The processing fixture for the flat shell body is a device or tool used to ensure the processing accuracy and consistency of the shell body during the production process. The fixture plays a role of positioning, fixing, supporting and guiding in manufacturing.

[0003] The processing fixture can clamp the flat shell body quickly and reliably, reducing the time of manual adjustment and improving the processing efficiency. However, when using the processing fixture to clamp and position the flat shell body, due to uneven or unstable clamping force that may occur during the clamping process, the workpiece may be deformed during the processing, affecting the processing quality.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A processing fixture for a flat shell body, including a shell body. A processing fixture body is arranged at the bottom end of the shell body. The processing fixture body includes a processing base, a processing pedestal arranged directly above the processing base, and support columns symmetrically arranged in the middle of the processing pedestal and the processing base. The shell body is arranged at the top end of the processing pedestal. At the top end of the processing base, cylinders for clamping and positioning the shell body are symmetrically and fixedly installed. A connecting rod is arranged at the top end of the cylinder, and a clamping rod for clamping and positioning the shell body is arranged at one end of the connecting rod.

[0013] 2. Then, the housing body is placed in the middle of multiple limiting blocks. At this time, the staff starts the air cylinder to drive the clamping rod at one end of the connecting rod to move. When the clamping rod penetrates through the through groove at one end of the limiting block, the housing body will be quickly positioned.

[0024] Referring to Figures 1 to 6 , in the embodiment of the present utility model, a processing fixture for a flat shell includes a shell body 1. A processing fixture body 2 is arranged at the bottom end of the shell body 1. The processing fixture body 2 includes a processing base 21, a processing pedestal 22 arranged directly above the processing base 21, and support columns 23 symmetrically arranged in the middle of the processing pedestal 22 and the processing base 21. The shell body 1 is arranged at the top end of the processing pedestal 22. Symmetrically fixed and installed on the top end of the processing base 21 are cylinders 25 for clamping and positioning the shell body 1. A connecting rod 26 is arranged at the top end of the cylinder 25, and a clamping rod 27 for clamping and positioning the shell body 1 is arranged at one end of the connecting rod 26. A limiting component 3 for adjusting the clamping rod 27 is arranged at the top end of the processing pedestal 22. The limiting component 3 includes fixing grooves 31 symmetrically opened at the top end of the processing pedestal 22, limiting blocks 32 fixed inside the fixing grooves 31, and through grooves 37 opened at one end of the limiting blocks 32 for the clamping rod 27 to pass through. Limiting grooves 38 for limiting the clamping rod 27 are symmetrically opened inside the through grooves 37, and limiting rods 39 adapted to the limiting grooves 38 are symmetrically fixed at both ends of the clamping rod 27.

[0025] Referring to Figures 1 to 6, a fixing block 33 for facilitating adjustment inside the fixing groove 31 is fixedly installed at the bottom end of the limiting block 32, and locking rods 34 for locking with the fixing groove 31 are symmetrically inserted at the top end of the fixing block 33. A first friction gasket 35 for increasing the locking stability is fixedly installed at the bottom end of the locking rod 34. A second friction gasket 36 is arranged inside the fixing groove 31, and the friction direction of the second friction gasket 36 is opposite to that of the first friction gasket 35. One end of the clamping rod 27 is fixedly installed with a rubber cushion block 310 for reducing clamping deformation on one side close to the housing body 1. Embedding blocks 312 for facilitating replacement after wear are symmetrically fixedly installed at one end of the rubber cushion block 310, and embedding grooves 311 adapted to the embedding blocks 312 are symmetrically formed at one end of the clamping rod 27. A scale 313 for facilitating fine adjustment of the limiting block 32 by the staff is arranged at one end of the fixing groove 31.

[0026] Refer to Figures 1 to 6 , a fixing bolt 24 for fixing with the support column 23 is inserted at the top end of the processing pedestal 22, and the fixing bolts 24 are symmetrically inserted at the top end of the processing pedestal 22.

[0027] The working principle of the present utility model is as follows: When using the processing fixture body 2 to process the housing body 1, first, according to the size width of the housing body 1, the distance to be limited is adjusted through the scale 313, the fixing block 33 and the fixing groove 31. Then, the limiting block 32 is fixed at the top end of the processing pedestal 22 through the fixing groove 31 and the fixing block 33. After that, the locking rod 34 penetrates through the fixing block 33 to lock the fixing block 33 and the fixing groove 31. At the same time, the first friction gasket 35 and the second friction gasket 36 can increase the locking stability. Then, the housing body 1 is placed in the middle of multiple groups of limiting blocks 32. At this time, the staff starts the cylinder 25 to drive the clamping rod 27 at one end of the connecting rod 26 to move. When the clamping rod 27 penetrates through the through groove 37 at one end of the limiting block 32, the housing body 1 will be quickly positioned. When the clamping rod 27 passes through the through groove 37, the limiting rods 39 at both ends of the clamping rod 27 and the limiting grooves 38 inside the limiting block 32 will limit the elongation distance of the clamping rod 27, so that the elongation and clamping lengths of multiple groups of symmetric clamping rods 27 are kept consistent, reducing the situation that the housing body 1 is clamped and positioned deformed due to the clamping rod 27 being too long or too short, and increasing the stability and uniformity of the clamping and positioning. At the same time, the rubber cushion block 310 at one end of the clamping rod 27 can reduce the damage to the housing body 1 during clamping, increasing the safety of clamping and positioning the housing body 1. At the same time, when the rubber cushion block 310 is worn during later use, the rubber cushion block 310 can be quickly replaced only by removing the rubber cushion block 310 through the embedding block 312 and the embedding groove 311.
