The abrasive belt polishing machine is used for processing, a deflector rod is required to be used when the abrasive belt polishing machine completes processing, the deflector rod and a polishing position are mutually interfered, one or more journals cannot be polished, a polishing procedure needs to be added, the processing cost is increased, and meanwhile the workpiece damage risk is increased.
Disclosure of Invention
The invention aims to provide a camshaft keyway driving polishing clamp, which overcomes the defects of the prior art, realizes the polishing of all shaft necks by clamping at one time, improves the production efficiency, reduces the production cost, improves the stability of the product quality and reduces the labor intensity of workers.
In order to achieve the purpose, the camshaft keyway driving polishing clamp comprises a clamp body, a positioning key and a fixing mechanism, wherein the clamp body comprises a positioning inner sleeve and a positioning outer sleeve, the positioning inner sleeve and the positioning outer sleeve are both round, the positioning inner sleeve is embedded into the positioning outer sleeve in an interference manner, a through hole is formed in any corresponding position of a round ring of the positioning inner sleeve and the positioning outer sleeve, the positioning key is arranged in the through hole, and the fixing mechanism is fixedly connected with the positioning outer sleeve through a supporting plate.
The fixing mechanism is composed of a supporting plate, a pull rod, a spring, an M5 hexagon socket head cap screw and an M6 hexagon socket head cap screw, wherein the upper portion of the supporting plate is arranged to be a rectangular cavity, two feet of the lower portion of the supporting plate are arranged to be arc-shaped, a through hole is formed in the middle of the upper portion of the rectangular cavity of the supporting plate, the spring is sleeved on the upper portion of a positioning key, the upper portion of the positioning key penetrates through the through hole in the middle of the supporting plate, then the positioning key is fixedly connected with the pull rod through the M5 hexagon socket head cap screw, the arc surface of the lower portion of the supporting plate corresponds to the outer circular surface of the positioning outer sleeve, and the positioning outer sleeve is fixed through the M6 hexagon socket head cap screw.
When the pull rod is lifted, the spring is sleeved on the positioning key to provide thrust in the opposite direction for the supporting plate and the positioning outer sleeve, and the spring is in a compressed state.
The fixing mechanism is characterized in that the lower end of the screw rod is fixedly connected with the positioning key, and the through hole in the positioning outer sleeve is a screw hole corresponding to the screw rod.
The positioning inner sleeve and the positioning outer sleeve are arranged to be concentric circles, the diameter of the outer circle of the positioning inner sleeve is larger than that of the inner circle of the positioning outer sleeve, the positioning inner sleeve is made of high polymer materials or organic materials, the positioning outer sleeve is made of metal materials, and a shifting fork is fixedly connected to the outer circle ring of the positioning outer sleeve at the end opposite to the through hole so as to be connected with a machine tool.
Compared with the prior art, the camshaft keyway driving polishing clamp has the following excellent effects.
According to the camshaft keyway driving polishing clamp, the camshaft is driven to rotate along with the clamp through the positioning key of the clamp, the clamp rotates along with the polishing machine in the forward direction and the reverse direction, forward rotation and reverse rotation required for polishing the camshaft journal are completed, the technical requirements of the process are met, the production efficiency is improved, the product quality stability is improved, the labor intensity of workers is reduced, the defects of multiple manual polishing procedures and low efficiency are overcome while the polishing quality of the camshaft is guaranteed, and the high cost input brought to enterprises by one additional procedure is avoided.
Drawings
FIG. 1 is a schematic view of a camshaft keyway drive buffing fixture of the present invention.
Wherein: 1. the positioning sleeve is an M5 inner hexagonal socket head cap screw, 2 is an M6 inner hexagonal socket head cap screw, 3 is a supporting plate, 4 is a positioning outer sleeve, 5 is a shifting fork, 6 is a pull rod, 7 is a spring, 8 is a positioning key, and 9 is a positioning inner sleeve.
Detailed Description
The camshaft keyway driving polishing jig of the present invention will be described in further detail with reference to the accompanying drawings.
The camshaft keyway drive polishing clamp shown in figure 1 comprises a clamp body, a positioning key 8 and a fixing mechanism, wherein the clamp body comprises a positioning inner sleeve 9 and a positioning outer sleeve 4, the positioning inner sleeve 9 and the positioning outer sleeve 4 are both designed to be circular, the positioning inner sleeve 9 is embedded into the positioning outer sleeve 4 in an interference manner, a through hole is formed in any corresponding position of a circular ring of the positioning inner sleeve 9 and the positioning outer sleeve 4, the positioning key 8 is arranged in the through hole, and the fixing mechanism is fixedly connected with the positioning outer sleeve 4 through a supporting plate 3.
The fixing mechanism is composed of a supporting plate 3, a pull rod 6, a spring 7, an M5 inner hexagonal socket head cap screw 1 and an M6 inner hexagonal socket head cap screw 2, the upper portion of the supporting plate 3 is set to be a rectangular cavity, two feet of the lower portion of the supporting plate 3 are set to be circular arc-shaped, a through hole is formed in the middle of the upper portion of the rectangular cavity of the supporting plate 3, the spring 7 is sleeved on the upper portion of a positioning key 8, the through hole in the middle of the supporting plate 3 penetrates through the upper portion of the positioning key 8, then the supporting plate 3 is fixedly connected with the pull rod 6 through the M5 inner hexagonal socket head cap screw 1, the circular arc surface of the lower portion of the supporting plate 3 corresponds to the outer circular surface of the positioning outer sleeve 4, and the M6 inner hexagonal socket head cap screw 2 is fixed on the positioning outer sleeve 4.
When the pull rod 6 is lifted up, the spring 7 is sleeved on the positioning key 8 to provide thrust in opposite directions for the support plate 3 and the positioning outer sleeve 4, and the spring 7 is in a compressed state.
