Description

Technical Field

[0001] The utility model specifically relates to the technical field of automated clamp equipment, in particular to a clamp which is convenient for deburring the round edges of a cylinder valve surface. Background Art

[0002] As an important bearing in the hydraulic transmission system, the hydraulic cylinder has important technical parameters such as sealing performance and structural rigidity. The dimensional accuracy and surface quality requirements of the cylinder body are relatively high. Figure 5 The center of the cylinder body is set as a flat hole, and the end face is set in the positioning holes and threaded holes that match the other parts of the hydraulic system. The cylinder body valve face is a matching surface with extremely high roughness requirements. In the actual production process, burrs will appear on the rounded edges of the cylinder body valve face after milling. In order to remove the burrs on the surface and ensure that the cylinder body is based on the positioning reference and maintains the assembly accuracy required for design and production, we need to specially design a positioning clamping device for the cylinder body to maintain other surface quality and assembly requirements of the damaged parts during the deburring process. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that burrs exist on the round edges of the cylinder valve surface after milling in the background technology, and the surface burrs need to be removed, and the cylinder body needs to be based on the positioning reference to maintain the assembly accuracy required for design and production. We design a cylinder valve surface round edge deburring fixture.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A cylinder valve surface round edge deburring fixture, comprising a slide table, a telescopic cylinder, a rotating cylinder, a positioning plate and a clamping block arranged on a base.

[0006] An adjusting slider rail assembly is arranged between the slide and the base, which is used to adjust the left and right positioning position of the slide. A support plate is vertically arranged on the slide. A telescopic cylinder is horizontally connected to the rear end surface of the support plate. The telescopic rod of the telescopic cylinder passes through the central rotating table of the rotating cylinder which is also arranged on the front end surface of the support plate, and is connected to the clamping block through a bearing.

[0007] The center of the rotating table of the rotating cylinder is through-connected, and the clearance of the telescopic rod shaft hole of the telescopic cylinder is matched. The rotating table is coaxially connected with the positioning plate. The center of the positioning plate is through-connected, and the outer periphery is provided with a positioning end face that fits with the end face of the cylinder body to be positioned and clamped. A number of positioning pins are provided on the positioning end face. A rotating rod is arranged in position on the rotating table, and the rotating rod is fixedly connected to the clamping block. The rotating table is driven to rotate by the rotating cylinder, and the rotating table drives the clamping block to rotate synchronously and in the same direction through the rotating rod, so that the clamping block is rotated by a certain angle.

[0008] Furthermore, the outer peripheral contour of the clamping block is the same as the flat hole arranged at the center of the cylinder body, and the contour size is smaller than the inner diameter size of the flat hole.

[0009] Furthermore, after the clamping block is rotated by a certain angle, the long side can press the short side of the flat hole of the cylinder body, and the cylinder body is firmly pressed against the surface of the positioning plate.

[0010] Furthermore, the positioning pin cooperates with the positioning hole and the threaded hole on the end surface of the cylinder body to position the cylinder body.

[0011] Furthermore, the positioning plate is provided with a platform surface for avoiding deburring of rounded edges of the cylinder valve surface, so as to facilitate feeding or withdrawal of the brush.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The cylinder valve surface round edge deburring fixture utilizes a telescopic cylinder and a rotary cylinder to collaboratively realize the end face positioning and end face clamping of the cylinder body. The circumferential automatic extension and retraction of the central telescopic rod enables convenient loading and unloading of the cylinder body. The rotating table cooperates with the rotary rod to drive the clamping block to rotate, thereby achieving clamping and loosening of the cylinder body, which is practical and convenient.

[0022] See also Figure 1 An adjusting slider rail assembly is provided between the slide 1 and the base, which is used to adjust the left and right positioning position of the slide 1. A support plate 3 is vertically provided on the slide 1, and a telescopic cylinder 2 is horizontally connected to the rear end surface of the support plate 3. The telescopic rod 13 of the telescopic cylinder 2 passes through the central rotating table 5 of the rotating cylinder 4 which is also provided on the front end surface of the support plate 3, and is connected to the clamping block 7 through a bearing 11 to ensure that the clamping block can rotate freely around the telescopic rod.

The center of the positioning plate 6 is through-connected, and the outer periphery is provided with a positioning end face that fits with the end face of the cylinder body 9 to be positioned and clamped. A number of positioning pins are provided on the positioning end face. A rotating rod 10 is arranged on the rotating table 5 in a corresponding position. The rotating rod 10 is fixedly connected to the clamping block 7. The rotating table 5 is driven to rotate by the rotating cylinder 4. The rotating table 5 drives the clamping block 7 to rotate synchronously and in the same direction through the rotating rod 10, and the clamping block 7 is rotated by a certain angle so that the clamping block 7 is rotated to the point where the long side covers the short side of the cylinder body 9. After tightening the telescopic rod 13, the cylinder body 9 positioned on the positioning plate 6 is firmly pressed.

[0024] See also Figure 5 The outer peripheral contour of the clamping block 7 is the same as the flat hole 18 set in the center of the cylinder body 9, and the contour size is smaller than the inner diameter size of the flat hole 18.
