Description

Technical Field

[0001] The present invention relates to the technical field of pump accessory processing, and more particularly to an automatic grinding device for processing plunger pump accessories. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger slides and fits in the plunger hole of the plunger pump cylinder block to achieve the movement oil suction and movement oil discharge of the plunger hole. To achieve this state, it is necessary to ensure the tightness between the plunger and the plunger hole. Therefore, after the plunger pump cylinder block is manufactured, it is necessary to grind the inner wall of the plunger hole to ensure that the inner wall of the hole is smooth, so that the plunger and the plunger hole are tightly fitted. When grinding the plunger hole, there will be debris residue in the hole. At present, most of the existing grinding processing equipment can only perform grinding treatment on the plunger hole. Chinese Patent CN114770258B discloses an automatic grinding processing machine for plunger pump accessories, including a C-shaped plate. A rotating platform is rotatably installed on the upper end surface of the bottom of the C-shaped plate. The rotating platform is connected to an existing gap driving device. Four vertically distributed lifting lead screws are rotatably arranged between the two horizontal sections of the C-shaped plate, and the lifting lead screws are distributed at the corners of the horizontal section of the C-shaped plate. A linkage sprocket is installed at the top of the lifting lead screw. In this patent, the switching between the cleaning mechanism and the grinding mechanism is realized through a rotatable square bar. At the same time, the square bar is driven to rotate by an external driving device, and the cleaning mechanism and the grinding mechanism are driven to rotate by the square bar. After the switching is completed, the square bar is fixed by a pin shaft. Thus, after grinding the plunger hole, the debris in the plunger hole can be cleaned by the cleaning mechanism. However, this patent does not mention how the square bar is driven, and the square bar is fixed by a pin shaft. Due to the cooperation, the cleaning mechanism or the grinding mechanism may generate abnormal noises or vibrations during operation, thus affecting the final grinding accuracy of the plunger hole.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figures 1 to 8 As shown: an automatic grinding device for processing plunger pump accessories, including a frame 1, a mounting frame 12 and a flip frame 13, a horizontal support rod 11 is arranged at the bottom of the frame 1, the mounting frame 12 is fixedly connected to the support rod 11, and a gap is reserved between the frame 1 and the mounting frame 12 for the flip frame 13 to pass through; the flip frame 13 is arranged on the frame 1 so as to be rotatable around the support rod 11, the top and bottom of the flip frame 13 are respectively arranged with a cleaning head 132 and a grinding head 133, and a rotation driving component 123 for driving the cleaning head 132 and the grinding head 133 and a clutch control component 2 for controlling the clutch between the rotation driving component 123 and the cleaning head 132 and the grinding head 133 are arranged at the bottom of the mounting frame 12.

[0036] The frame 1 is a U-shaped structure. By rotating the flip frame 13, the flip frame 13 is rotated around the support rod 11. The rotation of the flip frame 13 drives the cleaning head 132 and the grinding head 133 located at the top and bottom thereof to switch, so that the cleaning head 132 and the grinding head 133 can be connected to the rotation drive component 123 respectively. The cleaning head 132 or the grinding head 133 is driven by the rotation drive component 123, thereby realizing the work of grinding the plunger hole of the plunger pump and cleaning it. During the rotation of the flip frame 13, the clutch between the rotation drive component 123 and the cleaning head 132 and the grinding head 133 is controlled by the clutch control component 2. The rotation drive component 123 is moved away from the cleaning head 132 and the grinding head 133, so that the cleaning head 132 and the grinding head 133 can be disconnected from the rotation drive component 123, and at the same time, the cleaning head 132 and the grinding head 133 on the flip frame 13 during the rotation process can be avoided. When the cleaning head After the switching of the cleaning head 132 and the grinding head 133 is completed, the clutch control component 2 is used to drive the cleaning head 132 or the grinding head 133 to be close to the rotating drive component 123, so that the rotating drive component 123 can transmit power to the cleaning head 132 or the grinding head 133, so that the grinding head 133 or the cleaning head 132 can operate the plunger pump. Through the above steps, while the cleaning head 132 and the grinding head 133 are switched, the cleaning head 132 and the grinding head 133 can be connected to the rotating drive component 123 respectively through the clutch control component 2, so that there is no need to equip the cleaning head 132 and the grinding head 133 with an independent driving source, which can reduce the overall cost of the equipment. Compared with the prior art method of fixing the flip frame 13 by a pin shaft, the stability of the equipment is higher, the abnormal noise generated by the cleaning head 132 and the grinding head 133 during operation can be reduced, and the grinding accuracy when grinding the plunger hole can be improved.

[0037] It should be noted that the frame 1 is installed on a mobile device, such as a manipulator or an operating table with lifting and level adjustment functions. The frame 1 is moved by such equipment, thereby driving the cleaning head 132 and the grinding head 133 on the frame 1 to operate on the plunger hole. There are many such devices, which will not be described one by one again.

[0038] like Figures 2 to 8 As shown: the rotation drive component 123 includes a driving shaft 1231 which is rotatable in a vertical state and is arranged at the bottom of the mounting frame 12, and the clutch control component 2 includes a first sliding frame 21 which can slide along the axial direction of the driving shaft 1231, and the first sliding frame 21 is provided with a first transmission shaft 211 which matches the driving shaft 1231, and the first transmission shaft 211 is sleeved on the driving shaft 1231 and slidably cooperates with it.

[0039] The rotary drive assembly 123 also includes a rotary drive motor 1232, which is fixedly connected to the interior of the mounting frame 12. The drive shaft 1231 is sleeved on the output shaft of the rotary drive motor 1232 and is transmission-connected thereto. By starting the rotary drive motor 1232, the output shaft of the rotary drive motor 1232 can drive the drive shaft 1231 transmission-connected thereto, and the rotation of the drive shaft 1231 drives the rotation of the first transmission shaft 211 connected thereto. When the drive shaft 1231 is required to transmit power to the cleaning head 132 or the grinding head 133, The sliding of the first sliding frame 21 drives the first transmission shaft 211 to slide on the driving shaft 1231. The driving shaft 1231 is preferably a hexagonal prism structure, so that the first transmission shaft 211 can maintain power transmission with the driving shaft 1231 while sliding on the driving shaft 1231. The rotation of the first transmission shaft 211 drives the rotation of the cleaning head 132 or the grinding head 133. The resetting of the first sliding frame 21 can drive the first transmission shaft 211 away from the cleaning head 132 or the grinding head 133, thereby disconnecting the power transmission and avoiding the rotating flip frame 13.

[0040] like Figures 2 to 8 As shown: a fixed shaft 121 coaxial with the driving shaft 1231 is arranged on the top of the mounting frame 12, and the fixed shaft 121 is fixedly connected to the mounting frame 12. The clutch control assembly 2 also includes a second sliding frame 22 which is mirror-symmetrical to the first sliding frame 21. The second sliding frame 22 is provided with a second transmission shaft 221 which can slide on the fixed shaft 121. The second sliding frame 22 can be slidably arranged on the top of the mounting frame 12 along the axial direction of the fixed shaft 121, and the sliding directions of the first sliding frame 21 and the second sliding frame 22 are opposite.

[0041] When the cleaning head 132 or the grinding head 133 is connected to the rotating drive assembly 123 through the rotation of the flip frame 13, the cleaning head 132 or the grinding head 133 at the other end of the flip frame 13 will rotate to the top of the fixed shaft 121. When the rotating drive assembly 123 drives the grinding head 133 and the cleaning head 132, the cleaning head 132 or the grinding head 133 located on the top of the mounting frame 12 is in a free rotating state. The grinding head 133 and the cleaning head 132 in operation may cause the cleaning head 132 or the grinding head 133 in a free rotating state to vibrate, which may cause damage to the cleaning head 132 or the grinding head 133, thereby causing abnormal sound or noise in the equipment. Since the sliding directions of the first sliding frame 21 and the second sliding frame 22 are opposite, when the first sliding frame 21 carries When the movable cleaning head 132 or the grinding head 133 is connected to the rotating drive assembly 123, the second sliding frame 22 can drive the second transmission shaft 221 to connect with the cleaning head 132 or the grinding head 133. The fixed shaft 121 is preferably a hexagonal prism structure. Since the fixed shaft 121 is fixedly connected to the mounting frame 12, the second transmission shaft 221 can only slide and cannot rotate. When the second transmission shaft 221 is driven by the second sliding frame 22 to the cleaning head 132 or the grinding head 133, the second transmission shaft 221 will drive the grinding head 133 and the cleaning head 132 to be fixed, thereby reducing the vibration generated by the cleaning head 132 or the grinding head 133 located at the top of the mounting frame 12, reducing the noise of the equipment, improving the stability of the equipment, and at the same time helping to improve the grinding accuracy of the grinding head 133 in operation.

[0042] like Figures 2 to 8 and Fig.10 As shown: the clutch control assembly 2 includes a swing shaft 23, a swing block 231 and two connecting rods 2311. The swing shaft 23 is a hollow structure. The swing shaft 23 is rotatably arranged on the side wall of the mounting frame 12, and the swing shaft 23 is sleeved on the support rod 11. The swing block 231 is sleeved on the swing shaft 23. One end of the two connecting rods 2311 is respectively hinged to the two ends of the swing block 231, and the other ends of the two connecting rods 2311 are respectively hinged to the first sliding frame 21 and the second sliding frame 22.

[0043] By rotating the swing shaft 23, the swing block 231 is driven to rotate by the rotation of the swing shaft 23, and the connecting rod 2311 hinged at both ends thereof is driven to move by the rotation of the swing block 231, and the first sliding frame 21 and the second sliding frame 22 are driven to move by the movement of the connecting rod 2311, so that the first sliding frame 21 and the second sliding frame 22 slide along the driving shaft 1231 and the fixed shaft 121 respectively, so that the first sliding frame 21 and the second sliding frame 22 can move synchronously, and the sliding directions of the two are opposite, thereby making one of the cleaning head 132 and the grinding head 133 connected to the rotating drive assembly 123, and the other can be fixed, thereby reducing the vibration generated by the cleaning head 132 or the grinding head 133 located at the top of the mounting frame 12, reducing the noise of the equipment, improving the stability of the equipment, and at the same time helping to improve the grinding accuracy of the grinding head 133 in operation.

[0044] There are preferably two swing shafts 23 and two swing blocks 231. The two swing shafts 23 are respectively located on both sides of the mounting frame 12. The two swing blocks 231 are respectively sleeved on the two swing shafts 23. The first sliding frame 21 and the second sliding frame 22 are driven by the connecting rod 2311 on the two swing rods, thereby further improving the stability of the first sliding frame 21 and the second sliding frame 22 during operation.

[0045] like Figures 2 to 8 As shown: the clutch control assembly 2 also includes a mounting plate 241, a rack 242 and a gear 232. The mounting plate 241 is slidable along the axial direction of the drive shaft 1231 and is arranged on the upper part of the interior of the mounting frame 12. The rack 242 is vertically fixedly connected to the bottom of the mounting plate 241. One end of the swing shaft 23 close to the mounting frame 12 passes through the side wall of the mounting frame 12. The gear 232 is sleeved on one end of the swing shaft 23 located inside the mounting frame 12, and the gear 232 is meshed with the rack 242.

[0046] The clutch control assembly 2 also includes a linear drive 25 and two positioning rods 24. The linear drive 25 is fixedly connected to the top end inside the mounting frame 12. The two positioning rods 24 are respectively located on both sides of the linear drive 25, and the two positioning rods 24 extend along the axial direction of the driving shaft 1231. The mounting plate 241 is sleeved on the two positioning rods 24 and slidably cooperates with them. The mounting plate 241 is transmission-connected to the linear drive 25. The linear drive 25 is preferably a cylinder. By starting the linear drive 25, the output shaft of the linear drive 25 can drive the mounting plate 241 transmission-connected thereto to slide along the axial direction of the positioning rod 24. The sliding of the mounting plate 241 drives the movement of the rack 242. The movement drives the rotation of the gear 232 meshing with it, and the rotation of the gear 232 drives the rotation of the swing shaft 23, and the rotation of the swing shaft 23 drives the rotation of the swing block 231, and the swing block 231 drives two connecting rods 2311, and the two connecting rods 2311 drive the first sliding frame 21 and the second sliding frame 22 respectively, so that one of the cleaning head 132 and the grinding head 133 is connected to the rotating drive assembly 123, and the other can be fixed, thereby reducing the vibration generated by the cleaning head 132 or the grinding head 133 located on the top of the mounting frame 12, reducing the noise of the equipment, improving the stability of the equipment, and at the same time helping to improve the grinding accuracy of the grinding head 133 in operation.

[0047] like Figures 2 to 7 As shown: the first sliding frame 21 and the second sliding frame 22 are both provided with two guide rods 212 parallel to the driving shaft 1231, and both ends of the flip frame 13 are provided with horizontal connecting plates 131, and the connecting plates 131 are provided with guide holes 1311 matching with the guide rods 212.

[0048] By setting the guide rod 212 and the guide hole 1311, when the clutch control component 2 drives the first sliding frame 21 and the second sliding frame 22 to move, in addition to driving the first transmission shaft 211 and the second transmission shaft 221, it also drives the movement of the guide rod 212, so that the guide rod 212 can be inserted into the guide hole 1311 of the connecting plate 131 of the flip frame 13, thereby guiding the sliding of the first sliding frame 21 and the second sliding frame 22, improving stability, reducing the vibration generated by the cleaning head 132 or the grinding head 133 located on the top of the mounting frame 12, reducing the noise of the equipment, improving the stability of the equipment, and at the same time helping to improve the grinding accuracy of the grinding head 133 in operation.

[0049] like Figures 2 to 8 As shown, the guide rods 212 are all elastic and retractable structures, and the ends of the guide rods 212 close to the guide holes 1311 are all cone structures.

[0050] In the process of the first sliding frame 21 and the second sliding frame 22 driving the guide rod 212 to insert into the guide hole 1311, the guide rod 212 may be offset, making it impossible for the guide rod 212 to be inserted into the guide hole 1311. By setting the cone structure, the slightly offset guide rod 212 can be corrected, so that the connection between the guide rod 212 and the guide hole 1311 is more stable, and the device has a certain fault tolerance rate.

[0051] As a result of the guide rod 212 being elastic and retractable, the guide rod 212 inserted into the guide hole 1311 can play a certain role in shock absorption and buffering, which can further reduce the noise of the equipment, improve the stability of the equipment, and help to improve the grinding accuracy of the grinding head 133 in operation. At the same time, it can also extend the service life of the guide rod 212 and avoid its direct rigid contact with components.

[0052] like Figures 2 to 8 and Fig.12 As shown, a first toothed disc 2111 is disposed on one end of the first transmission shaft 211 and the second transmission shaft 221 away from the mounting frame 12 , and a second toothed disc 1321 meshing with the first toothed disc 2111 is disposed on the cleaning head 132 and the grinding head 133 .

[0053] When the first sliding frame 21 drives the first transmission shaft 211 to move, the first transmission shaft 211 will drive the first toothed disc 2111 to approach the second toothed disc 1321 on the cleaning head 132 and the grinding head 133. When the first toothed disc 2111 and the second toothed disc 1321 abut, the first transmission shaft 211 can transmit power to the second toothed disc 1321, and drive the cleaning head 132 or the grinding head 133 to rotate through the second toothed disc 1321. Similarly, the second transmission shaft 221 can abut the second toothed disc 1321 through the first toothed disc 2111, so that the second toothed disc 1321 is fixed, thereby fixing the cleaning head 132 or the grinding head 133 flipped to the top of the mounting frame 12, thereby improving the stability of the equipment.

[0054] like Figures 2 to 12 As shown, a third toothed disc 111 which can slide along the axis direction is arranged on the swing shaft 23 , and a fourth toothed disc 134 which is meshed and connected with the third toothed disc 111 is arranged on the inner wall of the flip frame 13 .

[0055] The rotation of the swing shaft 23 can not only drive the swing block 231 to realize the synchronous and relative sliding of the first sliding frame 21 and the second sliding frame 22, but also drive the rotation of the flip frame 13 through the swing shaft 23. However, when driving the flip frame 13 to rotate, the swing block 231 needs to rotate first, and then drive the flip frame 13 to rotate, otherwise it will cause interference between the equipment parts. By setting the third toothed disc 111 that can slide along the axial direction of the swing shaft 23, in the initial state, the third toothed disc 111 and the fourth toothed disc 134 are away from each other, so that the swing shaft 23 can drive the first sliding frame 21 and the second sliding frame 22 to rotate. The movable frame 21 and the second sliding frame 22 are close to each other, so that the first transmission shaft 211 and the second transmission shaft 221 are respectively away from the cleaning head 132 and the grinding head 133. After the above steps are completed, the third gear disc 111 approaches the fourth gear disc 134 until the two are abutted, so that the rotating swing shaft 23 can transmit power to the fourth gear disc 134 through the third gear disc 111, and the fourth gear disc 134 drives the flip frame 13 to rotate one circle, so that the positions of the cleaning head 132 and the grinding head 133 at both ends of the flip frame 13 can be swapped, thereby realizing the switching of the cleaning head 132 and the grinding head 133.

[0056] like Figures 1 to 5 , Figures 7 to 12 As shown: a magnetic block 112 that can slide along the length direction of the support rod 11 is provided on the support rod 11, and the third toothed disc 111 is rotatably mounted on the magnetic block 112, and the third toothed disc 111 is transmission-connected to the swing shaft 23, and an electromagnet 122 that magnetically attracts and repels the magnetic block 112 is provided on the side wall of the mounting frame 12, and an elastic member 1121 is provided between the magnetic block 112 and the electromagnet 122.

[0057] The swing shaft 23 is provided with a guide groove 233 extending along its axis, and the third toothed disc 111 is provided with a guide strip 1111 matching the guide groove 233. In the initial state, the magnetic block 112 is located beside the electromagnet 122 by the setting of the elastic member 1121. At this time, the third toothed disc 111 and the fourth toothed disc 134 are away from each other. When the swing shaft 23 drives the first sliding frame 21 and the second sliding frame 22 to shrink, the electromagnet 122 is energized at this time, and the electromagnet 122 and the magnetic block 112 repel each other due to magnetic attraction, so that the magnetic block 112 drives the third toothed disc 111 to the fourth toothed disc 134 along the length direction of the support rod 11. The toothed discs 134 approach each other until the two are meshed, so that the swing shaft 23 can also drive the rotation of the flip frame 13, and the cleaning head 132 and the grinding head 133 are driven to switch through the flip frame 13. After the switching is completed, the power to the electromagnet 122 is disconnected, so that the magnetic suction block 112 is reset under the action of the elastic member 1121, so that the third toothed disc 111 and the fourth toothed disc 134 move away from each other and disconnect. It should be noted that the gear ratios of the third toothed disc 111 and the fourth toothed disc 134 are different, so that the swing shaft 23 can not only realize the movement of the first sliding frame 21 and the second sliding frame 22, but also drive the flip frame 13 to rotate.

[0058] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
