Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a special tooling for parts processing. Background Art

[0002] In mechanical processing, some special-shaped parts are often processed. These parts are difficult to clamp, resulting in low processing efficiency. Figure 4 As shown in the figure. The workpiece is tubular and has a groove on its outer wall along its axial direction. During processing, the tubular workpiece needs to be clamped first, and then the groove is opened on its surface. Since the workpiece is very small, clamping is difficult. At the same time, only one piece can be processed each time, and the grooving time after clamping is very short, making clamping the main action of the part processing, and the overall processing efficiency is extremely low.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Example:

[0023] like Figure 1-Figure 4 As shown, the utility model provides a special tooling for parts processing, including a seat body 1. The schematic diagram of the workpiece 3 is as shown Figure 4 As shown, it is tubular and has grooves on its surface along its length direction.

[0024] The seat body 1 is provided with a circular hole for accommodating the workpiece 3 along its length direction. This allows a number of workpieces 3 to be placed inside the circular hole along the direction of the circular hole. The diameter of the circular hole is equivalent to the outer diameter of the workpiece 3, so that the workpiece 3 can just fit inside the circular hole, and it also ensures that the workpiece 3 will not shake inside the circular hole. The surface of the seat body 1 is also provided with a processing groove 2 connected to the circular hole along its length direction, so that when the workpiece 3 is placed inside the circular hole, part of its surface is exposed to the bottom of the processing groove 2.

[0025] When the tooling for processing parts of the utility model is used, a plurality of tubular workpieces 3 to be processed are sequentially placed into the circular hole of the seat body 1, and then the circular hole is filled. Since the inner diameter of the circular hole is substantially the same as the outer diameter of the workpiece 3, the workpiece 3 is well positioned when placed. Then the seat body 1 is placed in the machine tool for processing. The tool of the machine tool extends from the processing groove 2, and then contacts the part of the workpiece 3 exposed in the processing groove 2 for processing.

[0026] This fixture can clamp several workpieces 3 at one time. At the same time, the round hole and the tubular workpiece 3 cooperate well, and the clamping efficiency is high.

[0027] In this embodiment, sealing plates 4 are detachably provided at both ends of the base body 1, so that the sealing plates 4 block both ends of the circular hole. The sealing plates 4 are connected to the base body 1 by screws, so that the sealing plates 4 can be disassembled and assembled as needed. The sealing plates 4 are provided with notches corresponding to the processing grooves 2, so that when the sealing plates 4 are covered on the base body 1, the notches are connected to the processing grooves 2, so that it is convenient for the tool to be inserted.

[0028] After the workpiece 3 is placed in the circular hole, the sealing plates 4 at both ends of the base body 1 can clamp the workpieces 3 inside the circular hole, thereby clamping the workpieces 3 in combination with the circular hole, thereby more effectively ensuring the processing stability and processing accuracy of the workpiece 3.

[0029] In this embodiment, the length of the circular hole is less than the total length of the workpieces 3 therein and the difference between the two lengths is 2-5 mm. This allows the workpieces 3 to be gradually clamped during the tightening of the two sealing plates 4 and remain attached to the workpieces 3 after clamping, thereby more effectively ensuring the stability of the workpieces 3.

[0030] In this embodiment, the workpiece 3 is tubular and includes a mandrel 5 that is inserted into the interior of the workpiece 3. The mandrel 5 is inserted into the interior of the workpiece 3. The sealing plate 4 is provided with a through hole 6 in cooperation with the mandrel 5, so that when the sealing plate 4 is covered at both ends of the base body 1, both ends of the mandrel 5 pass through a through hole 6 of the sealing plate 4.

[0031] When inserting the workpiece 3, a plurality of workpieces 3 can be firstly put into a string on the mandrel 5. Then, a string of workpieces 3 can be put into the circular hole as a whole, so as to improve the efficiency of inserting the workpiece 3.

[0032] In this embodiment, the processing groove 2 is formed on the upper surface of the base body 1. The end of the mandrel 5 and the hole wall of the through hole 6 are both arranged in a bevel shape so that the mandrel 5 is pressed upward during the tightening of the sealing plate 4. Figure 2 As shown. When the two sealing plates 4 gradually approach and clamp the workpieces 3, the hole wall of the hole 6 and the end of the mandrel 5 cooperate to press the mandrel 5 upward. As a result, the workpieces 3 are all pressed upward, ensuring the consistency of the clamping of the workpieces 3. It effectively ensures that the size of each workpiece 3 after processing is the same. At the same time, this also makes the workpiece 3 clamped more tightly and stably inside the round hole.

[0033] In practice, in order to put the workpiece 3 into the circular hole, the size of the circular hole must be slightly larger than the size of the workpiece 3. This makes the workpiece 3 shake inside the circular hole, which is not conducive to fine machining. The cooperation between the mandrel 5 and the hole wall through the hole 6 solves this problem very well.

[0034] In this embodiment, the base body 1 is provided with a step 7 below the sealing plate 4, so that the bottom of the sealing plate 4 is in contact with the surface of the step 7. During the clamping process of the sealing plate 4, the sealing plate 4 and the mandrel 5 interact with each other. The bottom of the sealing plate 4 contacts the step 7, so that the sealing plate 4 cannot move downward, thereby ensuring that the sealing plate 4 can effectively push the mandrel 5 upward.

[0035] In this embodiment, the hole wall of the circular hole is provided with a rubber pad 8. The rubber pad 8 has a buffering effect, and can protect the workpiece 3 and prevent the workpiece 3 from being worn. At the same time, the elasticity of the rubber makes the workpiece 3 fit well inside the circular hole, thereby preventing the workpiece 3 from rotating during the processing, and ensuring the processing accuracy.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
