Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical automation, in particular to a screw-locked correction mechanism. Background Art
[0002] Currently, all domestic screw machines suffer from the same problem: when the machine picks up the screw and reaches the locking point, the screw swings significantly, resulting in locking failure. These types of screw machines generally do not use a bottom camera to locate the screw position, making it impossible to ensure the concentricity of the screw on the screwdriver. This results in a generally low locking yield rate. Utility Model Content
[0003] In order to address the deficiencies in the prior art, the utility model provides a screw locking correction mechanism. The screw to be locked is placed between the "V-shaped" grooves of the two clamping jaws, which is adapted to the auxiliary guidance of screws of different sizes and shapes, improves the concentricity of the screw on the screwdriver, and puts the screw in the correct position before locking, thereby ensuring that the screw can be locked to the target position accurately and correctly, thereby improving the locking yield of the screw machine.
[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:
[0005] A correction mechanism for screw locking is arranged on one side of the screw machine. The correction mechanism includes two oppositely arranged jaws, a spacing adjustment mechanism for controlling the spacing between the two jaws, and a lifting mechanism for controlling the lifting and lowering of the jaws and the spacing adjustment mechanism. "V-shaped" grooves are provided on the opposite clamping surfaces of the two jaws, and the "V-shaped" grooves of the two jaws are located on the lower side of the screwdriver of the screw machine.
[0006] The clamping jaw includes a supporting portion connected to the spacing adjustment mechanism, an extending portion extending downward is provided at one end of the supporting portion away from the spacing adjustment mechanism, a clamping portion is provided at one end of the extending portion away from the supporting portion, and the "V-shaped" groove is provided on the clamping surface of the clamping portion.
[0007] The angle between the clamping portion and the supporting portion is an obtuse angle.
[0008] The included angle between the clamping portion and the supporting portion is 110° to 150°.
[0009] The lifting mechanism includes a lifting cylinder, the spacing adjustment mechanism is connected to the telescopic rod of the lifting cylinder via a support seat, and the support seat is slidably connected to the lifting cylinder.
[0010] The spacing adjustment mechanism includes a bidirectional linear module, and the two clamping jaws are respectively connected to the two sliding seats of the bidirectional linear module.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The correction mechanism of the utility model is low-priced. During the screw locking operation, the screw to be locked is placed between the "V-shaped" grooves of the two clamping jaws, which is suitable for auxiliary guidance of screws of different sizes and shapes, improves the concentricity of the screw on the screwdriver, and puts the screw in the correct position before locking, so as to ensure that the screw can be locked to the target position accurately and improve the locking yield of the screw machine. In actual application, the locking yield can be increased from 70% to 98%.
[0013] 2. The clamping jaw of the utility model includes a supporting portion, a downwardly extending extending portion, and a clamping portion which are connected in sequence. A "V-shaped" groove is provided on the clamping surface of the clamping portion. While ensuring the strength and durability of the clamping jaw, the clamping jaw can provide better stability and flexibility when clamping screws, and provide sufficient space for the screwdriver of the screw machine to facilitate the locking operation of the screwdriver.

[0020] like Figure 1 、 Figure 2 As shown, the present invention provides a screw tightening correction mechanism, which is disposed on one side of a screw machine 5 and is used to adjust and correct the position of a screw 4 to be tightened during the screw tightening process. The correction mechanism includes two opposing clamping jaws 1, a spacing adjustment mechanism 2 for controlling the spacing between the two clamping jaws 1, and a lifting mechanism 3 for controlling the elevation of the clamping jaws 1 and the spacing adjustment mechanism 2. The opposing clamping surfaces 14 of the two clamping jaws 1 are each provided with a "V-shaped" groove 10, which is located on the underside of the screwdriver 51 of the screw machine 5.
[0021] The present invention's correction mechanism is inexpensive and, when used with a screw machine, places the screw 4 to be fastened between the "V-shaped" grooves 10 of the two clamping jaws 1 to adjust the angle of the screw 4, thereby assisting in guiding the screw 4 and improving the concentricity of the screw 4 on the screwdriver 51. This ensures that the screw 4 is correctly positioned before fastening, ensuring that the screw 4 can be accurately fastened to the target position and improving the fastening yield of the screw machine 5.
