DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-5As shown, the automobile piston aperture processing equipment provided by the utility model includes: a workbench 100, a turntable 200 is provided on the upper end of the workbench 100, a fixed table 300 is provided on the upper end of the turntable 200, and the inner end positioning groove 320 of the fixed table 300 is engaged and fixed with a clamping assembly 400, and the clamping assembly 400 includes: a threaded rotating rod 430, one end of the threaded rotating rod 430 is threadedly connected to an upper clamping block 450, and the upper clamping block 450 is a V-shaped structure, and a fixed block 460 is provided on the lower end surface of the upper clamping block 450, and the fixed block 460 is adapted to clamp the upper clamping block 450, and a polishing head 500 is provided on the upper end surface of the clamping center of the clamping assembly 400. Due to the differences in the sizes of the processed parts, In actual use, the staff places the part to be processed on the limit block 420 between the upper clamping block 450 and the fixed block 460, and then rotates the threaded rotating rod 430. Since one end of the threaded rotating rod 430 is fixed to the upper clamping block 450, the upper clamping block 450 is driven to move until the part to be processed is pressed against one end of the fixed block 460. After clamping and fixing, the internal aperture of the workpiece is processed by the polishing head 500. The clamping assembly 400 can be set to four groups, and according to the center of the turntable 200, the clamping assembly 400 is equally divided into four workstations. In this way, during operation, the four clamping assemblies 400 can clamp the workpiece at the same time, thereby improving work efficiency.

[0027] The clamping assembly 400 is provided so that piston parts of different models and sizes can be clamped and fixed, so that different pistons can be clamped during the processing. In actual use, the workpiece can be firmly supported through the cooperation of the upper clamping block 450 and the fixing block 460. During the processing, the stability of the workpiece is guaranteed. Compared with the existing limit groove clamping method, this device can clamp parts of different models, making it more applicable.

[0028] Second embodiment:

[0029] like Figure 5 As shown, a concave groove is provided at the end of the upper clamping block 450, and a guide column 440 is provided at one end of the concave groove. The upper clamping block 450 is slidably connected in the guide column 440, and the arc surface of the guide column 440 has the same arc as the concave groove. The arc surface set by the guide column 440 is the same as the concave surface on the end side of the upper clamping block 450. In actual use, when parts are being processed, clamping them in this way can provide a better positioning effect, prevent them from loosening during processing and affecting the processing accuracy, and reduce the displacement and deformation of the workpiece during processing.

[0030] Third embodiment:

[0031] like Figure 2As shown, the turntable 200 includes: a rotating disk 210, a limiting hole 240 is provided on the end face of the rotating disk 210, the lower end of the limiting hole 240 is engaged with a connecting block 230, and the lower end of the block 230 is connected to the motor spindle 220. When in use, the rotating disk 210 is sleeved on the outside of the motor spindle 220, and the motor spindle 220 is driven to rotate by a control switch, so that the rotating disk 210 can rotate synchronously with the motor spindle 220. In actual use, the operator can adjust and control the number of rotations of the motor spindle 220, and then complete the adjustment of the number of rotations of the rotating disk 210 under different speed controls, so as to better adapt to the operation time of different work steps and avoid the situation where the time is too short, thereby causing loose clamping.

[0032] By means of the adaptable fit between the set limiting hole 240 and the block 230, in actual use, the rotation of the motor main shaft 220 can better drive the rotating disk 210 to rotate, thereby avoiding idling between the motor main shaft 220 and the rotating disk 210. At the same time, the fit connection between the limiting hole 240 and the block 230, compared with the traditional welding fixation between the output end and the rotating disk, the fit connection can also change and replace the size of the rotating disk 210 according to different usage scenarios, thereby further increasing the practicality and applicability of the rotating disk 210.

[0033] Fourth example:

[0034] like Figure 1-3 As shown, a concave hole is provided on the upper end surface of the rotating disk 210, and a fixing platform 300 is installed on the upper end of the concave hole. The lower end of the fixing platform 300 is adapted to the size of the concave hole, and the fixing platform 300 is embedded and fixed in the concave hole. When the piston is performing aperture processing, debris will splash along with the rotation of the polishing head 500, which will affect the cleanliness of the table surface. In actual use, the fixed platform 300 is set to block the debris to the inside of the fixed platform 300, so as to avoid the polishing head 500 from splashing debris when rotating at a high speed. The fixing of the fixing platform 300 with the concave hole can facilitate the cleaning of the debris accumulated on the four walls of the fixing platform 300 after long-term use. Compared with the fixing method through rivets, this method can be faster and more convenient when cleaning the fixing platform 300.

[0035] Fifth embodiment:

[0036] like Figure 4 As shown, the fixed table 300 includes: a collection box 310, which is slidably connected in the fixed table 300. In actual use, the debris is pushed into the fixed table 300 through the fixed table 300, and some of the debris will fall to the lower end of the fixed table 300. The fallen debris can be collected by the set collection box 310. When the collection box 310 is full, the collection box 310 is pulled out from the fixed table 300 for cleaning.

[0037] Working principle: The staff places the workpieces to be processed in turn into the multiple groups of clamping assemblies 400 on the upper end of the limit table 410 for clamping. After the clamping is fixed, the polishing head 500 is started by the control switch to perform aperture processing on the workpieces clamped in one group of clamping assemblies 400. After one group is processed, the motor spindle 220 is started by the control button, and the workpieces in the other group of clamping assemblies 400 are rotated to the lower end of the polishing head 500 by the rotation of the rotating disk 210, and then processed again. The debris generated during the processing is collected in the collection box 310 inside through the fixed table 300.

[0038] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
