Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, and more specifically, to a clamping device. Background Art

[0002] A car turbocharger is actually an air compressor that increases the air intake by compressing air. The turbine casing of the turbocharger needs to be polished and painted on the outer surface during processing, and a clamp is needed for extrusion and clamping during processing.

[0003] The existing announcement number is CN219484933U, and the name is a kind of automobile turbocharger housing processing device, which includes a processing table, two groups of vertical support legs are arranged on the processing table, and the two groups of support legs are provided with horizontal fixed shafts, and a rotating part is rotatably connected to the fixed shaft, and two symmetrical propulsion and telescopic mechanisms are arranged on the rotating part, and a rubber pad clamped on the surface of the turbocharger housing body is arranged on the propulsion and telescopic mechanism. A vertical guide plate is arranged on the processing table, and the guide plate is located between the two support legs. The top of the guide plate is provided with an arc-shaped card plate engaged in the positioning groove on the rotating part. By setting the fixed shaft, the rotating part, the guide plate, and the arc-shaped card plate, the position of the rotating part is changed by rotating the rotating part on the fixed shaft. The arc-shaped card plate is provided on the processing table. The clamping plate can be engaged in the positioning groove on the rotating part to position the rotating part after rotation. The rotation of the rotating part realizes the display of the upper and lower halves of the turbocharger housing body. The upper and lower parts of the turbocharger housing body can be processed separately without re-fixing the turbocharger housing body, thereby improving the convenience of clamping the turbocharger housing body processing and making the operation simpler. This solves the problem that the existing processing device needs to clamp, fix and disassemble the turbocharger housing at least twice when processing the upper and lower parts of the turbocharger housing body, resulting in relatively complicated clamping procedures during processing. This further simplifies the clamping and fixing operations of the automobile turbocharger housing processing device.

[0004] However, the above-mentioned clamped turbocharger housing has an arc-shaped clamping plate that is squeezed and clamped on the outer wall of the volute casing. In order to avoid the arc-shaped clamping plate affecting the processing of the outer wall of the volute casing, only half of the outer wall of the volute casing can be processed at a time, and then the clamping plate is flipped and switched to clamp the other plate before processing. Since the arc-shaped clamping plate is squeezed and clamped on the outer wall of the volute casing, the processing of the outer wall of the volute casing is blocked, and the processing of the outer wall of the volute casing cannot be completed at one time. Multiple processing and clamping takes a long time, which affects the efficiency of the volute casing processing. Utility Model Content
