Description

Technical Field

[0001] This utility model relates to the field of material loading, and in particular to a device for assembling materials with concentricity. Background Technology

[0002] In assembly processes, it is often necessary to assemble two parts of different sizes. Multiple parameters must be considered to ensure the accuracy of the assembly. Concentricity, for example, is absolutely essential; otherwise, misalignment will prevent assembly, potentially rendering the parts unusable and compromising equipment safety. Therefore, ensuring the accuracy of concentricity during part assembly is a pressing technical problem that needs to be solved. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a device for assembling materials with concentricity, which can effectively ensure the concentricity of two materials of different sizes when clamping them.

[0004] This utility model is achieved through the following technical solution:

[0005] An apparatus for assembling components with concentricity, characterized in that it comprises:

[0006] The first clamping unit includes a first main clamping member and a first secondary clamping member, wherein the first main clamping member moves toward the first secondary clamping member to clamp the first material with a first concentricity;

[0007] The second clamping unit includes two second main clamping members. After the first clamping unit clamps the first material, both second main clamping members move toward the first material to clamp the first material with a second concentricity. The first concentricity and the second concentricity are coaxially arranged.

[0008] A distance adjustment unit is used to detect the movement distance of the second main clamping member in the direction perpendicular to the second concentricity. The distance adjustment unit is set in a one-to-one correspondence with the second main clamping member.

[0009] The rotary mounting unit, wherein both the first clamping unit and the second clamping unit are disposed on the rotary mounting unit.

[0010] Furthermore, both the first main clamping member and the first secondary clamping member have a first V-shaped abutment groove, the opening of which is oriented towards the first material.

[0011] Furthermore, the first clamping unit also includes a first locking member, which locks the first main clamping member after the first material is clamped.

[0012] Furthermore, both of the second main clamping members have a second V-shaped abutment groove, the opening of which is oriented toward the second material.

[0013] Furthermore, the second clamping unit includes a second locking member, which locks the corresponding second main clamping member after the second material is clamped.

[0014] Furthermore, the distance adjustment unit includes a helical distance measuring element and / or a distance sensor.

[0015] Furthermore, the rotary mounting unit includes an L-shaped mounting plate, and the first main clamping member and the second main clamping member are slidably disposed within the horizontal plane of the mounting plate.

[0016] Furthermore, the rotary mounting unit also includes a rotary shaft connected to an external device, the rotary shaft being slidably disposed on a vertical plane on the L-shaped mounting plate, and the rotary mounting unit also includes a detachable adjusting shaft, the first end of the adjusting shaft passing through the L-shaped mounting plate and then inserted into the rotary shaft, and the second end of the adjusting shaft engaging with the clamped first material, so that the adjusting shaft has a third concentricity coaxial with the first concentricity and the second concentricity.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] 1. After the first clamping unit clamps the first material, both second main clamping members move toward the first material to abut against it and clamp it. At this time, the two second main clamping members have a second concentricity, which is coaxial with the first concentricity. Combined with the spiral rangefinder, it can effectively ensure that the corresponding axes of the first and second materials being clamped are collinear, thereby ensuring their concentricity.

[0019] 2. The rotary mounting unit also includes a detachable adjusting shaft. The first end of the adjusting shaft passes through the L-shaped mounting plate and is inserted into the rotary shaft. The second end of the adjusting shaft engages with the clamped first workpiece. After adjustment, the rotary shaft has a third concentricity, coaxial with the first and second concentricities. The sliding of the rotary shaft is restricted, so that when moving to the next station, only the mutual positioning between the rotary shaft and the station is required to position the first and second workpieces.

[0025] like Figure 1 and Figure 2As shown, this embodiment discloses a device for assembling concentricity of parts, including a first clamping unit, a second clamping unit, a distance adjustment unit 4, and a rotary mounting unit. The first clamping unit and the second clamping unit are both disposed on the rotary mounting unit. After the first clamping unit and the second clamping unit clamp the first part and the second part respectively, they can be rotated to the corresponding work station, such as the welding work station.

[0026] In this embodiment, the first clamping unit includes a first main clamping member 1 and a first secondary clamping member 2. The first main clamping member 1 moves toward the first secondary clamping member 2 to clamp the first material with a first concentricity. Specifically, both the first main clamping member 1 and the first secondary clamping member 2 have a first V-shaped abutment groove 5, and the opening of the first V-shaped abutment groove 5 is set toward the first material.

[0027] In this embodiment, two second main clamping members 3 are provided, and the straight line of the movement trajectory of the two second main clamping units is parallel to the straight line of the movement trajectory of the first main clamping unit. Both second main clamping members 3 have a second V-shaped abutment groove 7, the opening of which faces the second material. After the first clamping unit clamps the first material, both second main clamping members 3 move towards the first material to abut against it and clamp it. At this time, the two second main clamping members have a second concentricity, which is coaxial with the first concentricity.

[0028] In this embodiment, the distance adjustment unit 4 is used to detect the movement distance of the second main clamping member 3 in the direction perpendicular to the second concentricity. The distance adjustment unit 4 is arranged in a one-to-one correspondence with the second main clamping member 3. The distance adjustment unit 4 includes a helical distance measuring element and / or a distance sensor. In this application, a helical distance measuring element is preferred. A screw extending along the movement direction is provided between the two second main clamping members 3, and the corresponding threads of the two second main clamping members are opposite, that is, when the screw is rotated, the two second main clamping members move towards each other or away from each other.

[0029] After the second concentricity is confirmed, the second clamping unit is held. The first clamping member first clamps the first workpiece, and then the diameter of the second workpiece is confirmed. For example, if the diameter of the second workpiece is 2cm larger than that of the first workpiece, the screw rod is rotated counterclockwise by 1.5cm using a helical distance measuring device. At this time, the relative distance between the two second main clamping members is 3cm. Then, it is rotated clockwise by 0.5cm, and the second workpiece can then be clamped.

[0030] It is worth noting that the first clamping unit also includes a first locking member 6, which locks the first main clamping member 1 after the first workpiece is clamped. The second clamping unit includes a second locking member 8, which locks the corresponding second main clamping member 3 after the second workpiece is clamped. Both the first locking member 6 and the second locking member 8 include locking screws.

[0031] The rotary mounting unit includes an L-shaped mounting plate 9, with a first main clamping member 1 and a second main clamping member 3 slidably disposed within the horizontal plane of the mounting plate. The rotary mounting unit also includes a rotary shaft 10 connected to external equipment, which is slidably disposed on a vertical plane of the L-shaped mounting plate 9.

[0032] It is worth noting that the rotary mounting unit also includes a detachable adjusting shaft. The first end of the adjusting shaft passes through the L-shaped mounting plate 9 and is inserted into the rotary shaft 10. The second end of the adjusting shaft engages with the clamped first workpiece. After adjustment, the rotary shaft 10 has a third concentricity, coaxial with the first and second concentricities. The sliding of the rotary shaft 10 is restricted, so that when moving to the next station, only the mutual positioning between the rotary shaft 10 and the station is required to position the first and second workpieces.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
