Description

Technical Field

[0001] The utility model specifically relates to a filter clamping mechanism. Background Art

[0002] A filter is a device widely used in various machinery and automobiles, and its main function is to filter impurities. The finished filter has installation threaded holes. During the production process of the filter, especially before the filter is warehoused, a series of tests need to be carried out on the filter. Among them, the thread detection in the installation holes is an essential process. There are already related devices on the market that can automatically detect the threads of filters. Whether it is to transfer the filter to be detected to the detection station or to take out the detected filter and transfer it to the next station, a filter clamping mechanism is required.

[0003] For example, the Chinese utility model patent document with the publication number "CN219819391U" discloses a product transfer clamping plate for a filter leak detection device. The transfer clamping plate mainly consists of a main clamp, a sub-clamp, a clamp driving component, an elastic tensioning mechanism, and wear-resistant anti-slip blocks. A number of mutually corresponding V-shaped clamping mouths are provided on both the main clamp and the sub-clamp, forming a quadrilateral clamping position for clamping the filter. The clamp driving component can drive the relative displacement of the main clamp and the sub-clamp, and the elastic tensioning mechanism is arranged between adjacent quadrilateral clamping positions to provide an inward clamping force. In addition, wear-resistant anti-slip blocks are installed at each V-shaped clamping mouth to increase the friction with the filter and improve the clamping stability and service life.

[0004] However, the above transfer clamping mechanism still has the following defects:

[0005] Combined with the attached drawings of the specification of this publication Figure 4 It can be clearly seen that the tension spring body 4 (i.e., the elastic tensioning mechanism) is arranged between the main clamp and the sub-clamp, and the connection with the main clamp and the sub-clamp is respectively realized by the hooks at both ends of the tension spring body 4. This layout can only achieve the elastic change between the main clamp and the sub-clamp, and does not directly act on the filter in each V-shaped clamping mouth. Moreover, due to the inevitable errors in the filter, V-shaped clamping mouths, etc., the clamping force of each clamping mouth on the filter is not in the best elastic change state. If there are significant differences in the clamping force between different clamping mouths, the filter may be displaced or overturned due to the loosening of some clamping mouths during the transfer process. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a filter clamping mechanism in view of the deficiencies of the above-mentioned prior art, and solve the problem of unstable clamping force of each clamping mouth on the filter caused by errors such as filters and V-shaped clamping mouths in the prior art.

[0007] To achieve the above object, the present utility model provides the following technical solution: a filter clamping mechanism, including a main clamp, a sub-clamp, and a clamp driving component for driving the relative displacement of the main clamp and the sub-clamp. A plurality of corresponding clamping openings are provided on both the main clamp and the sub-clamp. The corresponding clamping openings between the main clamp and the sub-clamp form a clamping position for clamping the filter. It is characterized in that: a set of floating clamping blocks is provided on the main clamp or the sub-clamp corresponding to each set of clamping positions. An elastic tensioning component is linked at one end of the floating clamping block away from the clamping position, and the elastic tensioning component is linked with the main clamp or the sub-clamp.

[0008] With the above technical solution, by providing a set of floating clamping blocks on the main clamp or the sub-clamp corresponding to each set of clamping positions, and connecting the floating clamping blocks through an elastic tensioning component, each clamping position can adaptively adjust the clamping force according to actual needs, ensuring the uniformity of the clamping force and the best elastic change state, thus avoiding the risk of displacement or overturning of the filter due to loosening of some clamping openings during transportation, and also avoiding the risk of deformation of the filter due to excessive tightness of some clamping openings during transportation. In summary, this technical solution solves the problem of unstable clamping force of each clamping opening on the filter caused by errors such as the filter and V-shaped clamping openings in the prior art.

[0009] The above filter clamping mechanism can be further set as: the elastic tensioning component includes a spring. The main clamp or the sub-clamp is provided with an installation hole corresponding to each set of clamping positions. The installation hole is open at one end facing the floating clamping block and blocked at the other end. The spring is inserted into the installation hole and one end of the spring is connected to the floating clamping block.

[0010] With the above technical solution, the installation hole is set to be open at one end and closed at the other end, aiming to facilitate one end of the spring to extend out from the opening and be connected to the floating clamping block, while the other end of the spring is limited at the closed end, so that the spring can elastically expand and contract, thereby adapting to the position change of the floating clamping block to enable the floating clamping block to obtain the best elastic clamping force.

[0011] The above filter clamping mechanism can be further set as: the elastic tensioning component further includes at least one set of guide rods. One end of the guide rod is connected to the floating clamping block. The main clamp or the sub-clamp is provided with guide holes. The guide holes are distributed on one side of the installation hole and are parallel to each other. The guide rod is inserted into the guide hole. A linear bearing is sleeved on the outer periphery of the guide rod. The linear bearing is limited in the guide hole. The floating clamping block can drive the guide rod to reciprocate along the axis of the guide hole.

[0012] With the above technical solution, by connecting guide rods to the floating clamping block and inserting these guide rods into the guide holes on the main fixture or the sub-fixture, precise control of the movement direction of the floating clamping block is achieved, ensuring that the floating clamping block can reciprocate stably along the established direction, thereby making the clamping force more uniform and controllable. Further, by sleeving linear bearings on the outer periphery of the guide rods and positioning the linear bearings within the guide holes, the friction between the guide rods and the guide holes is effectively reduced, improving the smoothness and response speed of the movement of the floating clamping block.

[0013] The above-mentioned filter clamping mechanism can be further arranged as follows: both ends of the guide hole are open, the other end of the guide rod is provided with a limit retaining ring, the outer diameter of the limit retaining ring is larger than the outer diameter of the upper opening of the guide hole, a screw is provided on the end face of the limit retaining ring away from the guide rod, a through hole is provided in the middle of the limit retaining ring, a threaded hole is provided at the other end of the guide rod, and the threaded section of the screw passes through the through hole until it is connected to the threaded hole.

[0014] With the above technical solution, by setting a limit retaining ring with an outer diameter larger than the outer diameter of the upper opening of the guide hole at the other end of the guide rod, the movement range of the guide rod is effectively limited, ensuring that it reciprocates within the preset stroke, thereby avoiding improper clamping of the filter caused by excessive movement of the floating clamping block. In addition, a screw is provided on the end face of the limit retaining ring away from the guide rod, and the threaded section of the screw passes through the through hole in the middle of the limit retaining ring and is connected to the threaded hole at the other end of the guide rod, making the fixing method of the limit retaining ring simple and reliable, facilitating adjustment and maintenance. At the same time, this adjustable fixing method allows for fine-tuning of the working length of the guide rod within a certain range to adapt to the clamping requirements of filters of different sizes, improving the adaptability and flexibility of the clamping mechanism.

[0015] The above-mentioned filter clamping mechanism can be further arranged as follows: a first V-shaped clamping opening is provided on the floating clamping block, and a second V-shaped clamping opening corresponding to the first V-shaped clamping opening is provided on the main fixture or the sub-fixture, and the first V-shaped clamping opening and the second V-shaped clamping opening form a quadrilateral clamping position for clamping the filter.

[0016] With the above technical solution, the contact points between the quadrilateral clamping position formed by the two V-shaped clamping openings and the filter are all tangent, and there will still be a large-area surface contact on the abutting surface, so that filters of different specifications can be clamped with the same pair of clamping plates, without the need to frequently replace the main fixture and the sub-fixture, greatly improving the adaptability of the clamping plates.

[0017] The above-mentioned filter clamping mechanism can be further arranged as follows: wear-resistant anti-slip blocks are respectively provided on both sides of the first V-shaped clamping opening and the second V-shaped clamping opening, the wear-resistant anti-slip blocks are made of silica gel material, and the wear-resistant anti-slip blocks are fixed on the main fixture or the sub-fixture and the floating clamping block through pressing plates.

[0018] With the above technical solution, by setting wear-resistant anti-slip blocks, the clamping stability between the quadrilateral clamping position and the filter is improved, and its service life is extended. Further, the wear-resistant anti-slip blocks are fixed on the main fixture, the sub-fixture or the floating clamping block through pressing plates, making the connection between the wear-resistant anti-slip blocks and the main fixture, the sub-fixture or the floating clamping block more stable. It should be noted that: if the floating clamping block is installed on the main fixture, the wear-resistant anti-slip blocks are fixed on the sub-fixture and the floating clamping block through pressing plates; if the floating clamping block is installed on the sub-fixture, the wear-resistant anti-slip blocks are fixed on the main fixture and the floating clamping block through pressing plates; both of the above situations are optional.

[0019] The above-mentioned filter clamping mechanism can be further set as follows: the fixture driving assembly includes opening clamp cylinders arranged on both sides of the main fixture and the sub-fixture; the output ends of the opening clamp cylinders are respectively connected to the main fixture and the sub-fixture, and drive the main fixture and the sub-fixture to move towards or in opposite directions.

[0020] With the above technical solution, the opening clamp cylinder is a cylinder with bidirectional output at both ends. After the cylinder is connected to the main fixture and the sub-fixture, it can drive the main fixture and the sub-fixture to open or close, thereby completing clamping and loosening.

[0021] The above-mentioned filter clamping mechanism can be further set as follows: a set of pulling cylinders are respectively arranged in the middle of the main fixture and the sub-fixture. There is a connecting bolt between the two sets of pulling cylinders. The two ends of the connecting bolt are respectively threadedly connected to the output ends of a set of pulling cylinders. The bodies of the pulling cylinders are respectively connected with support plates by screws, and the support plates are connected to the main fixture or the sub-fixture by screws.

[0022] With the above technical solution, the output ends (i.e., the piston rods of the cylinders) of the two sets of pulling cylinders are relatively fixed through the connecting bolt. The output end (i.e., the piston rod of the cylinder) of each set of cylinders moves relative to its own cylinder body, so as to realize the approach and separation of the two sets of pulling cylinders. The two pulling cylinders pull against each other, playing a role in assisting the main fixture and the sub-fixture on both sides, and improving the clamping stability.

[0023] The above-mentioned filter clamping mechanism can be further set as follows: a wire pressing buckle is arranged on the main fixture or the sub-fixture. One end of the wire pressing buckle is connected to the main fixture or the sub-fixture by screws, and an arc-shaped wire groove is arranged in the middle of the wire pressing buckle.

[0024] With the above technical solution, by setting the wire pressing buckle and arranging an arc-shaped wire groove in the middle, wire harnesses, air pipes, etc. can be clamped. One end of the wire pressing buckle is fixed with screws, and the other end uses its own structural form to stably clamp wire harnesses, air pipes, etc., and at the same time it is convenient to disassemble and remove wire harnesses, air pipes, etc.

Detailed Description of the Preferred Embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figures 1 to 6 shown, the filter clamping mechanism includes a main fixture 1, a sub-fixture 2, and a fixture driving component for driving the relative displacement of the main fixture 1 and the sub-fixture 2. A plurality of corresponding clamping openings are provided on both the main fixture 1 and the sub-fixture 2, and the corresponding clamping openings between the main fixture 1 and the sub-fixture 2 form a clamping position for clamping the filter.

[0035] A set of floating clamping blocks 3 is provided at each set of clamping openings of the main fixture 1. An elastic tensioning component is linked at one end of the floating clamping block 3 away from the clamping position, and the elastic tensioning component is linked with the main fixture 1.

[0036] The elastic tensioning assembly includes a spring 4. A set of mounting holes 5 are provided at each clamping opening of the main fixture 1. The mounting holes 5 are open at one end facing the floating clamping block 3 and closed at the other end. The spring 4 is inserted into the mounting hole 5 and one end of the spring 4 is connected to the floating clamping block 3. The mounting hole 5 is set to be open at one end and closed at the other end for the purpose of facilitating one end of the spring 4 to extend out from the opening and connect to the floating clamping block 3, while the other end of the spring 4 is limited at the closed end. In this way, the spring 4 can undergo elastic expansion and contraction to adapt to the position change of the floating clamping block 3, so that the floating clamping block 3 can obtain the optimal elastic clamping force.

[0037] The elastic tensioning assembly further includes two sets of guide rods 6. One end of each set of guide rods 6 is connected to the floating clamping block 3. Guide holes 7 are provided on the main fixture 1. The guide holes 7 are distributed on one side of the mounting holes 5 and are parallel to each other. The guide rods 6 are inserted into the guide holes 7. A linear bearing 8 is sleeved on the outer periphery of the guide rod 6. The linear bearing 8 is limited within the guide hole 7. The floating clamping block 3 can drive the guide rod 6 to reciprocate along the axis of the guide hole 7. By connecting the guide rods 6 to the floating clamping block 3 and inserting these guide rods 6 into the guide holes 7 on the main fixture 1, the precise control of the movement direction of the floating clamping block 3 is achieved, ensuring that the floating clamping block 3 can stably reciprocate along the established direction, thereby making the clamping force more uniform and controllable. Further, by sleeving the linear bearing 8 on the outer periphery of the guide rod 6 and limiting the linear bearing 8 within the guide hole 7, the friction between the guide rod 6 and the guide hole 7 is effectively reduced, improving the smoothness and response speed of the movement of the floating clamping block 3.

[0038] Both ends of the guide hole 7 are open. A limit retaining ring 9 is provided at the other end of the guide rod 6. The outer diameter of the limit retaining ring 9 is larger than the outer diameter of the upper opening of the guide hole 7. By providing the limit retaining ring 9 with an outer diameter larger than the outer diameter of the upper opening of the guide hole 7 at the other end of the guide rod 6, the movement range of the guide rod 6 is effectively limited, ensuring that it reciprocates within the preset stroke, thereby avoiding improper clamping of the filter due to excessive movement of the floating clamping block 3. A screw is provided on the end face of the limit retaining ring 9 away from the guide rod 6. A through hole is provided in the middle of the limit retaining ring 9. A threaded hole is provided at the other end of the guide rod 6. The threaded section of the screw passes through the through hole until it is connected to the threaded hole. By connecting the threaded section of the screw through the through hole in the middle of the limit retaining ring 9 to the threaded hole at the other end of the guide rod 6, the fixing method of the limit retaining ring 9 is simple and reliable, facilitating adjustment and maintenance. At the same time, this adjustable fixing method allows fine-tuning of the working length of the guide rod 6 within a certain range to adapt to the clamping requirements of filters of different sizes, improving the adaptability and flexibility of the clamping mechanism.

[0039] The floating clamping block 3 is provided with a first V-shaped clamping opening 10, and the sub-fixture 2 is provided with a second V-shaped clamping opening 11 corresponding to the first V-shaped clamping opening 10. The first V-shaped clamping opening 10 and the second V-shaped clamping opening 11 form a quadrilateral clamping position for clamping the filter. The contact points between the quadrilateral clamping position formed by the two V-shaped clamping openings and the filter are all tangent, and there will still be a large-area surface contact at their abutting surfaces. Thus, different specifications of filters can be clamped by the same pair of clamping plates, without the need to frequently replace the main fixture 1 and the sub-fixture 2, greatly improving the adaptability of the clamping plates.

[0040] Both sides of the first V-shaped clamping opening 10 and the second V-shaped clamping opening 11 are respectively provided with wear-resistant anti-slip blocks 12. The wear-resistant anti-slip blocks 12 are made of silica gel, and the wear-resistant anti-slip blocks 12 are fixed on the sub-fixture 2 and the floating clamping block 3 through pressing plates 13. By setting the wear-resistant anti-slip blocks 12, the clamping stability between the quadrilateral clamping position and the filter is improved, and its service life is extended. Further, the wear-resistant anti-slip blocks 12 are fixed on the sub-fixture 2 and the floating clamping block 3 through pressing plates 13, making the connection between the wear-resistant anti-slip blocks 12 and the sub-fixture 2 and the floating clamping block 3 more stable.

[0041] The fixture driving component includes opening clamp cylinders 14 arranged on both sides of the main fixture 1 and the sub-fixture 2; the output ends of the opening clamp cylinders 14 are respectively connected to the main fixture 1 and the sub-fixture 2, and drive the main fixture 1 and the sub-fixture 2 to move towards or in opposite directions. The opening clamp cylinders 14 are cylinders with double-end bidirectional output. After the cylinders are connected to the main fixture 1 and the sub-fixture 2, they can drive the main fixture 1 and the sub-fixture 2 to open or close, thus completing clamping and loosening.

[0042] A set of tension cylinders 15 are respectively arranged in the middle of the main fixture 1 and the sub-fixture 2. A connecting bolt 16 is arranged between the two sets of tension cylinders 15. The two ends of the connecting bolt 16 are respectively threadedly connected to the output ends of a set of tension cylinders 15. The bodies of the tension cylinders 15 are respectively connected with support plates 17 through screws, and the support plates 17 are connected to the main fixture 1 or the sub-fixture 2 through screws. The output ends (i.e., the piston rods of the cylinders) of the two sets of tension cylinders 15 are relatively fixed between the connecting bolts 16, and the output end (i.e., the piston rod of the cylinder) of each set of tension cylinders 15 moves relative to its own cylinder body, so as to realize the approach and separation of the two sets of tension cylinders 15. The two tension cylinders 15 pull against each other, playing a role in assisting the main fixture 1 and the sub-fixture 2 on both sides and improving the clamping stability.

[0043] Both the main fixture 1 and the auxiliary fixture 2 are provided with wire pressing buckles 18. One end of the wire pressing buckle 18 is connected to the main fixture 1 or the auxiliary fixture 2 by screws, and an arc-shaped wire groove 19 is provided in the middle of the wire pressing buckle 18. By setting the wire pressing buckle 18 and the arc-shaped wire groove 19 in the middle, it is possible to clamp wire harnesses, air pipes, etc. One end of the wire pressing buckle 18 is fixed with screws, and the other end uses its own structural form to stably clamp wire harnesses, air pipes, etc., while facilitating the removal of wire harnesses, air pipes, etc.

[0044] Working principle: The opening clamp cylinders 14 on both sides and the two groups of pulling cylinders 15 in the middle drive the main fixture 1 and the auxiliary fixture 2 to approach each other at the same time. During the process of clamping the filter, the floating clamping block 3 will adaptively adjust the clamping force between it and the filter under the action of the spring 4 and the guide rod 6 to obtain the best clamping force.

[0045] In this embodiment, a set of floating clamping blocks 3 are arranged on the main fixture 1 corresponding to each clamping position, and the floating clamping blocks 3 are connected by an elastic tensioning assembly, so that each clamping position can adaptively adjust the clamping force according to actual needs, ensuring the uniformity of the clamping force and the best elastic change state. Therefore, the risk of displacement or tipping of the filter due to loosening of some clamping mouths during transportation is avoided, and at the same time, the risk of deformation of the filter due to excessive tightness of some clamping mouths during transportation is also avoided.
