Summary of the invention

[0005] The present invention is to solve the problem that after the latch enters a positioning hole, the latch may be forced to leave the positioning hole, which then affects the use effect of the latch, and proposes a latch positioning device suitable for a worm reducer.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a latch positioning device suitable for a worm reducer, comprising a fixed seat, a first bolt is threadedly inserted on one side of the fixed seat, a worm reducer is threadedly connected to one side of the first bolt, a dividing plate is provided at the input shaft of the worm reducer, a plurality of positioning holes are opened on one side of the dividing plate, a latch is inserted on one side of the fixed seat, a handwheel is provided at the input shaft of the worm reducer, a limiting assembly is provided on one side of the fixed seat, the limiting assembly comprises a placement plate, the placement plate is fixedly connected to the fixed seat, and a spring is fixedly connected to one side of the placement plate One side of the spring is fixedly connected to a connecting plate, one side of the connecting plate is fixedly connected to a latch, one side of the placement plate is fixedly connected to a slide rail, one side of the slide rail is slidably connected to a sliding block, one side of the sliding block is fixedly connected to a card block, one side of the latch is fixedly connected to the placement block, a card slot is provided on one side of the block, the size of the card slot on one side of the block is matched with the size of the card block, a telescopic rod is sleeved inside the spring, and both ends of the telescopic rod are fixedly connected to the placement plate and the connecting plate respectively, and a plurality of anti-sliding blocks are fixedly connected to both sides of the sliding block, and the anti-sliding blocks are equidistantly arranged on both sides of the sliding block.

[0007] The effect achieved by the above components is: when the latch positioning device is used on the worm reducer, the fixed seat is fixed to the flange at the input end of the worm reducer through the first bolt connection, and the dividing plate and the handwheel are fixed to the input shaft of the worm reducer through a key connection. When in use, the insertion amount of the latch is visually checked through the surface color difference between the latch and the dividing plate, thereby ultimately ensuring the positioning and stopping effect. When working, according to the positioning requirements, turn the handwheel, flip the tooling to the specified position, insert the latch assembly into the positioning hole of the dividing plate, position the mechanical structure, and pull out the latch after completion. There is a retaining ring on the latch to limit it, ensuring that the latch will not be separated from the fixed seat when the latch is pulled out after positioning is completed. When the latch is not in use, the latch is connected to the plate to stretch the spring on the placement plate and lengthen the telescopic rod. When one side of the latch needs to enter the positioning hole on one side of the indexing plate, the latch is released and the spring is reset to drive one side of the latch into the positioning hole on one side of the indexing plate. The sliding block with the anti-sliding block is moved to move the sliding block inside the slide rail. The sliding block then drives the card block to approach the latch and the card block drives the inside of the card slot on one side of the square block at the upper end of the latch to limit the position of the latch. By using a limit assembly, the position of the latch can be blocked and restricted when the latch fixes the indexing plate, so that the latch cannot move upward, thereby preventing the latch from being separated from the positioning hole on one side of the indexing plate, thereby improving the use effect of the latch positioning device.

[0008] Preferably, a stabilizing block is fixedly connected inside the slide rail, grooves are provided on both sides of the sliding block, and the stabilizing block is slidably connected to the grooves on both sides of the sliding block.

[0009] The effect achieved by the above components is: by using the stabilizing block sliding inside the groove on one side of the sliding block, the connection strength between the sliding block and the sliding rail is improved, thereby preventing the sliding rail from separating from the sliding block.

[0011] The effect achieved by the above components is: by using a magnet to absorb the iron block on one side of the slide rail, after the sliding block reaches the side of the slide rail close to the latch, it is not easy to move under force, thereby improving the use effect of the sliding block and then improving the use effect of the card block.

[0012] Preferably, one side of the latch is fixedly connected to a control frame, one side of the control frame is provided with a through hole, and a rubber sleeve is fixedly connected inside the through hole on one side of the control frame.

[0013] The effect achieved by the above components is that when the bolt is moved, the contact area between the operator and the bolt can be increased through the control frame with a rubber sleeve on one side of the bolt, making it easier for the operator to move the bolt.

[0014] Preferably, a trapezoidal block is fixedly connected to one side of the clamping block away from the clamping block, and a size of the trapezoidal block on the one side away from the clamping block is smaller than a size of the other side.

[0015] The effect achieved by the above components is: by using the trapezoidal block on one side of the card block, the size of one side of the card block is reduced, so that the card block can be more easily inserted into the card slot on one side of the block, thereby improving the use effect of the card block.

[0016] Preferably, an auxiliary component is provided on one side of the fixing seat, and the auxiliary component includes a mounting plate, one side of the mounting plate is fixedly connected to the fixing seat, one side of the mounting block is threadedly inserted with a second bolt, one side of the second bolt is threadedly connected to a positioning block, one side of the dividing plate is fixedly connected with a circular ring, one side of the circular ring is fixedly connected with a plurality of scales, one side of the second bolt is abutted with a gasket, and one side of the gasket is abutted with the mounting plate.

[0017] The effect achieved by the above components is: when using the dividing plate, the positioning block can be moved to place the positioning block on the mounting plate, and then the second bolt is rotated to pass through the mounting plate and fixed to the positioning block, and then one side of the positioning block will contact the scale on the disc, and then after the dividing plate is rotated, the positioning block will coincide with the scale, so that the operator can quickly determine the angle of rotation of the dividing plate. By using auxiliary components, the operator can easily determine the angle after the dividing plate is rotated, thereby improving the use effect of the pin positioning device.

[0018] Preferably, an inclined plate is fixedly connected to one side of the mounting plate, and the inclined plate is obliquely arranged on one side of the mounting plate.

[0019] The effect achieved by the above components is: by using the inclined plate, the inlet size of the mounting plate is increased, so that the positioning block can contact with the mounting plate more easily.

[0020] Preferably, a baffle is fixedly connected to one side of the mounting plate, and the size of the baffle is matched with the size of the positioning block.

[0021] The effect achieved by the above components is: by using the baffle plate, the position of the positioning block in contact with the mounting plate is blocked, and then it is convenient to fix the positioning block with the second bolt later.

[0022] In summary, the beneficial effects of the present invention are: When using the latch positioning device on the worm reducer, the fixed seat is fixed to the flange at the input end of the worm reducer through the first bolt connection, and the dividing plate and the handwheel are fixed to the input shaft of the worm reducer through a key connection. When in use, the insertion amount of the latch is visually checked through the surface color difference between the latch and the dividing plate, so as to ultimately ensure the positioning and stopping effect.

There is a retaining ring on the latch to limit it, ensuring that the latch will not be separated from the fixed seat when the positioning is completed. When the latch is not in use, the latch is connected to the plate to stretch the spring on the placement plate, and the telescopic rod becomes longer. When one side of the latch needs to enter the positioning hole on one side of the indexing plate, the latch is released, and the spring is reset to drive one side of the latch into the positioning hole on one side of the indexing plate. Then the sliding block with the anti-sliding block is moved to move the sliding block inside the slide rail, and then the sliding block drives the card block to approach the latch, and then the card block drives the inside of the card slot on one side of the upper block of the latch to limit the position of the latch.

[0023] By using a limit assembly, the position of the latch can be blocked and restricted when the latch fixes the dividing plate, so that the latch cannot move upward, thereby preventing the latch from escaping from the positioning hole on one side of the dividing plate, thereby improving the use effect of the latch positioning device.

[0033] Working principle: When the latch 6 positioning device is used on the worm reducer 3, the fixed seat 1 is connected and fixed to the flange at the input end of the worm reducer 3 by the first bolt 2, and the dividing plate 4 is fixed to the input shaft of the worm reducer 3 together with the hand wheel 9 by a key connection. When in use, the insertion amount of the latch 6 is visually checked through the surface color difference between the latch 6 and the dividing plate 4, so as to ultimately ensure the positioning and stopping effect. When working, according to the positioning requirements, turn the hand wheel 9, flip the tooling to the specified position, insert the latch 6 assembly into the positioning hole 5 of the dividing plate 4, and position the mechanical structure. After completion, pull out the latch 6. There is a retaining ring on the latch 6 to limit it, to ensure that pulling out the latch 6 after positioning is completed will not cause the latch 6 to separate from the fixed seat 1. When the latch 6 is not in use, the latch 6 stretches the spring 72 on the placement plate 71 through the connecting plate 73, and the telescopic rod 79 becomes longer. Then, when one side of the latch 6 needs to enter the positioning hole 5 on one side of the indexing plate 4, the latch 6 is released, and the spring 72 is reset to drive one side of the latch 6 to enter the positioning hole 5 on one side of the indexing plate 4. Then, the sliding block 75 with the anti-sliding block 714 is moved to move the sliding block 75 inside the slide rail 74. At this time, the stabilizing block 710 sliding in the groove 711 on one side of the sliding block 75 , to improve the connection strength between the sliding block 75 and the sliding rail 74, and then the sliding block 75 will drive the clamping block 76 to approach the latch 6, and then the clamping block 76 will drive the inside of the clamping groove 78 on the side of the upper block 77 of the latch 6 to limit the position of the latch 6. By using the limiting assembly 7, the position of the latch 6 can be blocked and restricted when the latch 6 fixes the indexing plate 4, so that the latch 6 cannot move upward, and the latch 6 can be prevented from escaping from the positioning hole 5 on one side of the indexing plate 4, thereby improving the use effect of the positioning device of the latch 6.

[0034] When using the dividing plate 4, the positioning block 83 can be moved so that the positioning block 83 is placed on the mounting plate 81 with the inclined plate 87. At this time, the baffle 88 is used to block the position of the positioning block 83 in contact with the mounting plate 81, and then the second bolt 82 is rotated to make the second bolt 82 pass through the mounting plate 81 and fix to the positioning block 83, and then one side of the positioning block 83 will contact the scale 85 on the disc, and then after the dividing plate 4 is rotated, the positioning block 83 will coincide with the scale 85, so that the operator can quickly determine the rotation angle of the dividing plate 4. By using the auxiliary component 8, the operator can easily determine the angle after the dividing plate 4 is rotated, thereby improving the use effect of the positioning device of the latch 6.
