As shown in fig. 1, the workpiece 100 of the side long axis type includes a main body 101 and a shaft body 102, and the shaft body 102 is disposed on a side wall of the main body 101 and extends outward. When fixing the side long shaft type workpiece 100, it is necessary to fix the main body 101 and the shaft body 102 of the workpiece 100, and at the same time, it is necessary to ensure that the shaft body 102 does not deviate from the rotation center when the jig is rotated to process the outer periphery of the shaft body 102, which results in high difficulty in clamping the main body 101 and the shaft body 102, and difficulty in ensuring the processing precision.

The present embodiment provides a processing jig for fixing a workpiece 100 to be processed. As shown in fig. 2 and 3, the processing jig includes a fixing plate 1, a first fixing component 2 and a second fixing component 3. The first fixing assembly 2 comprises a pressing plate 21, the pressing plate 21 is detachably connected with the fixing plate 1, and the pressing plate 21 can fix the main body 101 to the fixing plate 1; the second fixing assembly 3 comprises a supporting member 31 and a clamp 32, the supporting member 31 is fixedly arranged on the fixing plate 1, the clamp 32 is detachably connected with the supporting member 31, and the clamp 32 can fix the shaft body 102 to the supporting member 31.

In this machining jig, the pressing plate 21 of the first fixing unit 2 can fix the main body 101 of the workpiece 100 to the fixing plate 1, the support 31 of the second fixing unit 3 can fill up the gap between the shaft body 102 and the fixing plate 1, and the clip 32 can fix the shaft body 102 to the support 31, so that the shaft body 102 can be kept stable with respect to the fixing plate 1.

The processing jig can fix the main body 101 and the shaft body 102 of the side long shaft type workpiece 100 on the fixed plate 1, ensure that the shaft body 102 cannot deviate from the rotation center in the process of rotating the processing jig, and improve the processing precision.

It will be appreciated that to ensure the stability of the workpiece 100 as a whole, it is first necessary to maintain the stability and positional accuracy of the body 101. As shown in fig. 2 and 3, to this end, the first fixing assembly 2 further comprises a fastening screw 22, the fastening screw 22 penetrating the pressing plate 21 and being screwed with the fixing plate 1. By connecting the fixing plate 1 with the fastening screw 22, the pressing plate 21 can firmly fix the main body 101 on the fixing plate 1, so that the main body 101 cannot relatively move with the fixing plate 1 in the processing process.

As shown in fig. 3, the pressing plate 21 is provided with a waist-shaped hole 211, and the fastening screw 22 is inserted through the waist-shaped hole 211 and is slidable in the longitudinal direction of the waist-shaped hole 211. It can be understood that the dimensions of the main body 101 of different workpieces 100 are different, so the distance between the pressing plate 21 and the main body 101 is also different, and the waist-shaped holes 211 are formed on the pressing plate 21 to adjust the relative positions between the pressing plate 21 and the fastening screws 22, so that the processing jig can be applied to workpieces 100 with various dimensions, thereby improving the applicability.

Preferably, a supporting groove 311 is concavely formed at one side of the supporting member 31, and the main body 101 is partially positioned in the supporting groove 311 and abuts against a sidewall of the supporting groove 311. The support groove 311 can ensure stability between the main body 101 and the support 31 by abutting against the main body 101, and the operator can determine a reference by the support groove 311 when installing the workpiece 100 to the processing jig, thereby improving efficiency.

As shown in fig. 1 to 3, the processing jig further includes a positioning pin 4, the main body 101 is provided with a fixing hole 1011, the fixing plate 1 is provided with a pin hole, the pin hole is opposite to the fixing hole 1011, and the positioning pin 4 can be inserted into the pin hole after passing through the fixing hole 1011. The fixing hole 1011 is a functional hole of the workpiece 100, and it is understood that the supporting slot 311 can only provide a reference of one dimension for the workpiece 100, and before the main body 101 is fixed by the pressing plate 21, the accuracy of the position of the main body 101 needs to be ensured. When the operator touches the main body 101 to the support groove 311, the accuracy of the position between the main body 101 and the fixing plate 1 can be greatly improved by inserting the positioning pin 4 into the fixing hole 1011 and the pin hole.

As shown in fig. 1, the main body 101 is provided with a plurality of fixing holes 1011, the fixing plate 1 is provided with pin holes corresponding to the fixing holes 1011 one by one, the processing jig comprises at least two positioning pins 4, and when the main body 101 is positioned, any two or more fixing holes 1011 can be selected to be inserted into the positioning pins 4 to finish positioning.

As shown in fig. 3 and 4, in order to secure the stability of the shaft body 102 during the machining process, the clip 32 includes a tightening portion 321 and two fixing portions 322 at both ends of the tightening portion 321, each fixing portion 322 being coupled to the supporting member 31 by a locking screw. The two fixing portions 322 can be connected to the supporting member 31 by the locking screw, so that the tightening portion 321 of the clip 32 can tighten the shaft body 102 to the supporting member 31, and stability between the shaft body 102 and the supporting member 31 is ensured.

As shown in fig. 4, the fixing portion 322 is provided with an adjustment through groove 323, the adjustment through groove 323 extends in the vertical direction, and the locking screw passes through the adjustment through groove 323 and is in threaded connection with the supporting member 31, and the locking screw can move in the adjustment through groove 323 in the vertical direction. For easy installation, when installing the workpiece 100 to the processing jig, the fixing plate 1 is in a horizontal state, so the adjusting through groove 323 extends along the vertical direction, and the clamp 32 can be adjusted according to the specific size of the shaft body 102, so that the processing jig can fix the workpieces 100 with different sizes of the shaft body 102, and the applicability of the processing jig is greatly improved.

Specifically, the adjustment through groove 323 penetrates to an end of the fixing portion 322 and forms an opening. Since the adjustment through groove 323 forms an opening at the end of the fixing portion 322, when the work 100 needs to be disassembled, the locking screw can be unscrewed, and then the clamp 32 can be separated from the supporting member 31 by moving the clamp 32 in the vertical direction, so that the work 100 is disassembled. Similarly, when the workpiece 100 is to be mounted, after the workpiece 100 is placed on the fixing plate 1, the clamp 32 may be directly moved downward to allow the locking screw to enter the adjustment through groove 323, and then the locking screw may be screwed.

The opening of the through groove 323 is adjusted so that the clip 32 can be separated from the supporting member 31 without the locking screw being separated from the supporting member 31 when the work 100 is mounted and dismounted, thereby improving efficiency and simplifying operation.

As shown in fig. 2 and 3, the second fixing assembly 3 further includes two adjusting members 33 slidably disposed on the supporting member 31, where the two adjusting members 33 are respectively located on two sides of the shaft body 102, and the two adjusting members 33 can approach each other and abut against the shaft body 102. The two adjusting members 33 can be abutted against the shaft body 102 on both sides to improve the stability of the shaft body 102, and the shaft bodies 102 with different sizes can be matched by adjusting the distance between the two adjusting members 33.

As shown in fig. 3, the end of the adjusting member 33 close to the shaft body 102 is inclined in the downward direction toward the direction away from the other adjusting member 33 to form a supporting surface 331, and the supporting surface 331 can abut against the shaft body 102. By using the inclined support surface 331 to abut against the shaft body 102, the surface of the shaft body 102 can be prevented from being scratched by the edges and corners, and the shaft body 102 can be supported, and the two support surfaces 331 and the support member 31 form three-point support for the shaft body 102, so that the stability of the relative position between the shaft body 102 and the support member 31 can be further improved.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
