Technical Field

[0001] The utility model relates to the technical field of hydraulic component application, in particular to a high-precision hydraulic cylinder earring and a processing fixture thereof. Background Art

[0002] Hydraulic cylinder earrings are one of the indispensable components in the hydraulic system. Their design and manufacturing quality directly affect the performance and safety of the entire system. Such earrings are usually made of high-strength materials to ensure stability and durability under high pressure and heavy load environments.

[0003] When cutting special-shaped earrings, they need to be clamped and fixed, but the original chuck jaws are too narrow and the clamping area is insufficient, which easily leads to insufficient friction, resulting in the movement of the workpiece earring during the cutting process, and then causing processing failure. Therefore, the utility model proposes a high-precision hydraulic cylinder earring and a processing fixture thereof. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-precision hydraulic cylinder earring and a processing fixture thereof. By using the original chuck groove, the original clamping claw is set to a contoured jaw, which increases the friction force and reduces the possibility of overturning. At the same time, in order to prevent the earring from rotating when cutting the hydraulic cylinder earring, a special core rod is added, which completely eliminates the risk of the earring rotating due to excessive cutting force.

[0007] Through the above technical scheme, the earring is first inserted into the positioning core rod through the internal ball ring, and then the external driving part squeezes the push column through the connected connecting column, thereby driving the rotating blocks on both sides to rotate inside the chuck through the rotating pin, and then driving the two moving blocks to slide inside the chuck, and finally the engaged clamping blocks cooperate with the auxiliary blocks at the bottom to tightly clamp and fix the placed earrings.

[0008] The utility model is further configured as follows: a protective cover plate is bolted to the front wall of the clamping disc.

[0009] The above technical solution facilitates the protection of the end face of the chuck to prevent workpieces or chips from falling into the interior of the chuck.

[0011] Through the above technical solution, the two rotating blocks can push the moving block under the action of the pushing column, so that the moving block can drive the clamping block to clamp and fix the earring.

[0012] The utility model is further configured as follows: the two clamping blocks are both connected with adjusting slide blocks through mounting groove bolts provided in the rear wall, and are respectively slidably connected to the inside of adjusting slide grooves provided in the two moving blocks through the two adjusting slide blocks.

[0013] Through the above technical solution, it is convenient to adjust the clamping block to a certain position inside the adjusting slide slot through the adjusting slider, so that it can be flexibly adjusted and fixed when clamping and fixing the earrings.

[0014] The utility model is further configured as follows: the opposing surfaces of the two clamping blocks and the moving block are correspondingly provided with engaging teeth B and engaging teeth A, and the clamping block and the moving block are tightly engaged with each other through the engaging teeth B and engaging teeth A under the action of bolt connection.

[0015] The above technical solution makes it easy to install the clamp block by using bolts and stably pressing and snapping the clamp block to connect it to the moving block, and facilitates disassembly and maintenance.

[0016] The utility model is further configured as follows: arc grooves fitting with the positioning core rod are arranged at the corners of the opposite surfaces of the two auxiliary blocks, and relatively protruding limiting parts are arranged at the corners of the opposite surfaces of the two clamping blocks.

A convex block 102a is fixedly connected to the outer wall of the connecting cylinder 102 near the end face position. A round hole 102b is penetrated through the middle of the convex block 102a.

[0031] As Figures 3 - 7As shown in the figure, a high-precision hydraulic cylinder earring processing fixture includes a fixture body 200. The fixture body 200 includes a chuck 201. A protective cover plate 201a is bolted to the front wall of the chuck 201, which is convenient for protecting the end face of the chuck 201 to prevent workpieces or chips from falling into the inside of the chuck 201. A push column 202 is smoothly attached to the inner wall of the chuck 201. A connecting column 203 is fixedly connected to the end face of the push column 202. Rotating blocks 204 are symmetrically and movably connected to both sides of the push column 202. Both rotating blocks 204 are rotatably connected to the inside of the chuck 201 through rotating pins 204a passing through the middle. And the two end faces of the two rotating blocks 204 are respectively movably connected to the inside of the movable groove A 202a symmetrically opened on the side of the push column 202 and the movable groove B 205a opened inside the two moving blocks 205. It can make the two rotating blocks 204 push the moving blocks 205 under the action of the push column 202, so that the moving blocks 205 can drive the clamping blocks 206 to clamp and fix the earrings. The other ends of the two rotating blocks 204 are both movably connected to moving blocks 205, and the two moving blocks 205 are both slidably connected to the positions near both sides inside the chuck 201. Bolts are bite-connected to the sides of the two moving blocks 205 away from the rotating blocks 204 with clamping blocks 206. Both clamping blocks 206 are bolted to adjusting sliders 206b through mounting grooves 206a opened on the rear walls, and are respectively slidably connected to the inside of adjusting sliding grooves 205b opened inside the two moving blocks 205 through the two adjusting sliders 206b, which is convenient for adjusting the clamping blocks 206 to a certain position inside the adjusting sliding grooves 205b through the adjusting sliders 206b, so as to flexibly adjust and fix them when clamping and fixing the earrings. Opposite surfaces of the two clamping blocks 206 and the moving blocks 205 are respectively provided with engaging teeth B 206c and engaging teeth A 205c. The clamping blocks 206 and the moving blocks 205 are tightly bite-connected through the engaging teeth B 206c and the engaging teeth A 205c under the action of bolt connection, which is convenient for installing the clamping blocks 206.

Auxiliary blocks 207 are bolted to the bottoms of the two clamping blocks 206. Arcuate grooves that fit the positioning mandrel 209 are provided at the corners of the opposite surfaces of the two auxiliary blocks 207. At the same time, relatively protruding limiting parts are provided at the corners of the opposite surfaces of the two clamping blocks 206. When clamping the earrings, the auxiliary blocks 207 can limit the position of the bottom of the earrings, and at the same time cooperate with the positioning mandrel 209 to stabilize the position. An installation block 208 is bolted to the front wall of the chuck 201 near the bottom. A positioning mandrel 209 is fixedly connected to the top of the installation block 208. First, the earring is sleeved on the positioning mandrel 209 through the inner spherical ring 101. Then, an external driving part squeezes the push column 202 through the connected connecting column 203, thereby driving the two rotating blocks 204 on both sides to rotate inside the chuck 201 through the rotating pins 204a.Then the two moving blocks 205 are driven to slide inside the clamping plate 201, and finally the clamping block 206 engaged with the auxiliary block 207 at the bottom tightly clamps and fixes the placed earrings.
