Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figure 1 As shown, a workpiece processing fixture according to one embodiment of the present invention includes a support component 1, a power component 2 installed on the inner wall of the support component 1, a pair of clamping components 3 matched with the support component 1 installed on the power component 2, and a control component 4 rotatably connected to one side wall of each pair of clamping components 3. An anti-slip component 5 matched with the clamping components 3 is threadedly connected to the inner wall of the control component 4. In use, the power component 2 is first controlled to move the pair of clamping components 3 on the support component 1 to clamp the workpiece. After clamping is completed, the control component 4 is operated to drive the anti-slip component 5 to perform a secondary clamping of the workpiece, which increases the friction coefficient between the workpiece and the clamping components 3, thereby increasing the stability of the workpiece during processing.

[0030] like Figure 2 As shown, the support assembly 1 includes a support base 101, and a collection bin 102 is provided on one side wall of the support base 101. When processing workpieces, debris is often generated. The accumulation of these debris on the workbench can easily affect the processing of workpieces and requires frequent cleaning. Therefore, the debris generated during workpiece processing can fall into the collection bin 102, keeping the workbench clean and tidy, and increasing work efficiency and quality.

[0031] like Figures 1-2 and Figure 5As shown, the first through hole 1011 is arranged on one end side wall of the support base 101, and a first bearing is mounted on the inner wall of the first through hole 1011. The power assembly 2 comprises a bidirectional screw 201 and a fixed column 202. One end of the bidirectional screw 201 is rotatably connected to the inner wall of the support base 101, and the other end of the bidirectional screw 201 penetrates and is fixedly connected to the inner ring of the first bearing. The end of the bidirectional screw 201 close to the first through hole 1011 is fixedly connected with a rotating knob 203, and the two ends of the fixed column 202 are fixedly connected to the inner wall of the support base 101. The rotating knob 203 is located on one side of the outer wall of the support base 101. The clamping assembly 3 comprises a clamping shell 301, and the bottom end face of the clamping shell 301 is fixedly connected with a first mounting block 302. A first threaded hole 3021 matched with the bidirectional screw 201 is arranged on the outer wall of the first mounting block 302. The bottom end face of the clamping shell 301 is fixedly connected with a second mounting block 303 matched with the fixed column 202 at a position opposite to the first mounting block 302, and a second through hole 3031 is arranged on the outer wall of the second mounting block 303. A pair of first sliding grooves 1012 matched with the clamping assembly 3 are arranged on the top end face of the support base 101, and the top end side walls of the first mounting block 302 and the second mounting block 303 are slidably connected to the inner walls of the first sliding grooves 1012. By manually rotating the rotating knob 203 to drive the bidirectional screw 201 to rotate, the bidirectional screw 201 drives the pair of clamping assemblies 3 to move in opposite directions at the same time, the first mounting block 302 is screwed to the bidirectional screw 201 through the first threaded hole 3021, and the second mounting block 303 is slid on the outer side wall of the fixed column 202 through the second through hole 3031, so as to clamp and loosen the workpiece by the clamping assembly 3.

[0032] Further, anti-skid lines are integrally formed on the clamping end faces of the pair of clamping shells 301, further enhancing the stability of the workpiece during clamping.

[0033] As Figure 3 and Figures 5-7As shown, a pair of second sliding grooves 3011 matched with the anti-skid assembly 5 are arranged on the inner wall of the clamping shell 301, the anti-skid assembly 5 comprises a fixed plate 501, and a clamping block 5011 matched with the second sliding groove 3011 is integrally formed on the outer wall of each end of the fixed plate 501, the outer wall of the clamping block 5011 slides on the inner wall of the second sliding groove 3011, a circular hole is arranged on the side wall of the fixed plate 501 away from the anti-skid column 502, a second bearing is installed in the circular hole, and a threaded rod 503 is installed on the inner ring of the bearing. An installation hole 304 is arranged on the side wall of the clamping shell 301, a limiting ring 305 is welded on the side of the clamping shell 301 and located on one side of the installation hole 304, a T-shaped limiting groove 3051 matched with the control assembly 4 is arranged on the side wall of the limiting ring 305, the control assembly 4 comprises a rotating column 401, a clamping ring 402 matched with the T-shaped limiting groove 3051 is integrally formed on the side wall of the rotating column 401, the outer wall of the clamping ring 402 is rotationally connected to the inner wall of the T-shaped limiting groove 3051, and a second threaded hole 4011 matched with the threaded rod 503 is arranged on the side wall of the rotating column 401. A plurality of groups of avoiding grooves 306 matched with the anti-skid assembly 5 are arranged on the end side wall of the clamping shell 301 away from the limiting ring 305, and a plurality of groups of anti-skid columns 502 matched with the avoiding grooves 306 are fixedly connected to the side wall of the fixed plate 501. When the clamping assembly 3 clamps the workpiece, the rotating column 401 is manually rotated to drive the clamping ring 402 to rotate on the inner wall of the T-shaped limiting groove 3051 while being threadedly connected with the threaded rod 503, so that the threaded rod 503 moves forward and backward while rotating, and the threaded rod 503 rotates on the side of the fixed plate 501 under the action of the second bearing while rotating, and drives the fixed plate 501 and the anti-skid column 502 to move, so that the clamping block 5011 slides on the inner wall of the second sliding groove 3011, and the side wall of the plurality of groups of anti-skid columns 502 is attached to the side wall of the workpiece. At this time, the anti-skid column 502 is slightly deformed under extrusion, thereby realizing secondary fixation of the workpiece, increasing the friction between the workpiece and the two side fixing members, and avoiding slipping or displacement of the workpiece during machining.

[0034] Preferably, the material of the anti-skid column 502 is high-strength silicone rubber, which has the characteristics of wear resistance, not easy to wear, and anti-skid. A plurality of groups of anti-skid columns 502 are extruded and clamped on both sides of the workpiece at the same time, thereby increasing the stability of the workpiece.

[0035] Further, when the workpiece is not clamped, the rotating column 401 is reversely rotated to drive the anti-skid column 502 to move into the clamping shell 301, thereby avoiding the anti-skid column 502 from being exposed to the outside to cause bumping, and avoiding dust adsorption to affect the machining quality of the workpiece.

[0036] As shown in the figure, Figure 4As shown, the length of the anti-skid column 502 is the maximum length of the protruding side of the clamping shell 301 after penetrating the avoiding groove 306, and in the normal use state, the anti-skid column 502 slightly protrudes or does not protrude from the side of the clamping shell 301, and is slightly compressed and deformed in the avoiding groove 306 on both sides of the workpiece; when encountering slightly uneven workpieces, the anti-skid column 502 at the corresponding position of the workpiece recess protrudes from the side of the clamping shell 301 through the avoiding groove 306 and is attached to the recess, thereby fixing the uneven workpiece.

[0037] In use, the workpiece is clamped and fixed by operating the power assembly 2 to realize clamping and fixing of the workpiece by a pair of clamping assemblies 3, and the workpiece is fixed again by rotating the control assembly 4 to drive the anti-skid assembly 5, at this time the anti-skid column 502 penetrates the avoiding groove 306 and extrudes the side wall of the workpiece, avoiding the phenomenon of slipping of the workpiece during processing, increasing the stability of the workpiece during processing, and most of the debris generated during processing automatically falls into the collecting bin 102, and a small part of the debris falls onto the top end face of the supporting assembly 1, so that the worker only needs to occasionally use a brush to brush the debris into the supporting assembly 1, and after accumulating to a certain amount, it is concentrated and cleaned from the collecting bin 102, thereby reducing the number of times of cleaning the debris by the worker, and increasing the work efficiency.

[0038] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.

[0039] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
