Description

Technical Field

[0001] This utility model relates to the field of auxiliary assembly technology, specifically a mechanical seal auxiliary assembly device. Background Technology

[0002] A mechanical seal cover is a type of mechanical seal component. During assembly, a press-fitting device is needed to press and fix the sealing gasket and the cover shell together to form a mechanical seal cover.

[0003] A search revealed that existing patent [CN 220680715 U] discloses an auxiliary assembly device for mechanical seals, including a worktable with a conveyor belt on its surface, support legs fixedly connected to the bottom of the worktable, a motor fixedly mounted on the side of the worktable, a connecting frame fixedly connected to the side of the worktable, a pressing device fixedly mounted at the center of the inner top wall of the connecting frame, and a fixing mechanism movably mounted below the connecting frame. The fixing mechanism includes a base, a connecting block fixedly connected to the top of the base, an electric push rod fixedly connected to the front of the connecting block, an arc-shaped push plate fixedly connected to the top of the electric push rod, and a collection box placed at the rear of the worktable. This device solves the problems of current assembly devices being inconvenient for fixing mechanical seals, lacking defect detection and classification functions, and requiring people to walk back and forth to record assembly data and view assembly drawings in real time. This auxiliary assembly device solves the problem of lacking fixing facilities when pressing and assembling mechanical seal covers.

[0004] While the aforementioned utility model patent solves the problem of lacking fixing facilities during the pressing and assembly of mechanical seal caps, most auxiliary assembly devices in the prior art cannot clamp and fix the cap, nor can they position the cap in the appropriate position for assembly. During use, if the cap cannot be clamped and fixed, it may shift during assembly, resulting in assembly failure and poor device performance. If the cap cannot be moved to the appropriate position, it may lead to inaccurate placement by the operator, resulting in poor assembly or even preventing normal assembly work. This makes the device less practical and inconvenient to unload the assembled seal cap. Traditional unloading methods involve manual unloading, increasing the workload of the operator and reducing the convenience of unloading, thus compromising the device's overall usability. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary assembly device for mechanical seals to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanical seal auxiliary assembly device, comprising a worktable, a clamping and positioning mechanism provided inside the worktable, the clamping and positioning mechanism including a motor bracket, a motor bracket fixedly connected to one side of the worktable, a motor fixedly connected to the inner side of the motor bracket, an output shaft of the motor fixedly connected to a motor shaft via a coupling, the outer wall of the motor shaft penetratingly connected to one side of the worktable, a ball screw fixedly connected to one end of the motor shaft, a ball nut movably connected to the outer wall of the ball screw, a connecting rod fixedly connected to the outer wall of the ball nut, a sliding groove provided on the top of the worktable, a slide rail fixedly connected inside the sliding groove, the outer wall of the slide rail slidably connected to the inner wall of the connecting rod, a support plate fixedly connected to the top of the connecting rod, a first electric push rod fixedly connected to one side of the support plate, and a clamping plate fixedly connected to one end of the first electric push rod.

[0007] As a preferred technical solution, the number of motor brackets is two, and the two motor brackets are symmetrically arranged with the vertical center line of the worktable as the axis of symmetry.

[0008] As a preferred technical solution, the number of connecting rods is two, and the two connecting rods are symmetrically arranged with the vertical center line of the ball nut as the axis of symmetry.

[0009] As a preferred technical solution, the number of clamping plates is two, and the two clamping plates are symmetrically arranged with the vertical center line of the workbench as the axis of symmetry.

[0010] As a preferred technical solution, a support frame is fixedly connected to the other side of the workbench, a third electric push rod is fixedly connected to the bottom of the support frame, and a pressure plate is fixedly connected to the bottom end of the third electric push rod.

[0011] As a preferred technical solution, a feeding mechanism is provided on one side of the support frame. The feeding mechanism includes a second electric push rod. The second electric push rod is fixedly connected to one side of the support frame, and a push plate is fixedly connected to one end of the second electric push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a clamping and positioning mechanism, can achieve the functions of clamping and fixing the cover and positioning the cover in a suitable position. During use, the cover is clamped and fixed by activating the first electric push rod, and the clamped cover is moved to the suitable position by activating the motor. This can avoid the situation where the cover cannot be clamped and fixed, which would cause the cover to deviate during pressing, thus causing the sealing cover assembly failure. This ensures the stability of the device during assembly and also avoids the situation where the cover cannot be moved to the suitable position, which may lead to inaccurate placement by manual placement, resulting in poor assembly effect or inability to perform normal assembly work. This ensures the accuracy of the device.

[0014] 2. The present invention, through the setting of the unloading mechanism, can facilitate the unloading of the assembled sealing cap. During use, by activating the second electric push rod, the push plate is moved, causing the push plate to push the assembled sealing cap off the worktable for unloading. This avoids the situation where the workload of the workers is increased and the unloading is not convenient due to the traditional manual unloading method, thus ensuring the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1 As shown, the present invention provides the following technical solution, including a workbench 1, a clamping and positioning mechanism 2 inside the workbench 1, a support frame 4 fixedly connected to the other side of the workbench 1, a third electric push rod 5 fixedly connected to the bottom of the support frame 4, a pressure plate 6 fixedly connected to the bottom end of the third electric push rod 5, and a feeding mechanism 3 provided on one side of the support frame 4.

[0022] When this device is needed to assist in the assembly of mechanical seals, the cover is first placed in the center of the workbench 1, and then the sealing gasket is placed on the cover. Before pressing the sealing gasket and the cover together, the cover needs to be clamped, fixed, and positioned directly below the pressure plate 6 for assembly. The clamping and positioning mechanism 2 is used to clamp and fix the cover and position it in the appropriate position for assembly. Then the assembly work can begin. At this time, the third electric push rod 5 is activated, causing the third electric push rod 5 to extend. The third electric push rod 5 drives the pressure plate 6 to descend, thereby causing the pressure plate 6 to press and fix the cover and the sealing gasket together, thus completing the assembly work. After the assembly is completed, the assembled sealing cover needs to be unloaded. The unloading mechanism 3 is used to unload the assembled and pressed cover, thus completing the work.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a clamping and positioning mechanism 2 is provided inside the worktable 1. The clamping and positioning mechanism 2 includes a motor bracket 201. The motor bracket 201 is fixedly connected to one side of the worktable 1. A motor 202 is fixedly connected to the inner side of the motor bracket 201. The output shaft of the motor 202 is fixedly connected to a motor shaft 203 via a coupling. The outer wall of the motor shaft 203 is connected through to one side of the worktable 1. A ball screw 204 is fixedly connected to one end of the motor shaft 203. A ball nut 205 is movably connected to the outer wall of the ball screw 204. A connecting rod 206 is fixedly connected to the outer wall of the ball nut 205. A slide groove 207 is provided on the top of the worktable 1. A connecting rod 206 is fixedly connected inside the slide groove 207. The slide rail 208 has its outer wall slidably connected to the inner wall of the connecting rod 206. A support plate 209 is fixedly connected to the top of the connecting rod 206. A first electric push rod 210 is fixedly connected to one side of the support plate 209. A clamping plate 211 is fixedly connected to one end of the first electric push rod 210. There are two motor brackets 201, which are symmetrically arranged about the vertical center line of the worktable 1. There are two connecting rods 206, which are symmetrically arranged about the vertical center line of the ball nut 205. There are two clamping plates 211, which are symmetrically arranged about the vertical center line of the worktable 1.

[0024] Specifically: When this device is needed to assist in the assembly of mechanical seals, first, the cover is placed in the center of the workbench 1, and then the sealing gasket is placed on the cover. Before pressing the sealing gasket and the cover together, the cover needs to be clamped, fixed, and positioned directly below the pressure plate 6 for assembly. At this time, the first electric push rod 210 is activated, causing it to extend. The first electric push rod 210 drives the clamping plate 211 to move, so that the two clamping plates 211 clamp and fix the cover. Then, the motor 202 is activated, causing the motor shaft 203 to rotate. 203 drives the ball screw 204 to start rotating. The ball screw 204 drives the ball nut 205 to move on the ball screw 204. The ball nut 205 drives the two connecting rods 206 to start moving, so that the two connecting rods 206 slide in the slide rail 208, thereby making the movement of the two connecting rods 206 more stable and smooth. The two connecting rods 206 drive the support plate 209 to start moving. The support plate 209 drives the clamping plate 211 to start moving. The clamping plate 211 drives the clamped and fixed cover to move, moving the cover to the position directly below the pressure plate 6, thereby completing the clamping and positioning work.

[0025] like Figure 1 and Figure 4 As shown, a feeding mechanism 3 is provided on one side of the support frame 4. The feeding mechanism 3 includes a second electric push rod 301. The second electric push rod 301 is fixedly connected to one side of the support frame 4, and a push plate 302 is fixedly connected to one end of the second electric push rod 301.

[0026] In this process: After assembly, the assembled sealing cover needs to be unloaded. At this time, the second electric push rod 301 is activated, causing the second electric push rod 301 to extend. The second electric push rod 301 drives the push plate 302 to move, so that the push plate 302 unloads the assembled sealing cover, thereby completing the unloading work.

[0027] The working principle of this utility model is as follows: When this device is needed to assist in the assembly of mechanical seals, firstly, the cover is placed in the center of the workbench 1, and then the sealing gasket is placed on the cover. Before pressing the sealing gasket and the cover together, the cover needs to be clamped, fixed, and positioned directly below the pressure plate 6 for assembly. At this time, the first electric push rod 210 is activated, causing it to extend. The first electric push rod 210 drives the clamping plate 211 to move, so that the two clamping plates 211 clamp and fix the cover. Then, the motor 202 is activated, causing the motor shaft 203 to rotate. The motor shaft 203 drives the ball screw 204 to rotate, and the ball screw 204 drives the ball nut 205 to move on the ball screw 204. The ball nut 205 drives the two connecting rods 206 to move, so that the two connecting rods 206 slide in the slide rail 208, thereby... The two connecting rods 206 move more smoothly and steadily, driving the support plate 209 to move. The support plate 209 then drives the clamping plate 211 to move, which in turn moves the clamped and fixed cover, moving it directly below the pressure plate 6 to complete the clamping and positioning. Assembly can then begin. At this point, the third electric push rod 5 is activated, extending and lowering the pressure plate 6, pressing it against the sealing gasket to secure the cover. After assembly, the sealed cover needs to be unloaded. The second electric push rod 301 is activated, extending and moving the push plate 302 to unload the assembled sealing cover.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
