Description

Technical Field

[0001] The utility model relates to the technical field of automated conveying, in particular to a non-rebound device for buffering an electric stopper of a conveying line. Background Art

[0002] The existing electric stopper of the conveyor line has no cylinder push for the buffer reset function because the power source replaces the air source. The buffer block can only be reset by the reset elastic force of the hydraulic buffer. When the workpiece is lifted and separated from the stopper, the buffer block will automatically rebound without the locking function. The workpiece will fall and just press on the buffer block, and the stop function will fail. Summary of the invention

In order to achieve the above-mentioned purpose and other advantages according to the present invention, a non-rebound device for electric stoppers of conveyor lines to buffer in place is provided, comprising:

[0004] A bottom component, a top component sleeved on the bottom component, and a buffer component disposed in the bottom component, wherein the buffer component and the top component are fixedly connected;

[0005] The buffer assembly includes a buffer fixing block, a hydraulic buffer movably connected to the buffer fixing block, and a self-locking block rotatably connected to the bottom of the buffer fixing block;

[0010] Preferably, a pin hole is provided on the top seat, a pin is inserted into the pin hole, a buffer block is sleeved on the pin, and the buffer block swings around the pin, wherein the pin and the top seat have an interference fit, and the pin and the buffer block have a clearance fit.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-7 , a non-rebound device for buffering electric stoppers on conveyor lines, comprising:

[0022] The bottom component 2, the top component 1 sleeved on the bottom component 2 and the buffer component 3 arranged in the bottom component 2, wherein the buffer component 3 and the top component 1 are fixedly connected; the top component 1 can move up and down under the action of the power supply. The internal mechanism of the top component 1 and the bottom component 2 belongs to the category of electric stoppers and will not be described here.

[0023] As shown in 2, 6-7, the buffer assembly 3 includes a buffer fixed block 31, a hydraulic buffer 32 movably connected to the buffer fixed block 31, and a self-locking block 35 rotatably connected to the bottom of the buffer fixed block 31; the buffer fixed block 31 is provided with a plurality of guide holes, a guide rod 34 is inserted into each guide hole, and a card slot 341 is provided on the guide rod 34, a buffer flange 37 is fixedly connected to the guide rod 34, the buffer flange 37 and the hydraulic buffer 32 are interference fit, and the end of the hydraulic buffer 32 away from the buffer flange 37 is fixed to the buffer fixed block 31; the self-locking block 35 limits the guide rod 34 to prevent the buffer assembly 3 from rebounding after the external pressure is removed. The self-locking block 35 has an L-shaped structure as a whole, and includes a straight section card segment, a straight rod segment 351 which is integrally connected to the straight section card segment and has an L-shaped structure with the straight section card segment, and a spring ejector pin 36 vertically fixed to the straight rod segment. The straight section card segment contacts a guide rod 34, the spring ejector pin 36 contacts another guide rod 34, and the end of the straight section card segment matches the card slot 341. When the hydraulic buffer 32 is compressed and descends, driving the guide rod 34 to descend, the card slot on the guide rod 34 is just locked by one side of the self-locking block 35, so that the hydraulic buffer 32 will not rebound after the external pressure is removed. When the hydraulic buffer 32 is subjected to the impact force of the top component 1, the hydraulic buffer 32 starts the buffering effect on the top component 1. When the hydraulic buffer 32 moves toward the bottom component 2 under the force of the top component 1, the hydraulic buffer 32 moves toward the bottom component 2 together with the guide rod 34. At this time, a slot 341 of the guide rod 34 is exposed, and the straight segment of the self-locking block 35 is located in the slot 341. The spring ejector pin 36 of the self-locking block 35 is tightly attached to the other guide rod 34. When the upward impact force of the top component 1 disappears, the guide rod 34 is clamped by the self-locking block 35, and the hydraulic buffer 32 will not rebound. When the stopper needs to be released, force is applied to the top component 1 so that the hydraulic buffer 32 continues to move toward the bottom component 2. The straight rod section 351 of the self-locking block 35 touches the conical ejector pin 23. The straight rod section 351 of the self-locking block 35 rotates under the action of the conical ejector pin 23. The straight segment of the self-locking block 35 rotates out of the slot 341 of the guide rod 34. The guide rod 34 is not locked. The force applied by the top component 1 is canceled, and the top component 1 and the buffer component 3 move away from the bottom component 2 for reset. The buffer block 12 resets during the lifting process of the hydraulic buffer 32, and then the top component 1 rises to prepare for the next buffering.

[0024] Further, such as Figure 3-4The top component 1 includes a top seat 11 with a hollow interior, a buffer block 12 movably connected to the top seat 11, and an avoidance hole 112 opened on the top surface of the top seat 11, so that the buffer component 3 will not be interfered when moving up and down. The buffer component 3 is fixedly connected to the avoidance hole 112. A through pin hole is opened on the top seat 11, and a pin shaft 13 is inserted into the pin hole. The buffer block 12 is sleeved on the pin shaft 13, and the buffer block 12 swings around the pin shaft 13, wherein the pin shaft 13 and the top seat 11 have an interference fit, and the pin shaft 13 and the buffer block 12 have a clearance fit. The buffer block 12 is L-shaped, one side receives the impact of the workpiece, and the other side is used to compress the hydraulic buffer 32, so that the impact force is buffered.

[0025] Further, such as Figure 5 The bottom component 2 includes a base 21, in which a second avoidance hole 211 is provided, a bottom sealing plate 22 is fixedly connected to the bottom of the second avoidance hole 211, a conical top pin 23 is fixedly connected to the bottom sealing plate 22, and the buffer component 3 is located in the second avoidance hole 211.

[0026] Specifically, when the top assembly 1 is in the upper position, the hydraulic buffer 32 in the buffer assembly 3 is compressed due to the impact force and self-locks, achieving buffering in place without rebound. When the stopper needs to be released, the top assembly 1 descends, and the buffer assembly 3 descends accordingly. The straight rod section 351 of the self-locking block 35 will hit the conical ejector pin 23 on the bottom assembly 2, and the self-locking block 35 will open on one side of the slot, releasing and resetting the hydraulic buffer 32. The buffer block 12 is reset during the process of the hydraulic buffer 32 being lifted up, and then the top assembly 1 rises to prepare for the next buffering.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described here.
