Description

Technical Field

[0001] This utility model belongs to the field of positioning device technology, specifically relating to a grinding and positioning fixture for rectangular water pump parts. Background Technology

[0002] Accessories refer to parts or components used in assembling machinery; they also refer to parts or components that are reinstalled after damage. Accessories can be divided into two categories: standard accessories and optional accessories. During the processing of accessories, grinding equipment is usually used to grind the surface of the accessories. During the grinding process, positioning devices are needed to fix the accessories so that they do not fall off or shift during grinding.

[0003] Patent CN217122744U discloses a fully adjustable part processing and polishing positioning device. It comprises a first cylinder, an electric polishing head, a translation adjustment mechanism, a rotary positioning mechanism, and two second cylinders. The device places a precision part between two clamping blocks. The two second cylinders extend synchronously, pushing the clamping blocks to hold the precision part in place and securely fix it. Then, the first cylinder extends, pushing the electric polishing head downwards to meet the precision part, initiating polishing. Simultaneously, the rotary positioning mechanism rotates the precision part, and the translation adjustment mechanism moves the part relative to the concave frame, displacing the precision part. This allows for comprehensive polishing of the precision part's outer surface, resulting in more thorough polishing, higher quality polishing, and faster efficiency. Furthermore, the device is highly automated, saving manpower and providing precise control.

[0004] When using the above-mentioned accessory grinding and positioning device, two cylinders are needed to drive two clamping blocks to clamp and position the two sides of the accessory. The two cylinders increase the application cost of the equipment, and in order for the two cylinders to meet the synchronization requirements of starting and stopping, other equipment is required to cooperate, which further increases the cost. Utility Model Content

[0005] Existing grinding and positioning devices for parts require two cylinders to drive two clamping blocks to clamp and position the parts on both sides. The use of two cylinders increases equipment application costs, and achieving synchronous start-stop operation of the two cylinders requires additional equipment, further increasing costs. This invention provides a grinding and positioning fixture for rectangular water pump parts. Simply rotating the rotating base in place drives the moving base to move the two positioning blocks to position the part. Compared to the traditional two-cylinder setup, this reduces equipment application costs and eliminates the need for the synchronized start-stop conditions and costs of two cylinders. The part positioning process is simple and easy to operate, better meeting the needs of parts grinding and positioning. The specific technical solution is as follows:

[0006] A grinding and positioning fixture for a rectangular water pump accessory includes a base. A positioning plate is installed at the lower left corner of the base. The positioning plate is L-shaped, and one side of the accessory is positioned on the L-shaped sidewall of the positioning plate. A movable seat is movably provided at the upper right corner of the base. A sliding groove is formed through the outer wall of the movable seat, and the central axis of the sliding groove coincides with the diagonal of the base. A fixing pin is vertically installed on the outer wall of the base, and the sliding groove is slidably fitted onto the outer wall of the fixing pin. A housing is installed on the movable seat near the outer wall of the accessory. Two connecting blocks are slidably embedded in the outer wall of the housing. Each of the two connecting blocks is equipped with a positioning block, and the two positioning blocks are respectively attached to the other side of the accessory. The accessory is positioned by the combined action of the positioning plate and the two positioning blocks.

[0007] In the above technical solution, a rotating seat is rotatably provided on the outer wall of the base. The side of the rotating seat near the outer wall of the movable seat is set as a smooth arc shape, and the smooth arc outer wall of the rotating seat is rotatably attached to the outer wall of the movable seat.

[0008] In the above technical solution, a handle is vertically installed on the side of the rotating seat away from the outer wall of the movable seat.

[0009] In the above technical solution, a first positioning pin is installed on the outer wall of the movable seat, a second positioning pin is installed on the outer wall of the rotating seat, and tension springs are hung on the outer walls of the first positioning pin and the second positioning pin.

[0010] In the above technical solution, the cross-sectional shape of the fixing pin is set to T-shape.

[0011] In the above technical solution, a through groove is provided on the lower left side wall of the housing, a screw is rotatably connected to the inner cavity of the housing, and the outer walls of the screw are provided with threads of opposite directions and symmetrically arranged on both sides. The two connecting blocks are respectively threaded onto the outer walls of the screw, and the connecting blocks are slidably embedded in the inner cavity of the through groove.

[0012] In the above technical solution, one end of the screw extends out of the outer wall of the housing and is connected to an adjusting block.

[0013] In the above technical solution, fixing blocks are installed at the four corners of the side wall of the base, and positioning holes are opened through the outer wall of each fixing block.

[0014] In the above technical solution, the outer wall of the housing is provided with multiple insertion holes, and the multiple holes are equidistantly arranged around the screw in the circumferential direction. The outer wall of the adjusting block is provided with a insertion rod, and the free end of the insertion rod is embedded in the inner cavity of one of the insertion holes.

[0015] The present invention provides a grinding and positioning fixture for rectangular water pump parts, which, compared with the prior art, has the following advantages:

[0016] I. Existing parts grinding and positioning devices require two cylinders to drive two clamping blocks to clamp and position the parts on both sides. The use of two cylinders increases the equipment application cost, and to meet the synchronous start and stop requirements of the two cylinders, other equipment is needed to further increase the cost. This utility model can position one side of the part by setting a positioning plate, and the other side of the part can be positioned by the cooperation of two positioning blocks. This utility model only needs to drive the rotating seat to rotate in place, which can drive the moving seat to move the two positioning blocks to position the part. Compared with the traditional two-cylinder setup, it reduces the equipment application cost and eliminates the need to consider the matching conditions and costs of synchronous start and stop of two cylinders. The parts positioning steps are simple and easy to operate, which better meets the needs of parts grinding and positioning.

[0017] II. This utility model, through the cooperation of the rotating seat, the second positioning pin, the tension spring, and the first positioning pin, can cause the moving seat to move along the outer wall of the fixed pin, and cause the positioning block on the outer wall of the moving seat to move closer to or further away from the outer wall of the accessory, thus freely realizing the flexible positioning or disassembly of the accessory.

[0018] Third, by means of the first positioning pin, the second positioning pin and the tension spring, this utility model can automatically realize the movement seat and the positioning block detaching from the outer wall of the part when the rotational force on the rotating seat is removed, and realize the automatic reset of the positioning block without the need for additional steps, saving the operation time when grinding and positioning parts in batches.

[0019] Fourth, by means of the cooperation of the housing, through groove, screw, adjusting block and connecting block, this utility model can adjust the relative distance between the two positioning blocks, thereby enabling the two positioning blocks to be suitable for the positioning needs of accessories of different shapes, and making the application range of the positioning device wider.

[0020] In summary, this utility model only requires driving the rotating seat to rotate in place, which in turn drives the moving seat to move the two positioning blocks to position the parts. Compared with the traditional setup of two cylinders, it reduces the equipment application cost and eliminates the need to consider the matching conditions and costs of synchronous start and stop of two cylinders. The part positioning process is simple and easy to operate, which better meets the needs of part grinding and positioning. It also allows for adjustment of the relative distance between the two positioning blocks, thereby enabling the two positioning blocks to be used for positioning needs of parts with different shapes, thus making the positioning device more widely applicable.

Detailed Implementation

[0027] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] The existing parts grinding and positioning device requires two cylinders to drive two clamping blocks to clamp and position the parts on both sides. The use of two cylinders increases the equipment's application cost, and to ensure the two cylinders can start and stop synchronously, other equipment is needed, further increasing costs. (See [reference needed]). Figures 1 to 3 As shown, a grinding and positioning fixture for a rectangular water pump accessory includes a base 1. Fixing blocks 18 are installed at the four corners of the side wall of the base 1. Each fixing block 18 has a positioning hole 19 extending through its outer wall. By passing bolts through the positioning holes 19, the fixing blocks 19 are connected to other devices, thereby enabling flexible installation and connection between this positioning device and other equipment. A positioning plate 2 is installed at the lower left corner of the base 1. The positioning plate 2 is L-shaped. (See reference...) Figure 1As shown, the positioning plate 2 consists of two mutually perpendicular plates forming a right angle to facilitate subsequent positioning of one corner of the accessory. The L-shaped sidewall of the positioning plate 2 positions one side of the accessory 3, meaning the lower left corner of the accessory 3 is positioned at the right angle of the positioning plate 2, thus achieving initial positioning of the lower left corner of the accessory 3. A movable seat 7 is movably mounted on the upper right corner of the base 1. A sliding groove 8 is formed through the outer wall of the movable seat 7, and the central axis of the groove 8 coincides with the diagonal of the base 1. A fixing pin 6 is vertically installed on the outer wall of the base 1, and the sliding groove 8... The movable seat 7 is slidably sleeved on the outer wall of the fixed pin 6. Under the action of external force, the movable seat 7 can move along the outer wall of the fixed pin 6. Under the limiting action of the sliding groove 8, the movable seat 7 is ensured to move along the outer wall of the fixed pin 6. A housing 12 is installed on the side of the movable seat 7 near the outer wall of the accessory 3. Two connecting blocks 16 are slidably embedded in the outer wall of the housing 12. Positioning blocks 17 are respectively installed on the two connecting blocks 16. The two positioning blocks 17 are respectively attached to the other side of the accessory 3. The accessory 3 is positioned by the combined action of the positioning plate 2 and the two positioning blocks 17. See reference Figure 3 As shown, the cross-sectional shape of the fixing pin 6 is set to T-shaped, thereby ensuring that the moving seat 7 will not slip off the outer wall of the fixing pin 6 when it moves along the outer wall of the positioning pin 6.

[0029] Under the action of external force, the movable seat 7 moves along the outer wall of the fixed pin 6 to the lower left corner, so as to drive the housing 12, the connecting block 16, and the positioning block 17 to move synchronously to the lower left corner until the outer wall of the positioning block 17 is clamped and positioned with the upper right corner of the accessory 3. Under the cooperation of the positioning plate 2 and the two positioning blocks 17, the accessory 3 is positioned on the upper surface of the base 1.

[0030] See Figure 2 As shown, a rotating seat 4 is rotatably mounted on the outer wall of the base 1 via a bearing. The side of the rotating seat 4 closest to the outer wall of the movable seat 7 is designed as a smooth arc, and the smooth arc outer wall of the rotating seat 4 rotates and fits against the outer wall of the movable seat 7. Therefore, the rotating seat 4 causes the movable seat 7 to move to the lower left corner along the outer wall of the fixed pin 6. A handle 5 is vertically mounted on the side of the rotating seat 4 away from the outer wall of the movable seat 7. The handle 5 makes it easier to drive the rotation of the rotating seat 4. A first positioning pin 9 is mounted on the outer wall of the movable seat 7, and a second positioning pin 10 is mounted on the outer wall of the rotating seat 4. A tension spring 11 is hung on the outer wall of the first positioning pin 9 and the second positioning pin 10. The tension spring 11 is a commonly used tension spring on the market. It can produce elastic deformation when subjected to external force and can return to its initial state after the external force is removed.

[0031] When the rotating seat 4 drives the moving seat 7 to move, it causes the tension spring 11 hanging on the outer wall of the first positioning pin 9 and the second positioning pin 10 to undergo elastic deformation. When the rotational force on the rotating seat 4 is removed, the moving seat 7 and the positioning block 17 are automatically disengaged from the outer wall of the accessory 3 by means of the elastic force of the tension spring 11, and the positioning block 17 is automatically reset without the need for additional steps, saving operation time when grinding and positioning a batch of accessories.

[0032] See Figure 2 As shown, a through groove 13 is provided on the lower left side wall of the housing 12. A screw 14 is rotatably connected to the inner cavity of the housing 12. The screw 14 is a commercially available mature model screw, and its thread helix angle is less than or equal to the friction angle between the thread material and the contact surface material. This ensures that the screw 14 can achieve self-locking when it is not rotating. This is existing technology. One end of the screw 14 extends out of the outer wall of the housing 12 and is connected to an adjusting block 15. By driving the adjusting block 15 with a tool, the screw 14 can be rotated, which makes it easier to achieve the rotation of the screw 14. The outer wall of the screw 14 is provided with threads of opposite directions and symmetrical. Two connecting blocks 16 are respectively threaded on both sides of the outer wall of the screw 14, and the connecting blocks 16 are slidably embedded in the inner cavity of the through groove 13.

[0033] When the shape or size of accessory 3 changes, the screw 14 is rotated by driving the adjusting block 15, causing the two connecting blocks 16 to move along the outer wall of the screw 14 and the inner cavity of the through groove 13, thereby adjusting the distance between the two positioning blocks 17 to adapt to the positioning requirements of accessory 3 in different situations.

[0034] Multiple insertion holes 20 are provided on the outer wall of the housing 12, and the multiple holes 20 are equidistantly arranged circumferentially around the screw 14. An insertion rod 21 is provided through the outer wall of the adjusting block 15, and the free end of the insertion rod 21 is embedded in the cavity of one of the insertion holes 20. When the adjusting block 15 is driven to rotate, by inserting the insertion rod 21 into the cavity of one of the corresponding insertion holes 20, the adjusted block 15 can be stably limited after rotation, thereby ensuring that the screw 14 will not rotate again after rotation. Combined with the self-locking function of the screw 14 itself, it can be ensured that after the screw 14 rotates, even under vibration and other loads, the screw 14 of this solution can be mechanically locked by the insertion of the insertion rod 21 into the cavity of the insertion hole 20.

[0035] This invention only requires driving the rotating seat 4 to rotate in place, which in turn drives the moving seat 7 to move the two positioning blocks 17 to position the accessory 3. Compared with the traditional two-cylinder setup, it reduces the equipment application cost and eliminates the need to consider the matching conditions and costs of synchronous start and stop of the two cylinders. The accessory positioning process is simple and easy to operate, which better meets the needs of accessory grinding and positioning. It also allows for adjustment of the relative distance between the two positioning blocks 17, thereby enabling the two positioning blocks 17 to be suitable for positioning accessories 3 of different shapes, making the positioning device more widely applicable.
