Because the box cover is the plate structure with small thickness size, the existing clamping tool can only clamp and fix the outer periphery of the box cover, therefore, when processing and producing the special-shaped box cover, the staff needs to clamp and fix the box cover at a specific angle first, after a part of the outer periphery of the box cover is turned and processed into shape, the angle of the box cover is adjusted to turn and process another part of the outer periphery of the box cover into shape, the operation is complicated, time-consuming and laborious, and the production efficiency is affected. SUMMARY

[0003] The utility model solves the technical problem that the prior art exists, provides a box cover turning and pressing tool that is simple and convenient to operate, good in fixing stability, can effectively improve production quality and production efficiency.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A box cover turning and pressing tool, including tool body, fastener and pressing piece, the middle part of tool body is equipped with connecting hole, the fastener passes through the pressing piece and is connected in the connecting hole, so that the workpiece is pressed between the pressing piece and the tool body.

[0006] As a further improvement of the above technical scheme:

[0007] The fastener is a screw, the connecting hole is an internal thread blind hole, and the fastener is screwed into the connecting hole.

[0008] The tool body is provided with a plurality of sets of positioning structures for positioning the workpiece.

[0009] The positioning structure includes a protrusion or a groove matched with the end face of the workpiece.

[0010] The bottom of the tool body is provided with a journal portion for clamping by a lathe chuck.

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] This utility model's box cover turning clamping fixture includes a fixture body, fasteners, and a clamping plate. When clamping the workpiece, the workpiece is first placed on the fixture body, the clamping plate is placed on the workpiece, and then the fastener passes through the clamping plate and the workpiece in sequence and connects with the connecting hole on the fixture body, thereby pressing the workpiece between the clamping plate and the fixture body. This replaces the existing working method of clamping and fixing the outer circumference of the box cover with a fixture, allowing the turning tool to perform full circumferential turning along the outer circumference of the box cover without repeatedly adjusting the workpiece angle. It has the advantages of simple and convenient operation and good fixing stability, and can effectively improve production quality and production efficiency. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figs. 1 to 3 As shown, the box cover turning clamping fixture of this embodiment includes a fixture body 1, a fastener 2, and a clamping plate 3. A connecting hole 101 is provided in the middle of the fixture body 1. The fastener 2 passes through the clamping plate 3 and is connected in the connecting hole 101, so that the workpiece 100 is clamped between the clamping plate 3 and the fixture body 1. When clamping the workpiece 100, the workpiece 100 is first placed on the fixture body 1, the clamping plate 3 is placed on the workpiece 100, and then the fastener 2 passes through the clamping plate 3 and the workpiece 100 in sequence and is connected to the connecting hole 101 on the fixture body 1, thereby clamping the workpiece 100 between the clamping plate 3 and the fixture body 1. This replaces the existing working method of clamping and fixing the outer circumference of the box cover with a fixture, so that the turning tool can perform full circumferential turning along the outer circumference of the box cover without repeatedly adjusting the angle of the workpiece 100. It has the advantages of simple and convenient operation and good fixing stability, and can effectively improve production quality and production efficiency.

[0020] Preferably, the fastener 2 is a screw, the connecting hole 101 is an internally threaded blind hole, and the fastener 2 is screwed into the connecting hole 101. In the embodiment, the fastener 2 and the connecting hole 101 are connected by screwing, which has the advantages of simple structure, high connection reliability, and convenient assembly and disassembly. Moreover, the spacing between the pressing sheet 3 and the tool body 1 can be freely adjusted by screwing the fastener 2 into or out of the connecting hole 101, thereby meeting the clamping requirements of workpieces 100 of different thicknesses, having high flexibility in use, and having a wide range of applications.

[0021] Preferably, the tool body 1 is provided with a plurality of sets of positioning structures 102 for positioning the workpiece 100, which can prevent the workpiece 100 from rotating relative to the tool body 1 during turning.

[0022] Preferably, the positioning structure 102 includes a protrusion or a groove matched with the end face of the workpiece 100. In the embodiment, since the workpiece 100 is provided with a recess, the positioning structure 102 on the tool body 1 is in the form of a protrusion, the number of the protrusions is four, and the shape of the protrusion is a circular arc, which can make the end face of the workpiece 100 closely match the top surface of the tool body 1, thereby improving the stability of the workpiece 100 on the tool body 1 and ensuring the machining accuracy. In other embodiments, the workpiece 100 is provided with a protrusion, and the positioning structure 102 on the tool body 1 is in the form of a groove, the number and shape of which can be adaptively adjusted according to actual production requirements, which is not limited to the embodiment and has the advantage of a wide range of applications.

[0023] Preferably, the bottom of the tool body 1 is provided with a journal portion 103 for clamping by a lathe chuck. In the embodiment, the bottom of the tool body 1 is provided with the journal portion 103. After the workpiece 100 is tightly fixed between the pressing sheet 3 and the tool body 1, the tool body 1 can be directly clamped and assembled on the lathe chuck, the workpiece 100 is driven to rotate by the lathe chuck, and the corresponding milling machining is completed in cooperation with the turning tool, thereby having high flexibility in use.

[0024] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-described embodiments. Improvements and changes made by those skilled in the art without departing from the technical concept of the present application should also be considered as falling within the protection scope of the present application.
