Technical Field

[0001] The utility model belongs to the technical field of camshaft processing, and more specifically, particularly relates to a camshaft processing fixture. Background Art

[0002] The main body of the camshaft is a cylindrical rod with a length approximately the same as that of the cylinder group. It is equipped with multiple cams to drive the mechanical transmission parts of various parts. The camshaft needs to be rotated during processing.

[0003] Based on the above, the currently used fixtures need to be pre-punched for positioning, or positioned by a chuck and then rotated. The control of the chuck is difficult and requires tools to control. It lacks a feeding structure and lacks the function of quickly controlling the fixed clamping shaft and maintaining the rotation drive when fixed. Utility Model Content

[0004] In order to solve the above technical problems at least to a certain extent, the utility model provides a camshaft processing fixture.

[0005] The purpose and effect of the camshaft processing fixture of the utility model are achieved by the following specific technical means:

[0006] A camshaft processing fixture comprises a T-shaped base, with side guide rods fixedly arranged on both sides of the top of the T-shaped base; both sides of the top of the T-shaped base extend upward, and electric cylinders are fixedly arranged on the inner walls of the extension, and a sliding rotating frame is fixedly arranged at the telescopic end of the electric cylinder, and the sliding rotating frame slides outside the side guide rods; a thrust piston is fixedly arranged on the top of the protruding position of the T-shaped base, and a moving seat is connected to the telescopic end of the thrust piston; a rotating main shaft is rotatably arranged above the sliding rotating frame through a bearing; a hexagonal frame is fixedly arranged outside the rotating main shaft; and a control seat is fixedly arranged outside the sliding rotating frame.

[0007] Furthermore, the rotating spindle includes: a hexagonal guide rail, to which the adjacent ends of the rotating spindles on both sides are fixedly provided; a control piston, to which the other ends of the rotating spindles on both sides are fixedly connected; a spring is provided outside the telescopic end of the control piston, and the telescopic end of the control piston is rotatably provided in the sliding rotating frame in cooperation with a tapered roller bearing.

[0008] Furthermore, the hexagonal frame includes: a clamping piston, six groups of clamping pistons are fixedly arranged at the outer end of the hexagonal frame, and a clamping piece is fixedly arranged at the telescopic end of the clamping piston, and the clamping piece slides outside the hexagonal guide rail.

[0009] Furthermore, the control piston and the clamping piston are connected through the interior of the rotating main shaft and the hexagonal frame.

[0010] Furthermore, a movable rotating frame is slidably arranged above the control seat; a control screw is rotatably arranged above the control seat, and the control screw is threadedly connected to the movable rotating frame.

[0011] Furthermore, the control seat also includes: a drive motor, wherein a drive motor is fixedly arranged under a group of control seats, and the drive motor is connected to the rotating main shaft on the same side by a bevel gear transmission.

[0012] Furthermore, four groups of lifting pistons are fixedly arranged on the top of the movable seat, and two groups of supporting frames are fixedly arranged on the top of the four groups of lifting pistons; a cleaning rotating plate is rotatably arranged on one side of the movable seat; and a spring for automatic contraction is arranged inside the lifting piston.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The moving seat is set to provide the function of quickly moving the accessories to the appropriate height position. The hydraulic oil is input into the thrust piston to first expand the thrust piston and push the moving seat forward. Then the pressure is continued to expand the lifting piston to raise the carrier frame and the axle blank it supports. Conversely, due to the force of the spring in the lifting piston, the lifting piston contracts first and then the thrust piston contracts, thereby resetting the moving seat to avoid affecting the processing, thus realizing the function of automatic loading and unloading.

[0015] The clamping parts provide a combined function of fixing and rotating, drive the moving compression control piston of the mobile turntable, input the hydraulic oil in the control piston into the clamping piston, expand the clamping piston, and use the clamping parts to fix the shaft embryo to complete the fixation. The driving motor cooperates with the bevel gear to drive the rotating spindle to rotate, which can drive the shaft embryo to rotate as a whole for processing and achieve a stable transmission effect.

[0016] The cleaning turntable is provided to provide an obstacle-clearing function to ensure the movement of the moving seat. When the moving seat is pushed forward, the cleaning turntable will be used to push away the processed residues to ensure the normal movement of the moving seat and prevent the waste from getting stuck in the bottom pulley of the moving seat and affecting the movement.

[0030] The hexagonal frame 3 includes: a clamping piston 301 , six groups of clamping pistons 301 are fixedly arranged at the outer end of the hexagonal frame 3 , a clamping member 302 is fixedly arranged at the telescopic end of the clamping piston 301 , and the clamping member 302 slides outside the hexagonal guide rail 201 .

[0031] The control piston 202 and the clamping piston 301 are connected through the interior of the rotating main shaft 2 and the hexagonal frame 3 .

[0032] A movable rotating frame 401 is slidably disposed above the control seat 4 ; a control lead screw 402 is rotatably disposed above the control seat 4 , and the control lead screw 402 is threadedly connected to the movable rotating frame 401 .

[0033] The control seat 4 further includes: a driving motor 403, wherein a group of driving motors 403 are fixedly arranged under the control seat 4, and the driving motors 403 are connected to the rotating main shaft 2 on the same side by a bevel gear transmission.

[0034] Among them, four groups of lifting pistons 501 are fixedly arranged on the top of the moving seat 5, and two groups of supporting frames 502 are fixedly arranged on the top of the four groups of lifting pistons 501; a cleaning rotating plate 503 is rotatably arranged on one side of the moving seat 5; and a spring for automatic contraction is arranged inside the lifting piston 501.

[0035] like Figure 1-3 As shown, there is an extension pipe outside the propulsion piston 104, which needs to be connected to an oil pump. After the accessories are placed on the carrier 502, the hydraulic oil needs to be input into the propulsion piston 104 through the oil pump, and the propulsion piston 104 is first opened to push the moving seat 5 forward, and then the pressure is continued to increase to open the lifting piston 501, and the carrier 502 and the axle embryo supported by it are raised;

[0036] When the hydraulic oil in the lifting piston 501 and the pushing piston 104 is extracted, due to the action of the spring in the lifting piston 501, the lifting piston 501 contracts first and then the pushing piston 104 contracts, thereby resetting the moving seat 5 to avoid affecting the processing.

[0037] Embodiment 2:

[0038] On the basis of Example 1, Figure 1-6 As shown,

[0039] Start the electric cylinders 102 on both sides to bring the sliding turntable 103 and the rotating spindle 2 closer to wrap the two ends of the shaft embryo, then rotate the control screw 402 to drive the movable turntable 401 to move, and the movable turntable 401 moves to compress the control piston 202, and input the hydraulic oil in the control piston 202 into the clamping piston 301, open the clamping piston 301, and use the clamping part 302 to fix and clamp the shaft embryo, and then complete the fixation, start the drive motor 403 and cooperate with the bevel gear to drive the rotating spindle 2 to rotate, which can drive the shaft embryo to rotate as a whole for processing, and ensure that it can still rotate after the accessories are fixed.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In the utility model, when in use, the protruding position of the T-shaped base 1 is set at a position outside the machine tool, thereby enabling the camshaft to be installed outside the machine tool;

[0042] Place the accessory on the carrier 502, then input hydraulic oil into the push piston 104, first expand the push piston 104, push the moving seat 5, and then continue to increase pressure to expand the lifting piston 501, lift the carrier 502 and the axle embryo it carries;

[0043] Start the electric cylinders 102 on both sides to bring the sliding turret 103 and the rotating spindle 2 closer together, wrap the two ends of the shaft embryo, and then rotate the control screw 402 to drive the moving turret 401 to move. The movement of the moving turret 401 compresses the control piston 202, and the hydraulic oil in the control piston 202 is input into the clamping piston 301, which opens the clamping piston 301, and the shaft embryo is fixedly clamped by the clamping member 302, thereby completing the fixation;

[0044] At this time, the hydraulic oil in the lifting piston 501 and the pushing piston 104 is extracted. Due to the force of the spring in the lifting piston 501, the lifting piston 501 contracts first, and then the pushing piston 104 contracts, thereby resetting the moving seat 5 to avoid affecting the processing;

[0045] When rotation processing is required, the drive motor 403 is started to cooperate with the bevel gear to drive the rotation spindle 2 to rotate, so that the shaft embryo can be driven to rotate as a whole for processing;

[0046] After processing, when the movable seat 5 is pushed forward again, the cleaning rotating plate 503 is used to push away the processed residues to ensure the normal movement of the movable seat 5.
