Description

Technical Field

[0001] The utility model relates to the technical field of throttle valve press-fitting, in particular to a throttle valve press-fitting device. Background Art

[0002] The throttle is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it mixes with gasoline to become a combustible mixture, which then burns to produce work. The throttle is connected to the air filter at the top and the engine block at the bottom. It is called the throat of the car engine.

[0003] For example, a throttle pressing device with the authorization announcement number "CN220407791U" can rotate the throttle while fixing it in the pressing device, which reduces the workload of operators, saves time and effort, and improves work efficiency. It makes the replacement of the punch head more convenient for manual operation, saves workers' effort, saves time and effort, and improves work efficiency. However, the throttle is limited by the hydraulic cylinder in the above method. Since the connecting rod and the clamp are fixed in position, only the throttles at the same height can be limited, which has high limitations. At the same time, when the punch head needs to be replaced, the operator needs to push the punch head backward to drive the connecting block to move backward, and then push the two pressing blocks to slide in the slide groove to the round hole, and then push the pressing blocks to move in the opposite direction through the spring to fix the punch head. This operation is relatively cumbersome and increases manual labor and working time. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the throttle valves at the same height can only be limited due to the fixed positions of the connecting rod and the clamp, which has high limitations. At the same time, when the punching head needs to be replaced, the operator needs to push the punching head backward to drive the connecting block to move backward, and then push the two pressing blocks to slide in the slide groove to the round hole, and then push the pressing blocks to move in the opposite direction through the spring to fix the punching head. The operation is relatively cumbersome and also increases the problems of manual labor and working time, so a throttle pressing device is proposed.

[0009] Preferably, the first bevel gear and the second bevel gear are both rotatably connected to the inner wall of the third frame via a pin shaft, a second stud is fixedly connected to the surface of the second bevel gear, and an end of the second stud is rotatably connected to the inner wall of the third frame via a bearing.

[0010] Preferably, the second stud is threadedly connected to the two clamping plates, and the surfaces of the two clamping plates are slidably connected to the slideways processed on the surfaces of the third frame and the cross plate respectively.

[0011] Preferably, the throttle pressing and disassembly structure includes a hydraulic cylinder, which is fixedly connected to the inner wall of the bottom shell of the hydraulic cylinder, and the telescopic end of the hydraulic cylinder is fixedly connected with a threaded column, the threaded column is threadedly connected to a nut, a handle is fixedly connected to the surface of the nut, and the nut is threadedly connected to a raised part on the surface of the punch head.

[0012] The utility model proposes a throttle pressing device, which has the beneficial effect that: through the throttle pressing adjustment structure, the first motor is started to drive the first stud to rotate in the second frame through the bearing, the rotation of the first stud drives the two threaded seats to slide relative to each other in the slideway processed on the inner wall of the second frame, the relative sliding of the two threaded seats respectively drives the straight rods to move relative to each other, and the two relative activities drive the cross plate to slide upward in the slideways processed on both sides of the inner wall of the second frame, and the throttle pressing adjustment structure is added, so the height of the two clamping plates can be adjusted, which is suitable for pressing throttles of different heights and reduces limitations.

[0013] Through the throttle valve press-fit and disassembly structure, the hydraulic cylinder is controlled to drive the punch head to move to the two clamping plates, and the nut is turned upward by the handle. When the nut exceeds the protruding part of the punch head, the hydraulic cylinder is controlled to move upward to make the punch head separate from the threaded column and the nut. When the replaced punch head needs to be installed, the replaced punch head is inserted into the groove processed on the surface of the threaded column, and the nut can be installed by turning the nut. Using the throttle valve press-fit and disassembly structure, only the nut needs to be turned for replacement, which avoids the operator pushing the punch head backward to drive the connecting block to move backward, and then pushing the two pressing blocks to slide in the slide groove to the round hole, and then the spring pushes the pressing blocks to move in the opposite direction to fix the punch head. This operation is simple and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle:

[0029] Throttle valve press fitting and adjustment and punch head replacement work:

[0030] When the throttle valve needs to be press-fitted, the throttle valve is placed between the two clamping plates 11 of the first frame 5, and then the external power supply of the first motor 101 is turned on. The first motor 101 starts to drive the first stud 103 to rotate in the second frame 12 through the bearing. The rotation of the first stud 103 drives the two threaded seats 104 to slide relatively in the slideway processed on the inner wall of the second frame 12. The relative sliding of the two threaded seats 104 respectively drives the straight rod 102 to move relatively. The relative movement of the two 102 drives the cross plate 13 to slide upward in the slideways processed on both sides of the inner wall of the second frame 12, thereby driving the two clamping plates 11 at the upper end of the cross plate 13 to move upward. When the two clamping plates 11 move to the middle of the throttle valve, the first motor 101 stops rotating. In this way, the two clamping plates 11 can be adjusted. Then the external power supply of the second motor 9 is turned on. The second motor 9 starts to drive the first bevel gear 10 to rotate in the third frame 6. The rotation of the first bevel gear 10 can drive the second bevel gear 8 to rotate in the third frame 6.

[0031] The second stud 7 is rotated by the second bevel gear 8 to rotate in the third frame 6 through the bearing. The rotation of the second stud 7 drives the two clamping plates 11 to slide relatively in the slideways processed on the surfaces of the third frame 6 and the cross plate 13. In this way, the middle part of the throttle surface can be pressed and limited by the relative sliding of the two clamping plates 11. Then, the external power supply of the hydraulic cylinder 201 is turned on to drive the threaded column 202 and the punch head 4 to move downward to press the throttle surface. When the throttle is pressed and the punch head 4 needs to be replaced, the control The hydraulic cylinder 201 drives the punch head 4 to move to the two clamps 11, and then the nut 201 is turned upward through the handle 203. When the nut 204 exceeds the protruding part of the punch head 4, the hydraulic cylinder 201 is controlled to move upward to make the punch head 4 disengage from the threaded column 202 and the nut 204. When the replaced punch head needs to be installed, the protruding part of the replaced punch head is inserted into the groove processed on the surface of the threaded column 202, and the nut 204 is turned downward to overlap with the protrusion of the punch head and it can be installed. The punch head 4 can be replaced by this movement.
