Description

Technical Field

[0001] This utility model belongs to the technical field of engine assembly, and in particular to an automatic negative pressure oil suction fixture for the secondary reuse of engine oil pump components. Background Technology

[0002] In the field of automotive engine manufacturing and repair, TNGA series engines are widely used. After hot grinding, the oil pump parts of this series of engines often need to be reused, but the residual oil in the cavity must be removed before reuse.

[0003] Currently, the industry mainly uses manual methods for this process. Operators first plug the oil holes with sealant, then use an electric wrench to rotate the workpiece rotor to expel residual oil. However, this method has many drawbacks:

[0004] From a safety perspective, when the operator holds the workpiece, the workpiece is prone to shaking and rotating when the wrench is rotated, posing a safety hazard of the operator being pinched and pulled in, seriously threatening the personal safety of the workers.

[0005] From a health perspective, the repetitive actions of holding workpieces and operating wrenches for extended periods can cause fatigue in the fingers and wrists of operators, posing a risk of occupational diseases and increasing the company's labor costs and the health burden on employees.

[0006] From a production efficiency perspective, the process of installing the sealing plug and rotating the rotor currently takes an average of about 63 seconds per unit, which is relatively long and not conducive to large-scale, high-efficiency production. In addition, the residual oil that flows out needs to be cleaned a second time, which adds about 8.3 hours of working time per month. At the same time, it also requires additional consumption of auxiliary materials such as cleaning cloths and cleaning agents, costing up to 600 yuan per month, thus increasing production costs.

[0007] In summary, existing methods for cleaning residual oil from engine oil pump components pose safety hazards, health risks, low efficiency, and high costs, necessitating a better solution. Utility Model Content

[0008] In response to the problems mentioned above, this utility model proposes an automatic negative pressure oil suction fixture for the secondary reuse of engine oil pump components, the specific solution of which is as follows:

[0014] The workpiece sealing plug includes a sealing plug head, the sealing plug head is provided with a stop position, a through air pipe passes through the sealing plug head, and the end of the through air pipe is provided with an anti-detachment groove.

[0015] In one embodiment, in the negative pressure suction device, when the three-way pipe allows compressed air to flow from the air inlet to the exhaust outlet, a negative pressure environment is formed inside the vacuum chamber.

[0016] In one embodiment, the negative pressure port is connected to the worktable area of ​​the workpiece locking device via a pipe, and when the workpiece is fixed, it is aligned with the workpiece oil drain hole to draw in the discharged residual oil.

[0017] In one embodiment, in the workpiece locking device, the clamping block, driven by the locking handle, cooperates with the workpiece positioning pin to clamp the workpiece.

[0018] In one embodiment, the insertion depth of the workpiece sealing plug is limited by the stop position, and the through-hole air inlet is connected to a compressed air source.

[0019] In one embodiment, compressed air is input through the through-hole air pipe of the workpiece sealing plug to drive the internal rotor of the workpiece to rotate.

[0020] In one embodiment, the shape and style of the fixture are adapted to the workpiece structure of the TNGA series machine.

[0021] The beneficial effects of this utility model are:

[0022] 1. Eliminate potential safety hazards in the workplace;

[0024] 2. Significantly improves work efficiency;

[0025] The negative pressure suction device works in conjunction with the workpiece sealing plug to replace the manual oil draining process. Through the automated residual oil discharge and recycling design, the processing time of a single workpiece is greatly shortened.

[0026] 3. Reduce operating costs;

[0027] The negative pressure port directly draws residual oil into the oil collection box, eliminating the need for manual wiping and recycling, and avoiding secondary cleaning of residual oil, thus reducing labor hours and auxiliary material consumption.

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This utility model is described in detail.

[0041] Example 1:

[0042] like Figures 1-3 As shown, an automatic negative pressure oil suction fixture for the secondary reuse of engine oil pump parts includes a negative pressure suction device, a workpiece locking device, and a workpiece sealing plug.

[0043] The negative pressure suction device includes a bracket 101, a vacuum box 108 is provided above the bracket 101, a negative pressure port 107 is provided on the vacuum box 108, and an oil drain switch is provided at the bottom of the vacuum box 108, corresponding to the oil receiving box 102 located below the bracket 101.

[0044] The negative pressure port 107 is connected to the workpiece locking device area via a pipe;

[0045] The vacuum chamber 108 is also provided with a three-way pipe 109, which connects the air inlet 104 and the exhaust port 105. The air inlet 104 is connected to the air source switch 103, and the exhaust port 105 is equipped with a silencer 106.

[0046] The workpiece locking device includes a worktable 204, on which a workpiece positioning pin 203 and a clamping block 202 are provided. The locking handle 201 drives the clamping block 202 to move. A protective cover 205 is provided on the outside of the worktable 204.

[0047] The workpiece sealing plug includes a sealing plug head 301, the sealing plug head 301 is provided with a stop position 304, a through air pipe 302 passes through the sealing plug head 301, and the end of the through air pipe 302 is provided with an anti-detachment groove 303.

[0048] Working principle:

[0049] This invention utilizes a negative pressure suction device, a workpiece locking device, and a workpiece sealing plug in conjunction with each other. Compressed air is introduced into the workpiece through a through-hole air pipe 302 in the workpiece sealing plug to drive the rotor to rotate at high speed. The rotation of the rotor will squeeze residual oil inside the workpiece to the bottom oil drain hole for discharge. The protective cover 205 is used to cover the working area to prevent oil splashing or accidental contact of mechanical parts with the operator. The silencer 106 is used to reduce noise.

[0050] In use, after the air source switch 103 is activated, compressed air flows at high speed from the air inlet 104 to the exhaust port 105, and exchanges air with the air inside the vacuum chamber 108 through the three-way pipe 109, creating a negative pressure inside the chamber. The negative pressure port 107 uses the pressure difference to draw the discharged residual oil into the vacuum chamber 108, and then the oil drain switch of the vacuum chamber 108 discharges the residual oil to the oil collection box 102.

[0051] Among them, the workpiece positioning pin 203 and the clamping block 202 are designed to support interchangeability between different models; the negative pressure suction device can be independently applied to other oil suction scenarios, and the shape and style of the fixture are adapted to the workpiece structure of the TNGA series models.

[0052] Furthermore, in the embodiments, it can also be considered that in the negative pressure suction device, when the three-way pipe 109 allows compressed air to flow from the air inlet 104 to the exhaust port 105, a negative pressure environment is formed in the vacuum box 108.

[0053] Furthermore, in the embodiments, the negative pressure port 107 can be connected to the worktable 204 area of ​​the workpiece locking device through a pipe, so that when the workpiece is fixed, it is aligned with the workpiece oil drain hole to suck up the discharged residual oil.

[0054] Furthermore, in the embodiments, it can also be considered that in the workpiece locking device, the clamping block 202, driven by the locking handle 201, cooperates with the workpiece positioning pin 203 to clamp the workpiece.

[0055] In this embodiment, the workpiece positioning pin 203 ensures that the workpiece is in a preset position on the worktable 204, so that the oil drain hole at the bottom of the workpiece is strictly aligned with the suction pipe of the negative pressure port 107, ensuring that 100% of the residual oil is captured by the negative pressure port. During locking, the clamping stop 202 applies lateral pressure to the workpiece, forming a bidirectional clamping action with the workpiece positioning pin 203, preventing the workpiece from shaking or shifting during the following processes:

[0056] 1. Torque backlash during high-speed rotor rotation;

[0057] 2. Pipeline vibration during negative pressure oil suction;

[0058] 3. Airflow impact during compressed air input.

[0059] Furthermore, in the embodiments, the insertion depth of the workpiece sealing plug is limited by the stop position 304, and the input end of the through-type air pipe 302 is connected to a compressed air source.

[0060] Furthermore, in the embodiments, it can also be considered that the through-hole air pipe 302 of the workpiece sealing plug inputs compressed air to drive the internal rotor of the workpiece to rotate.

[0061] Furthermore, in the embodiments, the shape and style of the fixture can be adapted to the workpiece structure of the TNGA series machine.

[0062] The operating method of this utility model is as follows: Figure 4 , Figure 5 As shown, the specific steps include:

[0063] Step 1: Install the sealing plug

[0064] Insert the workpiece sealing plug into the uppermost oil inlet hole of the workpiece until the stop position 304 of the sealing plug head 301 abuts against the workpiece, ensuring a fixed insertion depth. Connect to a compressed air source with a pressure of 0.3 MPa through the through-hole air pipe 302;

[0065] Step 2: Fix the workpiece

[0066] Place the workpiece on the worktable 204 of the workpiece locking device, align the oil drain hole at the bottom of the workpiece with the workpiece positioning pin 203, and pull the locking handle 201 to drive the clamping block 202 to clamp the workpiece and prevent it from shaking.

[0067] Step 3: Start negative pressure suction

[0068] When the air source switch 103 of the negative pressure suction device is turned on, compressed air enters from the air inlet 104 and flows to the exhaust port 105 through the three-way pipe 109. At this time, a negative pressure environment is formed in the vacuum box 108, and the negative pressure port 107 generates suction.

[0069] Step 4: Residual Oil Recovery

[0070] The rotor inside the workpiece rotates under the drive of compressed air, and discharges residual oil from the bottom oil drain hole. The discharged oil is drawn into the vacuum box 108 by the negative pressure port 107 for temporary storage.

[0071] Step 5: End the operation

[0072] Turn off the air supply switch 103, and the negative pressure will disappear. Open the oil drain switch at the bottom of the vacuum box 108 to drain the engine oil into the oil collection box 102 for centralized recycling.

[0073] In practical applications, this invention reduces the processing time of a single workpiece to 35 seconds per unit, reduces residual oil cleaning time by 8.3 hours per month, saves auxiliary material costs of 600 yuan per month, and eliminates the disposal of 5 kg of hazardous waste contaminants per month, significantly reducing environmental compliance costs.

[0074] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
