Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a processing tool for a cylinder body. Background Art

[0002] like Figure 1 The cylinder body 10 shown is a precision mechanical component, which includes 9 plunger holes that fit closely with the plungers. The precision requirements of these holes are extremely high, and the challenges to the processing technology are quite large.

[0003] In addition, there is a kidney-shaped hole on the back of the cylinder body. The contact surface between this area and the oil distribution plate is crucial. Any slight damage may affect the overall performance. Therefore, crushing injuries must be strictly prohibited during the processing. In view of the wide application of cylinder bodies in mechanical equipment, their production batches are often large, which requires us to strive to improve processing efficiency while ensuring processing quality.

[0004] The prior art discloses a vertical processing device for a bevel axis motor control valve block, with a patent publication number of CN219234578U. The device realizes the positioning and clamping of the workpiece through a combination of a base plate, a positioning shaft, a spring, a screw, a nut, a pressure plate, a positioning block, a screw and a lifting eye screw. It can process multiple workpieces at a time, thereby improving the processing efficiency. In addition, the device also has the advantages of convenient loading and unloading and accurate positioning, and is suitable for mass production mode of one person and multiple machines.

[0005] However, although the existing technology has made some progress, there are still some shortcomings. For components with high precision requirements such as cylinder bodies, the existing tooling is not suitable in terms of positioning accuracy and clamping reliability. In addition, since the contact surface between the cylinder body and the oil distribution plate is particularly important, it is necessary to reduce the contact area between the tooling and the cylinder body to reduce the risk of crushing injuries. Therefore, there is an urgent need for a processing tooling with more accurate positioning, more reliable clamping, smaller contact area, and high efficiency suitable for mass production to meet the high standards and strict requirements of cylinder body processing.

[0009] Furthermore, the first positioning shaft, the second positioning shaft and the bottom of the circular groove are all provided with positioning holes, and cylindrical pins are provided in the positioning holes.

[0010] Furthermore, a positioning pin is screwed onto the top surface of the bottom of the second positioning shaft.

[0011] Furthermore, the first pressing block and the second pressing block are both T-shaped cylinders with a countersunk screw hole in the middle, and the edge of the top surface of the second pressing block is chamfered.

[0012] Furthermore, the diameter of the top of the first pressing block is larger than the diameter of the center hole at one end of the cylinder body, and the diameter of the bottom is the same as the diameter of the center hole of the cylinder body.

[0013] Furthermore, the diameter of the top of the second pressing block is larger than the diameter of the center hole at the other end of the cylinder body, and the diameter of the bottom of the second pressing block is the same as the diameter of the center hole at the other end of the cylinder body.

[0014] Furthermore, there are two rows of circular grooves in a longitudinal array on the base, and the first clamping device is arranged in one row of circular grooves, and the second clamping device is arranged in the other row of circular grooves.

[0016] Secondly, the clamping device adopts a combined structure of a positioning shaft, a clamping block and a bolt, so that the clamping block can be easily installed, adjusted and disassembled.

This not only improves work efficiency, but also reduces the difficulty of operation, making the processing process more convenient.

[0017] In addition, the overall stability and fixation are enhanced by the support columns and mounting holes. The setting of the support columns increases the supporting area of ​​the base and improves the stability of the tooling. The opening of the mounting holes facilitates the fixed connection between the tooling and the workbench or other equipment, prevents displacement during the processing, and improves the stability and safety of the processing process.

[0018] Finally, the design of the T-shaped cylinder enables the pressure block to withstand greater pressure. At the same time, the design of the countersunk screw hole and chamfer facilitates the installation and removal of the bolts and improves the convenience of operation. In addition, the cooperation between the pressure block and the cylinder body also ensures the uniform distribution of the clamping force, avoiding the risk of damage to the cylinder body due to uneven force.

[0019] Compared with the prior art, the utility model has the excellent effects of compact structure, convenient operation, high stability and high processing precision, can meet the needs of cylinder body processing, and improve processing quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
