Description

Technical Field

[0001] The invention relates to the technical field of plunger pump parts processing, in particular to an automatic pump bladder grinding machine and a use method thereof. Background Art

[0002] The working principle of a plunger pump is that the reciprocating motion of a plunger in a cylinder changes the volume of a sealed working chamber to achieve oil suction and pressure. The oil discharged by the plunger pump enters and exits through the waist-shaped holes in the oil distribution plate. Before a plunger pump is mass-produced, it undergoes repeated testing to achieve the expected output power. If the test results do not meet the expected performance, the plunger pump is disassembled to inspect the contact surface between the cylinder and the oil distribution plate, as well as the scratches on the oil distribution plate. Because the cylinder is usually made of copper and the oil distribution plate is made of steel, the oil distribution plate is harder than the cylinder. Therefore, the marks left by the cylinder on the oil distribution plate are not dents, but rather marks from the rotational friction of the material itself. The output power of a plunger pump is greatly affected by the fit between the cylinder and the oil distribution plate. Technicians can judge the fit by the depth of the scratches. Before reassembling the oil distribution plate into the plunger pump, it is ground to remove the scratches and reduce the thickness appropriately. After reassembly, further testing is carried out until the expected output power is achieved. Finally, the oil distribution plate is mass-produced with the thickness at this point, and the plunger pump is mass-assembled. However, currently, batch grinding of oil distribution plates is typically performed on a grinding machine. However, during the pilot phase, if individual oil distribution plates need to be ground, manual grinding is the only option. Manual grinding is not only inefficient, but also prone to fatigue after prolonged operation, resulting in reduced grinding accuracy. Therefore, there is an urgent need for an electric grinding device to improve grinding efficiency and accuracy. Summary of the Invention

[0036] The automatic pump gallbladder grinder needs to be installed and inspected before use to ensure that all parts of the equipment are firmly connected, the electrical circuits are correctly connected, and the motors can operate normally. Then you can operate it according to the following steps:

[0037] Preparation

[0038] The oil distribution plate to be ground is fixed with the oil distribution plate expansion fixture. Specifically, the expansion bolt 605 is passed through the tapered hole 601 in the middle of the expansion seat 604 and threaded into the locking cap 4. The expansion platform of different diameters at the bottom of the expansion seat 604 is then expanded and connected to the inner hole of the oil distribution plate to achieve a firm fixation of the oil distribution plate.

[0039] Each motor is adjusted to its initial state through the control button group 102. Based on the actual position of the oil distribution plate and the cylinder body and the grinding requirements, the control module in the control button group 102 is used to adjust the speed, direction, and operating time of the first motor, the second motor 207, the crank motor 503, and the lifting motor 206 to appropriate initial parameters, so that each component is in a ready-to-work state.

[0040] Installing and positioning the cylinder

[0041] The first motor is started, and the first motor drives the three-jaw chuck 105 connected to the output shaft. The three-jaw chuck 105 is used to fix the cylinder body in a suitable position, and the cylinder body protrudes upward through the circular hole in the middle of the operating table 104.

[0042] Depending on the relative height between the cylinder body and the oil distribution plate, the lifting motor 206 is activated via the control button assembly 102. The lifting motor 206 drives the lead screw 203 through the gear box 204 to rotate. The lead screw 203 drives the lifting rod 201 to slide within the lifting sleeve 2, thereby driving the support arm 210 and the oil distribution plate to adjust to the appropriate height, so that the oil distribution plate and the cylinder body are in the optimal grinding position, thereby improving grinding efficiency and quality.

[0043] Open drive and swing mechanism

[0044] When the second motor 207 is activated, it rotates the hexagonal connecting rod 303 via the universal joint 3. This, in turn, rotates the oil distribution plate due to the engagement of the locking cap 4 with the hexagonal inner sleeve 302. Because the output shaft of the second motor 207 is colinear with the central axis of the three-jaw chuck 105, the relative rotation of the oil distribution plate and the cylinder body is more precise, which helps improve grinding accuracy.

[0045] The crank motor 503 is activated, driving the first crank 506 to rotate. The first crank 506, in turn, rotates the second crank via the crank connecting shaft 505. Supported by the support member and the rotating shaft, the second crank drives the expansion seat 604 to swing back and forth along the Y-axis via the first and second support connecting rods 502 and the ball joint. This swinging motion creates a more complex relative motion between the oil distribution plate and the cylinder body, improving grinding uniformity and quality, and effectively compensating for the shortcomings of traditional mechanical grinding.

[0046] Grinding process

[0047] The oil distribution plate rotates continuously under the drive of the second motor 207, and at the same time swings back and forth along the Y-axis driven by the expansion seat 604 bracket driven by the crank mechanism, and the inner ring 501 can rotate around the X-axis so that the oil distribution plate can flexibly adjust the angle in this direction, thereby realizing multi-dimensional contact and grinding between the oil distribution plate and the cylinder grinding surface 801, ensuring the grinding effect.

[0048] During the grinding process, the operator can adjust the speed, direction, and operating time of the first motor, second motor 207, crank motor 503, and lift motor 206 at any time using the control button assembly 102, depending on the material of the oil distribution plate, the grinding requirements, and the actual grinding effect, to meet different grinding needs. For example, for oil distribution plates made of harder materials, the speed of the second motor 207 can be appropriately increased to increase the grinding speed; the lift motor 206 can be adjusted according to the relative position of the cylinder body and the oil distribution plate to maintain the optimal grinding height.

[0049] Finish work

[0050] After the grinding is completed, the second motor 207, the crank motor 503, the first motor and the lifting motor 206 are turned off in sequence.

[0051] The lifting motor 206 is controlled by the control button group 102 to lower the support arm 210 and the oil distribution plate to a suitable height for easy disassembly.

[0052] Remove the oil distribution plate from the expansion fixture, clean the automatic pump liner grinder, and perform routine inspection and maintenance on each component to prepare for the next use.
