Description

A multi-position adaptive wire clamp and its application method Technical Field

[0001] This invention relates to the field of wire straightening fixture technology, and more specifically, to a multi-clamping wire adaptive fixture and its method of use. Background Technology

[0002] Currently, steel enterprises produce a wide variety of wire rod specifications, and even within the same type, dimensions vary. Existing straightening machines' clamping devices cannot clamp wire rods of different specifications and dimensions, leading to situations where clamping is not secure enough during the straightening process, preventing the workpiece from being straightened and impacting production efficiency. However, manually screening wire rods based on their dimensions also affects production efficiency. Therefore, it is necessary to propose a new type of fixture to solve these problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a multi-position adaptive wire clamp and its usage method, which is applicable to situations where different specifications of wires are clamped simultaneously, ensuring that all wires are firmly clamped, improving the quality of wire straightening and increasing work efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A multi-position wire adaptive clamp includes a base, a hydraulic drive device, a sliding seat, and multiple clamping components. The surface of the base is provided with a transverse groove. The sliding seat is slidably connected to the base through the groove. The hydraulic drive device is disposed on the base and located at one end of the sliding seat. The hydraulic drive device is connected to one end of the sliding seat to drive the sliding seat to move along the groove.

[0006] Multiple clamping components are arranged side by side on the edge of the top surface of the base and located on one side of the sliding seat along its length. Each clamping component includes a first fixing member, a first movable member, a clamping stop, and a first spring. The first fixing member is disposed on the base. The clamping stop is fixedly connected to the side of the sliding seat. The first movable member is located between the first fixing member and the clamping stop. The first movable member is connected to the first fixing member through the first spring. A first clamping station that can automatically adapt to different specifications and sizes is formed between the first movable member and the clamping stop.

[0007] In one embodiment, within the same clamping assembly, a plurality of guide posts are provided on the side of the first movable member facing the first fixed member. The first fixed member is provided with guide through holes, and the guide posts pass through the guide through holes to realize the guide connection between the first movable member and the first fixed member. A limiting part is provided at one end of the guide post passing through the guide through hole to prevent the guide post from coming out of the first fixed member.

[0008] In one embodiment, the slide groove has an inverted T-shaped cross section, and the bottom of the sliding seat is provided with a connecting part that is adapted to the slide groove. The connecting part is embedded in the slide groove to prevent the sliding seat from falling off the base.

[0009] In one embodiment, the multi-position wire adaptive clamp further includes a detection component disposed on the base and located on the other side of the slide seat. The detection component and one of the clamping components are symmetrically distributed on both sides of the slide seat.

[0010] The detection assembly includes a second fixed member, a second movable member, a second spring, and a detection baffle. The second fixed member is disposed on the base, and the detection baffle is fixedly connected to the side of the sliding seat. The second movable member is located between the second fixed member and the detection baffle, and the second movable member and the second fixed member are connected by the second spring. A detection space is formed between the detection baffle and the second movable member. A connecting block is disposed on the side of the detection baffle facing the second movable member, and a pressure sensor is disposed on the side of the connecting block facing the second movable member.

[0011] The side of the second fixing member facing the detection baffle is flush with the side of the first movable member of the symmetrical clamping assembly facing the clamping block, and they are in the same plane. The side of the detection baffle facing the second movable member is flush with the side of the clamping block facing the first movable member, and they are in the same plane.

[0012] In one embodiment, the distance between the side of the connecting block facing the second movable member and the side of the detection baffle facing the connecting block is equal to the diameter of the smallest wire in the same clamping operation.

[0013] In one embodiment, the detection assembly further includes an auxiliary hydraulic cylinder disposed on the side of the detection baffle away from the second movable member. The piston rod of the auxiliary hydraulic cylinder passes through the detection baffle and is fixedly connected to the connecting block, that is, the connecting block is driven to move by the auxiliary hydraulic cylinder.

[0014] A method for using a multi-position self-adaptive wire clamp, the steps of which are as follows:

[0015] For multiple wires of the same or different specifications, before clamping the wires, the hydraulic drive device drives the sliding seat to move, so that the distance between the first moving part in the same clamping assembly and the clamping stop reaches the maximum, thus forming the first clamping station of the wire to be clamped.

[0016] After multiple wires have fully entered the first clamping station of multiple clamping components, the hydraulic drive device drives the sliding seat to move in the opposite direction, and the clamping block in the same clamping component moves towards the first movable part. During this process, the position of the first movable part is adjusted by the first spring. Under the action of the first spring, the clamping block and the first movable part clamp and fix the wires.

[0017] In one embodiment, when a detection component is configured:

[0018] When clamping and fixing the wire, the connecting block moves towards the second movable part and compresses the second spring. During this process, the pressure sensor of the connecting block detects the pressure data. When the pressure data reaches the value required for clamping and fixing, it indicates that the multi-position wire adaptive clamp is firmly clamping multiple wires. The hydraulic drive device stops driving the sliding seat to move and keeps the wire clamped.

[0019] In one embodiment, the detection component is equipped with an auxiliary hydraulic cylinder:

[0020] Before multiple wires enter the first clamping station of the multi-clamping wire adaptive fixture, the wire size is detected online to determine the minimum size value of the wire.

[0021] Based on the minimum size value, the auxiliary hydraulic cylinder drives the connecting block to move so that the distance between the side of the connecting block facing the second movable part and the side of the detection baffle facing the connecting block is equal to the minimum size value.

[0022] Subsequently, the hydraulic drive unit drives the sliding seat to move, clamping multiple wires simultaneously. At the same time, the connecting block applies pressure to the second moving part. When the pressure sensor detects that the pressure has reached the value required for clamping and fixing, it indicates that the multi-position wire adaptive clamp has firmly clamped multiple wires. The hydraulic drive unit then stops driving the sliding seat to move, maintaining the clamped wires.

[0023] In summary, the present invention has the following beneficial effects:

[0024] This invention, through the cooperation of a sliding base and multiple clamping components, is suitable for simultaneously clamping wires of different specifications, ensuring that all wires are firmly clamped, improving the quality of wire straightening and increasing work efficiency.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0033] As shown in Figures 1-4, a multi-position wire adaptive clamp includes a base 1, a hydraulic drive device 3, a sliding seat 2, and multiple clamping components 4. As shown in the perspective of Figure 1, the surface of the base 1 is provided with a transverse sliding groove. The sliding seat 2 is slidably connected to the base 1 through the sliding groove. The hydraulic drive device 3 is disposed on the base 1 and located at the left end of the sliding seat 2. The hydraulic drive device 3 is connected to the left end of the sliding seat 2 to drive the sliding seat 2 to move along the sliding groove.

[0034] Multiple clamping components 4 are arranged side by side on the edge of the top surface of the base 1 and located on one side of the sliding seat 2 along its length. Each clamping component 4 includes a first fixing member 41, a first movable member 42, a clamping block 43, and a first spring 44. The first spring 44 is a high-strength extension spring 44. The first fixing member 41 is disposed on the base 1. The clamping block 43 is fixedly connected to the side of the sliding seat 2 and moves with the sliding seat 2. The first movable member 42 is located between the first fixing member 41 and the clamping block 43, and the first movable member 42 is connected to the first fixing member 41 through the first spring 44. A first clamping station that can automatically adapt to different specifications and sizes is formed between the first movable member 42 and the clamping block 43.

[0035] In this invention, the hydraulic drive device 3 is preferably a hydraulic cylinder, which can provide a stable clamping force.

[0036] As shown in Figures 1-3, in a specific embodiment, the present invention selects five clamping components 4 to form five clamping stations on the base 1 and on one side of the sliding seat 2. The method of using the present invention is as follows:

[0037] For multiple wires of the same or different specifications, before clamping the wires, the hydraulic drive device 3 drives the sliding seat 2 to move, so that the distance between the first movable part 42 and the clamping stop 43 in the same clamping assembly 4 reaches the maximum, and at this time the first clamping station of the wire to be clamped is formed.

[0038] After multiple wires have fully entered the first clamping position of multiple clamping components 4, the hydraulic drive device 3 drives the sliding seat 2 to move in the opposite direction, and the clamping block 43 in the same clamping component 4 moves towards the first movable member 42. During this process, the position of the first movable member 42 is adjusted by the first spring 44. Under the action of the first spring 44, the clamping block 43 and the first movable member 42 clamp and fix the wires.

[0039] As shown in Figure 1-2, for two adjacent clamping components 4, the clamping block 43 of one clamping component 4 is adjacent to the first fixing member 41 of the other adjacent clamping component 4. That is, a second clamping station suitable for clamping wires of the same specification can also be formed between the clamping block 43 of one clamping component 4 and the first fixing member 41 of the other adjacent clamping component 4.

[0040] Therefore, the method of use of the present invention also includes the case of wires of the same specification only. For multiple wires of the same specification, the wires can be clamped and fixed through the second clamping station, as follows:

[0041] Before clamping the wire, the hydraulic drive device 3 drives the sliding seat 2 to move, so that the clamping block 43 in the same clamping assembly 4 approaches the first movable member 42. At this time, the clamping block 43 of one clamping assembly 4 and the adjacent first fixed member 41 of another clamping assembly 4 form a second clamping station for the wire to be clamped.

[0042] After multiple wires have fully entered the multiple second clamping stations, the hydraulic drive device 3 drives the sliding seat 2 to move in the opposite direction, and the clamping block 43 moves towards the adjacent first fixing member 41, thereby clamping and fixing the wires.

[0043] It is easy to understand that for wires of the same specification, this invention can achieve clamping and fixing through either the first clamping station, which allows for more adjustment space, or through the second clamping station, which is equivalent to the existing clamping method. However, for wires of different specifications, clamping and fixing can only be achieved through the first clamping station. The first spring 44 inside the clamping assembly 4 can be adapted to wires of different specifications. In a single clamping operation, multiple wires of different specifications can be firmly clamped on the adaptive clamp of this invention.

[0044] Furthermore, within the same clamping assembly 4, multiple sets of guide posts 45 are provided on the side of the first movable member 42 facing the first fixed member 41. The first fixed member 41 is provided with guide through holes, and the guide posts 45 pass through the guide through holes to realize the guide connection between the first movable member 42 and the first fixed member 41. A limiting part is provided at one end of the guide post 45 passing through the guide through hole to prevent the guide post 45 from coming out of the first fixed member 41. That is, in the unclamped state, the first spring 44 is in a compressed state.

[0045] It is easy to understand that the first fixing member 41 has a receiving groove on the side away from the first moving member 42 to receive the limiting part at the end of the guide post 45. In the unclamped state, the limiting part at the end of the guide post 45 is in the receiving groove and will not protrude from the surface of the first fixing member 41.

[0046] Furthermore, as shown in Figure 3, the cross-section of the slide groove is inverted T-shaped, and the bottom of the sliding seat 2 is provided with a connecting part 21 that is adapted to the slide groove. The connecting part 21 is embedded in the slide groove to prevent the sliding seat 2 from falling out of the base 1.

[0047] Furthermore, in order to detect the clamping force in real time, the present invention also includes a detection component 5, which is disposed on the base 1 and located on the other side of the sliding seat 2, as shown in FIG5. The detection component 5 and one of the clamping components 4 are symmetrically distributed on both sides of the sliding seat 2.

[0048] The detection component 5 includes a second fixing member 51, a second movable member 52, a second spring 54, and a detection baffle 53. The second fixing member 51 is disposed on the base 1. The detection baffle 53 is fixedly connected to the side of the sliding seat 2. The second movable member 52 is located between the second fixing member 51 and the detection baffle 53, and the second movable member 52 is connected to the second fixing member 51 by the second spring 54. A detection space is formed between the detection baffle 53 and the second movable member 52. A connecting block 55 is disposed on the side of the detection baffle 53 facing the second movable member 52. The distance between the side of the connecting block 55 facing the second movable member 52 and the side of the detection baffle 53 facing the connecting block 55 is equal to the diameter of the smallest wire in the same clamping. A pressure sensor is disposed on the side of the connecting block 55 facing the second movable member 52.

[0049] The side of the second fixing member 51 facing the detection baffle 53 is flush with the side of the first movable member 42 of the symmetrical clamping assembly 4 facing the clamping block 43, and is in the same plane. The side of the detection baffle 53 facing the second movable member 52 is flush with the side of the clamping block 43 facing the first movable member 42, and is in the same plane.

[0050] It is easy to understand that the structure of the detection component 5 is basically the same as that of the symmetrical clamping component 4. The second movable part 52 also has guide posts on its side facing the second fixed part 51, and the second fixed part 51 also has guide through holes that cooperate with the guide posts. The difference between the detection component 5 and the clamping component 4 is that the detection component 5 has a connecting block 55 inside as a simulated wire to replace the actual wire. In production, the wire size can be obtained by online measurement equipment such as a camera. Based on the smallest wire size in the same batch of production, a connecting block 55 with a similar thickness is selected and installed on the detection baffle 53. During the wire clamping process, the clamping pressure is detected by the pressure sensor of the connecting block 55 to determine whether all wires are firmly clamped.

[0051] The usage method of detection component 5 is as follows:

[0052] When clamping and fixing the wire, the connecting block 55 moves towards the second movable part 52 and compresses the second spring 54. During this process, the pressure sensor of the connecting block 55 detects the pressure data. When the pressure data reaches the value required for clamping and fixing, it indicates that the multi-position wire adaptive clamp is firmly clamping multiple wires. The hydraulic drive device 3 stops driving the sliding seat 2 to move and keeps the wire clamped.

[0053] The value required for clamping and fixing refers to the clamping force required for clamping component 4 to firmly clamp the smallest size wire when clamping different specifications of wires simultaneously. It is easy to understand that when clamping component 4 can firmly fix the smallest size wire, other clamping components 4 can firmly clamp larger size wires.

[0054] Furthermore, in order to improve the automation of the multi-clamping wire adaptive fixture, the detection component 5 also includes an auxiliary hydraulic cylinder 56. The auxiliary hydraulic cylinder 56 is located on the side of the detection baffle 53 away from the second movable member 52. The piston rod of the auxiliary hydraulic cylinder 56 passes through the detection baffle 53 and is fixedly connected to the connecting block 55. That is, the connecting block 55 is driven to move by the auxiliary hydraulic cylinder 56.

[0055] The auxiliary hydraulic cylinder 56 drives the movement of the connecting block 55, thereby adjusting the size of the simulated wire. With the auxiliary hydraulic cylinder 56 installed, there is no need to replace the connecting block 55 to change the size of the simulated wire; instead, the size of the simulated wire is changed by moving the connecting block 55. Based on this, a device for detecting the wire thickness, such as a camera, can be installed in the space above the base 1. This is a common method for determining the size of objects. The camera faces the multiple clamping components 4 below, capturing the dimensions of all wires entering the first clamping station. The smallest dimension among these is then determined and used as the size of the simulated wire.

[0056] The improved method for using detection component 5 follows these steps:

[0057] Before multiple wires enter the first clamping station of the multi-clamping wire adaptive fixture, the wire size is detected online to determine the minimum size value of the wire.

[0058] Based on the minimum size value, the auxiliary hydraulic cylinder 56 drives the connecting block 55 to move, so that the distance between the side of the connecting block 55 facing the second movable member 52 and the side of the detection baffle 53 facing the connecting block 55 is equal to the minimum size value.

[0059] Subsequently, the hydraulic drive device 3 drives the sliding seat 2 to move, while clamping multiple wires. At the same time, the connecting block 55 applies pressure to the second movable part 52. When the pressure sensor detects that the pressure has reached the value required for clamping and fixing, it indicates that the multi-position wire adaptive clamp has firmly clamped multiple wires. The hydraulic drive device 3 stops driving the sliding seat 2 to move, and keeps the wires clamped.

[0060] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
