Description

Technical Field

[0001] This utility model relates to plunger assembly equipment and belongs to the field of automotive processing technology. Background Technology

[0002] When assembling a car, the plunger needs to be assembled first. The plunger mainly consists of a plunger rod, a spring, and a sleeve. During assembly, the spring needs to be sleeved on the plunger rod, the plunger rod with the spring sleeved is inserted into the sleeve, and one end of the plunger rod is flattened to prevent the sleeve from detaching from the plunger rod under the action of the spring force.

[0003] Since the plunger rod is a solid iron bar, a large clamping force is required when one end of the plunger rod needs to be flattened. Generally, the clamping force of the hydraulic cylinder is not enough to flatten the plunger rod.

[0004] Meanwhile, the spring needs to be compressed during the process of the plunger rod being flattened in order to expose one end of the plunger rod. Therefore, the risk factor of manual operation is high, and the force of manually pushing the plunger rod is uneven, which makes the plunger rod flattened in an inconsistent position. Utility Model Content

[0028] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0029] like Figure 1As shown, this utility model discloses a plunger assembly device, which includes a plunger rod clamping assembly 1, a positioning assembly 2, a first driving assembly 3, and a flattening assembly 4. The first driving assembly 3 is connected to the plunger rod clamping assembly 1. The plunger rod clamping assembly 1 is used to clamp the plunger rod at least as follows: Figure 4 As shown, the plunger rod clamping assembly 1 includes a first gripper 101 and a first gripper cylinder 102. The first gripper 101 is used to clamp the plunger rod at least once, and the first gripper cylinder 102 is used to drive the first gripper 101 to open or close. Under the drive of the first gripper cylinder 102, the first gripper 101 opens or closes, thereby clamping or releasing the plunger rod. Preferably, a second detection component is provided on one side of the first gripper 101. The second detection component is used to detect at least whether there is a plunger rod inside the first gripper 101. During operation, the plunger rod is placed into the first gripper 101 manually or by external equipment. When the second detection component detects that there is a plunger rod inside the first gripper 101, it sends a signal to the controller. The controller controls the first gripper cylinder 102 to drive the first gripper 101 to clamp, thereby clamping the plunger rod.

[0030] The positioning component 2 is used at least to fix the outer casing; the positioning component 2 is disposed on one side of the plunger rod clamping component 1; specifically, as shown in the figure Figure 3 As shown, the positioning component 2 includes a positioning block 201, and the positioning block 201 is provided with a contour hole 202 that matches the shape of the outer surface of the shell. Before assembly, the shell is placed into the contour hole 202 in the positioning block 201 by manual means or external equipment. Preferably, a first detection component is provided on one side of the positioning block 201, and a first through hole is provided on the positioning block 201. The first detection component can at least detect that the shell is provided in the positioning block 201 through the first through hole.

[0031] The first driving component 3 is at least used to drive the plunger rod clamping component 1 to move. After the plunger rod clamping component 1 clamps the plunger rod, the first driving component 3 drives the plunger rod clamping component 1 to move the plunger rod to the right and to the oil injection component 7. The oil injection component 7 injects oil into the spring on the plunger rod. During the assembly process, the first driving component 3 drives the plunger rod clamping component 1 to move to the left to insert the plunger rod into the inside of the housing and continues to push the plunger rod to move so that one end of the plunger rod extends out of the housing, making it easier to flatten one end of the plunger rod.

[0032] The flattening component 4 is disposed on the side of the positioning component 2 away from the plunger rod clamping component 1. The flattening component 4 is used at least to flatten one end of the plunger rod to assemble the plunger rod, spring, and housing together, and the positions of the plunger rod, spring, and housing are relatively fixed. Figure 2As shown, the flattening assembly 4 includes two pressing blocks 401. Each pressing block 401 has a guide groove 402. The two guide grooves 402 are inclined relative to each other. Each guide groove 402 contains a guide rod 403. A second driving assembly 404 is provided on one side of each guide rod 403. Both guide rods 403 are connected to the second driving assembly 404. Under the drive of the second driving assembly 404, the two guide rods 403 move along the guide grooves 402, so that the two pressing blocks 401 move closer or further apart, flattening one end of the plunger rod. The second drive assembly 404 includes a hydraulic cylinder or motor and a lead screw. In this embodiment, the second drive assembly 404 includes a hydraulic cylinder, the drive end of which is connected to a connecting seat. Both guide rods 403 are fixedly connected to the connecting seat. A fixed seat is provided on one side of the pressure block 401, and the two pressure blocks 401 are disposed within the fixed seat. The fixed seat prevents the pressure blocks 401 from moving up and down relative to the fixed seat. Under the drive of the second drive assembly 404, the two pressure blocks 401 can move closer or further apart. This application converts the up-and-down force driven by the hydraulic cylinder into a lateral clamping force that causes the two pressure blocks 401 to move closer or further apart, thus saving space in the equipment.

[0033] Preferably, the guide groove 402 is inclined at an angle of θ, where 0 < θ ≤ 45°. When θ = 45°, the ratio of the lateral clamping force of the pressure block 401 to the upward driving force of the cylinder is 1:1; when 0 < θ < 45°, the longitudinal stroke of the pressure block 401 is greater than the lateral stroke, therefore the lateral clamping force of the pressure block 401 is greater than the longitudinal driving force, and thus the ratio of the lateral clamping force of the pressure block 401 to the upward driving force of the cylinder is greater than 1, which can amplify the clamping force. Since the plunger rod is a solid iron rod, the existing cylinder cannot clamp the solid iron rod. The guide groove 402 inclined on the pressure block 401 in this application can increase the clamping force of the pressure block 401, enabling the solid iron rod to be flattened with a smaller force, saving driving force.

[0034] Because the plunger rod is constantly moved during use, friction is generated during this movement. To improve the service life of the handle, oil needs to be injected into the spring and plunger rod. Therefore, an oil injection component 7 is provided on one side of the plunger rod clamping assembly 1. The oil injection component 7 is used at least to inject oil into the spring. Specifically, the oil injection component 7 includes a second jaw 701. An oil passage hole is provided on the side wall of the second jaw 701. An oil pipe 703 is provided in the oil passage hole. An oil valve is provided on the oil pipe 703. When the oil valve is opened, the oil in the oil pipe 703 enters the second jaw 701 through the oil passage hole. A second jaw cylinder 704 is provided on one side of the second jaw 701. Under the drive of the second jaw cylinder 704, the second jaw 701 opens or closes. More specifically, the second gripper 701 is located below the plunger rod clamping assembly 1. In order for the second gripper 701 to clamp the spring, a third drive assembly 705 is provided below the second gripper cylinder 704. Under the drive of the third drive assembly 705, the second gripper 701 moves up and down, that is, moves closer to or away from the plunger rod clamping assembly 1.

[0035] When the spring and plunger rod need to be lubricated, the first drive assembly 3 drives the plunger rod clamping assembly 1, thereby driving the plunger rod and spring to move to the right, above the second gripper 701. The third drive assembly 705 drives the second gripper 701 and the second gripper cylinder 704 to move upward. At this time, the second gripper 701 is in the open state, and the plunger rod and spring are inside the second gripper 701. The second gripper cylinder 704 drives the second gripper 701 to close. At this time, the oil valve opens, and lubricating oil enters the spring and plunger rod through the oil pipe 703 and the oil passage. After the lubrication is completed, the second gripper 701 closes, and under the drive of the third drive assembly 705, the second gripper 701 moves downward.

[0036] In some implementation cases, such as Figure 5 As shown, the plunger assembly equipment also includes a fixed frame 5 and an outer cover 6. The plunger rod clamping assembly 1, positioning assembly 2, first drive assembly 3, and flattening assembly 4 are all mounted on the fixed frame 5. The outer cover 6 is located outside the plunger rod clamping assembly 1, positioning assembly 2, first drive assembly 3, and flattening assembly 4, and is slidably connected to the fixed frame 5. Specifically, the outer cover and the fixed frame 5 are slidably connected via a slide rail and a slider. Preferably, the fixed frame 5 is equipped with a sensor for detecting whether the outer cover 6 has moved into position. When the sensor detects that the outer cover 6 has moved into position, the first drive assembly 3, oil injection assembly 7, and flattening assembly 4 inside the outer cover 6 begin to work successively, which can ensure personal safety and improve the safety factor.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
