Description

Technical Field

[0001] This utility model relates to the field of non-standard workpiece processing technology, specifically to an adjustable V-block positioning device for non-standard workpieces. Background Technology

[0002] In the machinery manufacturing industry, the manufacturing process of forged and cast parts often results in large dimensional tolerances due to factors such as material properties and process control. These dimensional tolerances make it difficult to ensure consistent positioning of each part during subsequent machining, especially during positioning and installation in fixtures. Positioning and clamping non-standard workpieces is more challenging than that of standard workpieces.

[0003] Chinese utility model patent with announcement number CN222902708U discloses a positioning clamp, which includes "a positioning post connected to the receiving plate, the positioning post being located in the V-groove, and the positioning post being used for inserting parts"; however, the V-groove structure of this device is fixed, and it can only position and clamp parts of a specific size. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable V-block positioning device for non-standard workpieces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable V-block positioning device for non-standard workpieces, comprising a base, a groove formed at the top center of the base, clamping plates rotatably connected to the inner walls of opposite sides of the groove, a limiting plate movably sleeved on one side of the clamping plate, and an angle adjustment mechanism rotatably connected to the clamping plate through the side wall of the groove to the outside, the two clamping plates being symmetrically distributed about the central axis of the groove, and the dimensions of the groove being consistent with the sum of the dimensions of the two clamping plates; The angle adjustment mechanism includes a servo motor.

A clamping plate is fixedly connected to the inner wall of the center of the main gear and the driven gear.

[0006] The beneficial effects of this utility model are as follows: with the combination of servo motor, rotating shaft, half gear, main gear, driven gear and clamping plate, the included angle of two clamping plates arranged in a V shape can be adjusted to adapt to non-standard workpieces of different sizes. Furthermore, the combination of limiting plate and limiting pin can keep the angle of the V-shaped clamping plates stable.

[0007] To achieve adjustable included angles for the V-shaped clamps: The configuration is further defined as follows: the servo motor, half gear, main gear, and driven gear constitute a transmission structure, and the angle adjustment range of a single clamping plate is zero to ninety degrees.

[0008] By adopting the above technical solution, the included angle of the V-shaped clamps can be adjusted.

[0009] To ensure the stability of the included angle of the V-shaped clamps: The clamping plate is further configured such that: the clamping plate includes a clamping plate body, and a limiting pin is provided in the middle of the side wall of the clamping plate body.

[0010] By adopting the above technical solution, the included angle of the V-shaped clamps can be kept fixed.

[0019] Please see Figures 1 to 4 An adjustable V-block positioning device for non-standard workpieces includes a base 1, a groove 2 is provided at the top center of the base 1, clamping plates 3 are rotatably connected to the inner walls of opposite sides of the groove 2, a limit plate 4 is movably sleeved on one side of the clamping plate 3, and an angle adjustment mechanism 5 is rotatably connected to the clamping plate 3 through the side wall of the groove 2 to the outside. The two clamping plates 3 are symmetrically distributed about the central axis of the groove 2, and the size of the groove 2 is consistent with the sum of the sizes of the two clamping plates 3. The angle adjustment mechanism 5 includes a servo motor 501. One end of the output shaft of the servo motor 501 is fixedly connected to a rotating shaft 502 via a coupling. One end of the rotating shaft 502 is rotatably connected to the outer wall of one side of the base 1. A half gear 503 is fixedly connected to the outside of the rotating shaft 502. A main gear 504 is meshed with the outer wall of the half gear 503. A driven gear 505 is meshed with the outer wall of the main gear 504. A clamping plate 3 is fixedly connected to the inner wall of the center of the main gear 504 and the driven gear 505.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the servo motor 501, half gear 503, main gear 504 and driven gear 505 constitute the transmission structure, and the angle adjustment range of a single clamping plate 3 is from zero to ninety degrees.

[0021] In this embodiment, as Figure 3 As shown, the clamping plate 3 includes a clamping plate body 301, and a limiting pin 302 is provided in the middle of the side wall of the clamping plate body 301.

[0024] The working process of this adjustable V-block positioning device for non-standard workpieces is as follows: First, the base 1 is fixed on a stable machine tool with bolts. The servo motor 501 (model: HGKR43JK) is started to drive the rotating shaft 502 to rotate, which in turn drives the half gear 503 to rotate. This drives the main gear 504 and one of the clamping plates 301 to rotate. Through the meshing driven gear 505, the other clamping plate 301 is driven to rotate, so that the two clamping plates 301 can rotate to a suitable angle for workpiece processing. After the angle is suitable, the limiting hole 402 of the limiting plate 401 is sleeved with the limiting pin 302 of the two clamping plates 301, so that the included angle between the two clamping plates 301 arranged in a V shape can be kept stable.
