Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology; specifically, this utility model relates to a tooling fixture for hydraulic cylinder processing. Background Technology

[0002] Hydraulic cylinders have wide applications in industrial automation, machine tools, and construction machinery. For example, in industrial automated production lines, hydraulic cylinders can efficiently and accurately complete a variety of actions; in machine tools, hydraulic cylinders are commonly used in the operation of CNC machine tools, lathes, milling machines, and other machine tools to improve processing efficiency and accuracy; in construction machinery, hydraulic cylinders are mainly used in the operation of construction machinery such as excavators, bulldozers, and road rollers to provide powerful thrust and pull forces.

[0003] In the current technology for processing hydraulic cylinders, the cylinder barrel must first be placed inside a circular fixture, and then the fixture is adjusted. During the placement of the cylinder barrel, in order to avoid the cylinder barrel surface scraping against the positioning bolts, two workers are required to lift the cylinder barrel and insert it into the fixture in a suspended state. This is inconvenient to operate and is prone to scraping the cylinder barrel surface. Utility Model Content

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4 As shown, a typical embodiment of this utility model provides a tooling fixture for machining hydraulic cylinders, including: a collar 1, a cylinder barrel 2, a positioning bolt 3, a wheel frame 4, and a support roller 5; a base 1.1 is fixedly installed at the bottom end of the collar 1, the cylinder barrel 2 can be inserted into the collar 1, the support roller 5 is slidably installed in the collar 1 in the radial direction, and multiple sets of support rollers 5 are provided, each set of support rollers 5 has two, the wheel frame 4 includes a bracket 4.1 and a rotating frame 4.2, there are two rotating frames 4.2, the two rotating frames 4.2 are respectively rotatably installed at both ends of the wheel frame 4, the support roller 5 is set on the rotating frame 4.2, the positioning bolt 3 is set on the wheel frame 4, and the positioning bolt 3 is threadedly connected to the collar 1.

[0022] When machining the hydraulic cylinder, rotate the positioning bolt 3 to move the support roller 5 away from the center of the collar 1, insert the cylinder 2 into the collar 1, and make the bottom outer wall of the cylinder 2 contact the support roller 5. Push the cylinder 2 into the collar 1. At this time, the support roller 5 rotates, which makes it easier for the cylinder 2 to be inserted into the collar 1 more stably, so that the cylinder 2 can be stably installed in the collar 1. After the cylinder 2 is stably placed, rotate the positioning bolt 3 in the opposite direction, so that the positioning bolt 3 drives the wheel frame 4 to move towards the cylinder 2, so that the rotating frame 4.2 rotates, and the support roller 5 is locked, so that the cylinder 2 is stably clamped in the collar 1.

[0023] The collar 1 has grooves 1.2 on both sides. The two ends of the bracket 4.1 are inserted into the two grooves 1.2 respectively. The outer wall of the bracket 4.1 fits against the inner wall of the groove 1.2. The positioning bolt 3 passes through the center of the bracket 4.1.

[0024] When the bracket 4.1 is inserted into the groove 1.2, it can move stably towards the cylinder 2.

[0025] A limiting block 3.1 is fixedly installed on the outer wall of the positioning bolt 3. There are two limiting blocks 3.1, which are distributed vertically. The bracket 4.1 is set between the two limiting blocks 3.1. A spring 3.2 is fixedly installed on the top surface of the bracket 4.1. A rotating ring 3.3 is fixedly installed on the end of the spring 3.2 away from the bracket 4.1. Both the spring 3.2 and the rotating ring 3.3 are sleeved on the outside of the positioning bolt 3.

[0026] When the positioning bolt 3 moves, it can drive the limiting block 3.1 to move, so that the upper limiting block 3.1 drives the rotating ring 3.3 to move. When the rotating ring 3.3 moves, it can drive the bracket 4.1 to move. When the bracket 4.1 is limited by the cylinder 2 and cannot move, the positioning bolt 3 can continue to move, so that the spring 3.2 is compressed, so that the positioning bolt 3 can continue to move.

[0027] A sleeve 4.3 is fixedly installed at the top of the rotating frame 4.2. The sleeve 4.3 passes through the end of the bracket 4.1 and is rotatably installed at the end of the bracket 4.1. L-shaped connecting rods 3.4 are fixedly installed on the outer walls of both ends of the lower limiting block 3.1. The end of the connecting rod 3.4 away from the limiting block 3.1 is inserted into the sleeve 4.3.

[0028] When the positioning bolt 3 moves, it can drive the connecting rod 3.4 to move towards the sleeve 4.3.

[0029] The sleeve 4.3 has a threaded groove 4.4, and a sliding block 3.5 is fixedly installed on the outer wall of the end of the connecting rod 3.4 away from the limiting block 3.1. The sliding block 3.5 is slidably installed in the threaded groove 4.4.

[0030] When the bracket 4.1 can no longer move, the positioning bolt 3 continues to move, and the bracket 4.1 slides on the positioning bolt 3. At this time, the sleeve 4.3 can no longer move. When the limit block 3.1 moves, it drives the connecting rod 3.4 to insert into the sleeve 4.3. At this time, the sliding block 3.5 slides inside the threaded groove 4.4, causing the sleeve 4.3 to rotate and drive the rotating frame 4.2 to rotate, so that the support roller 5 can rotate and stably clamp the cylinder 2.

[0031] Both ends of the rotating frame 4.2 are provided with sliding grooves 4.5, and the opposite side of the sliding grooves 4.5 is connected with an extension groove 4.6. Both ends of the supporting roller 5 are fixedly installed with rotating shafts 5.1, gears 5.2 are fixedly installed on the rotating shafts 5.1, and a connecting ring 5.3 is sleeved on the outside of the rotating shafts 5.1.

[0032] When the support roller 5 moves relative to the rotating frame 4.2, the rotating shaft 5.1 can slide within the sliding groove 4.5, and the connecting ring 5.3 slides within the extension groove 4.6. When the rotating shaft 5.1 slides to the end of the sliding groove 4.5, it can lock the support roller 5. This makes the support roller 5 more stable when clamping the cylinder 2.

[0033] The rotating shaft 5.1 is slidably installed in the sliding groove 4.5, the connecting ring 5.3 is slidably installed in the extension groove 4.6, and the outer wall of the connecting ring 5.3 is fixedly installed with a spring 5.4. The end of the spring 5.4 away from the connecting ring 5.3 is fixedly installed on the inner wall of the extension groove 4.6.

[0034] When the rotating shaft 5.1 slides to the end of the sliding groove 4.5, it will compress the spring 5.4, so that the support roller 5 can move relative to the rotating frame 4.2.

[0035] Gear rings 4.7 are fixedly installed inside both ends of the rotating frame 4.2, and the gear rings 4.7 can mesh with the gear 5.2.

[0036] When the rotating shaft 5.1 slides to the end of the sliding groove 4.5, the gear 5.2 meshes with the gear ring 4.7, so that the support roller 5 can be locked when it moves relative to the rotating frame 4.2 and cannot rotate, making the support roller 5 more stable when clamping the cylinder 2.

[0037] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
