the second end of the first spring 152 is sleeved on the guide post to achieve the abutment between the first spring 152 and the first spring seat 153.

[0075] The screw 154 passes through the cover plate 14, the first spring seat 153 and the first spring 152 from top to bottom. The end of the screw 154 (the lower end in the figure) extends into the sleeve 151 and is screwed into the thread on the inner wall of the sleeve 151.

[0076] A nut is provided at the top of the screw 154 above the cover plate 14 (the upper end of the screw 154 in the figure). When the screw 154 is rotated in the first direction, the end of the screw 154 moves towards the bottom of the sleeve 151, and the nut moves downward, which will drive the cover plate 14 and the first spring seat 153 to move downward, close to the slide groove seat 12, and the first spring 152 is compressed. The cover plate 14 moves downward, and the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider. The slider 13 will slide outward in the slide groove 121 in a direction away from the center 122 of the slide groove seat. The slider 13 slides outward, supporting the workpiece surrounding the outside of the slider 13, thereby achieving the internal support of the workpiece. When workpiece separation is required, the screw 154 is rotated in a second direction opposite to the first direction. The end of the screw 154 moves upward away from the bottom of the sleeve 151, the nut moves upward, and the first spring 152 releases its elastic force. Under the action of the elastic force, the first spring seat 153 and the cover plate 14 are pushed upward away from the slide seat 12. When the cover plate 14 moves upward away from the slide seat 12, the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider. The slider 13 slides inward in the slide groove 121 in a direction close to the center 122 of the slide seat, thereby realizing the separation of the slider from the workpiece.

[0077] In some embodiments, the tooling fixture further includes a second spring 16 disposed within each slide groove 121. The portion of the slide groove 121 near the center 122 of the slide groove seat is the bottom 1211 of the slide groove. The second spring 16 is located between the bottom 1211 of the slide groove and the slider 13 disposed within the slide groove 121. When the cover plate 14 moves downward toward the slide groove seat 12, the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider, and the slider 13 slides outward within the slide groove 121 in a direction away from the center 122 of the slide groove seat, stretching the second spring 16. When the cover plate 14 moves upward away from the slide groove seat 12, the inclined surface 141 of the cover plate slides relative to the inclined surface 1321 of the slider, and the second spring 16 releases its elastic force. Under the action of the elastic force, the slider 13 slides inward within the slide groove 121 in a direction close to the center 122 of the slide groove seat. By providing the second spring 16, the sliding of the slider 13 in the slide groove 121 is achieved with a simple structure.

[0078] To increase the stability of the tooling fixture in clamping the workpiece, in some embodiments, the tooling fixture further includes a pressure plate 17. The pressure plate 17 is located above the cover plate 14 and is detachably connected to the cover plate 14 and the slide seat 12. (Refer to...) Figures 1 to 4 The tooling fixture shown, combined with Figure 5 The schematic diagram of the tooling fixture for clamping the workpiece shows that after the slider 13 clamps the workpiece 200 in place, the pressure plate 17 presses the workpiece down from the top surface. The pressure plate 17 is connected to the cover plate 14 and the slide seat 12. The pressure plate 17 applies a force to the workpiece 200 in the vertical Z direction, limiting the upward movement of the workpiece 200. Combined with the force applied to the workpiece 200 by the slider 13 in the X and Y directions, a multi-directional force can be applied to the workpiece 200, improving the stability of the workpiece 200 clamping, further preventing the workpiece from moving or loosening, and thus improving machining accuracy and machining safety.

[0079] In some embodiments, the pressure plate 17 includes a clearance hole 171 formed in the middle of the pressure plate and three pressure plate wings 172 dispersed around the clearance hole 171, with a pressure plate mounting hole 173 formed on each pressure plate wing 172. Furthermore, three slide seat mounting holes 124 are formed on the slide seat 12, and three cover plate mounting holes 142 are formed at corresponding positions on the cover plate 14. When assembling the pressure plate 17, the clearance hole 171 corresponds to the adjustment mechanism located on the cover plate 14, thus avoiding interference with the operation of the adjustment mechanism; screws 18 are passed through the pressure plate mounting holes 173 and the cover plate mounting holes 142 into the slide seat mounting holes 124, thereby achieving the assembly connection between the pressure plate 17 and the cover plate 14 and the slide seat 12. By setting the pressure plate 17 to a structure with a clearance hole 171 and three pressure plate wings 172, the up and down movement of the adjustment cover plate 14 of the operation adjustment mechanism is not affected. The three-point positioning structure of the three pressure plate wings 172 is used to limit the workpiece 200, which can avoid interference with the slider 13, achieve precise limiting and positioning of the workpiece, reduce the use of materials, and lower the cost.

[0080] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
