Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a screw processing fixture. Background Technology
[0002] A screw is a threaded fastener consisting of a head and a shank. It is mainly used to connect or fix two parts with through holes, and usually does not require a nut to achieve the fastening function.
[0003] When machining screws, a fixture is needed to hold them in place. However, existing fixtures cannot accurately hold screws in place and cannot collect the debris generated during machining. To solve these problems, a new type of fixture for screw machining is needed. Utility Model Content
[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing a screw processing fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A screw processing fixture includes a base, a support platform fixedly connected to the upper surface of the base, a fixing plate fixedly connected to the upper surface of the base, a rotating shaft rotatably connected to the surface of the fixing plate, an L-shaped clamping plate fixedly connected to the surface of the rotating shaft, a screw body placed on one side of the support platform, and a clamping and positioning mechanism provided on the inner wall of the base.
[0007] Preferably, the clamping and positioning mechanism includes an internally threaded sleeve fixedly connected to the inner wall of the support platform, a threaded rod threadedly connected to the inner wall of the internally threaded sleeve, a handwheel fixedly connected to the top end of the threaded rod, and the bottom end of the threaded rod contacting the surface of the L-shaped clamping plate.
[0008] Furthermore, a rounded head is fixedly connected to the bottom end of the threaded rod, and the surface of the rounded head contacts the surface of the L-shaped clamp.
[0009] Preferably, a plurality of return springs are fixedly connected to the inner wall of the support platform, and one end of the return spring is fixedly connected to the surface of the L-shaped clamp.
[0010] Furthermore, the surface of the support platform is provided with multiple slots that are adapted to the surface of the screw body, and the surface of the L-shaped clamp is provided with multiple extrusion grooves that correspond to the positions of the slots.
[0011] Preferably, a pair of load-bearing plates are fixedly connected to the surface of the support platform, and magnets are fixedly connected to the inner walls of the load-bearing plates. A garbage box is fitted onto the surface of the support platform, and the magnets are magnetically attracted to the garbage box.
[0012] The beneficial effects of this utility model are as follows:
[0013] When fixing multiple screw bodies, the operator turns the handwheel to press the rounded head against the surface of the L-shaped clamp. At this time, the L-shaped clamp rotates and adjusts around the rotating shaft to bring the pressing groove close to the surface of the screw body for pressing. The processing debris falls into the waste box for collection. The advantage of doing this is that it can accurately clamp and fix multiple screw bodies simultaneously and facilitates the collection of debris. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-5 A screw processing fixture includes a base 1, a support platform 2 fixedly connected to the upper surface of the base 1, a fixing plate 9 fixedly connected to the upper surface of the base 1, a rotating shaft 5 rotatably connected to the surface of the fixing plate 9, an L-shaped clamping plate 3 fixedly connected to the surface of the rotating shaft 5, a screw body 4 placed on one side of the support platform 2, and a clamping and positioning mechanism provided on the inner wall of the base 1.
[0022] By setting up a support platform 2, installing a fixing plate 9 and an internal threaded sleeve 8, multiple screw bodies 4 are placed and supported at the same time. By setting up a rotating shaft 5, the rotation of the L-shaped clamp 3 is kept stable. By setting up the L-shaped clamp 3, multiple screw bodies 4 are squeezed and clamped. By setting up a clamping and positioning mechanism, multiple screw bodies 4 are synchronously positioned and clamped, while facilitating the collection of debris generated during processing.
[0023] In this utility model, reference Figure 2 The clamping and positioning mechanism includes an internally threaded sleeve 8 fixedly connected to the inner wall of the support platform 2. The inner wall of the internally threaded sleeve 8 is threadedly connected to a threaded rod 6. A handwheel 15 is fixedly connected to the top of the threaded rod 6, and the bottom of the threaded rod 6 is in contact with the surface of the L-shaped clamping plate 3.
[0024] By setting the internal threaded sleeve 8, the rotation of the threaded rod 6 is kept stable, and by setting the handwheel 15, the height position of the threaded rod 6 is adjusted.
[0025] In this utility model, reference Figure 2 The bottom end of the threaded rod 6 is fixedly connected to a rounded head 16, and the surface of the rounded head 16 is in contact with the surface of the L-shaped clamp 3.
[0026] By setting the rounded corner head 16, the surface of the L-shaped clamp 3 is pressed, causing the L-shaped clamp 3 to rotate under force.
[0027] In this utility model, reference Figure 2 Multiple return springs 7 are fixedly connected to the inner wall of the support platform 2, and one end of the return spring 7 is fixedly connected to the surface of the L-shaped clamp 3.
[0028] By setting a reset spring 7, the L-shaped clamp 3 is rotated to reset.
[0029] In this utility model, reference Figure 3 and Figure 4 The surface of the support platform 2 is provided with multiple slots 13, which are adapted to the surface of the screw body 4. The surface of the L-shaped clamp 3 is provided with multiple extrusion grooves 14, which are corresponding to the positions of the slots 13.
[0030] By setting the slot 13, space is provided for placing the screw body 4, and by setting the pressing groove 14, the surface of the screw body 4 is pressed and positioned.
[0031] In this utility model, reference Figure 3 and Figure 5 A pair of load-bearing plates 11 are fixedly connected to the surface of the support platform 2. Magnets 12 are fixedly connected to the inner wall of the load-bearing plates 11. A garbage box 10 is fitted onto the surface of the support platform 2. The magnets 12 and the garbage box 10 are magnetically attracted to each other.
[0032] By setting up a load-bearing plate 11, the garbage box 10 is supported and placed. By setting up the garbage box 10, processing debris is collected. By setting up a magnet 12, the garbage box 10 is kept stable on the load-bearing plate 11.
[0033] Working principle: During use, multiple screw bodies 4 are placed in the slots 13 on the support platform 2. The operator turns the handwheel 15, which drives the threaded rod 6 to rotate, causing the rounded head 16 to press against the surface of the L-shaped clamp 3. The compression return spring 7 shortens, and the L-shaped clamp 3 rotates around the rotating shaft 5 to adjust the compression groove 14 to approach the surface of the screw body 4 for compression and clamping. When reset is required, the operator reverses the handwheel 15, and the L-shaped clamp 3 is reset under the action of multiple return springs 7, thereby removing the screw body 4 placed in the slot 13. During processing, debris falls into the waste box 10 for collection, which can be cleaned by removing the waste box 10 installed on the support platform 2.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
