Description

Technical Field

[0001] The utility model belongs to the technical field of screw machines, and in particular relates to a screw locking mechanism for an auxiliary screw machine. Background Art

[0002] Screw machines are currently widely used in industrial processing, which saves a lot of labor costs; and compared with manual operations, the use of screw machines also greatly reduces the problem of errors and omissions in screw locking. At the same time, the technical difficulties of screw machines are gradually revealed. After the electric screwdriver in the screw machine sucks the screw, when it goes to the locking position to lock it, the screw, especially the screw with a washer, may shift and fall off, resulting in abnormal product locking, which directly affects the product quality and even has the risk of product scrapping; the screw machine has high requirements on the size of the electric screwdriver. A screw machine will use the same size of electric screwdriver and screw bit, so it is relatively troublesome for later maintenance.

[0003] The previously used screw machine sleeve structure had each part tightly fitted together, so it could not be adjusted according to the length of the screw bit, which affected the setting of the locking height when the screw machine was locking; only a small part of the contact surface with the screw was in contact, which made it difficult to set the vacuum value when the screw was adsorbed, and it could not ensure that the screw was vertical when locked. The above problems directly affected the quality of the screw machine's screw locking and the convenience of maintenance personnel in the later maintenance of the screw machine.

[0004] Therefore, there is an urgent need for an auxiliary screw machine screw locking mechanism to solve the above technical problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: an auxiliary screw machine screw locking mechanism, including a sleeve 1, a sleeve 2 4, a sleeve 3 6 and a suction nozzle 7; the sleeve 1 and the sleeve 2 4 are assembled and connected via a large screw ring 2 and a small screw ring 3; the sleeve 2 4 and the suction nozzle 7 are connected via a sleeve 3 6; a spring 5 is arranged inside the sleeve 2 4, the sleeve 3 6 and the suction nozzle 7.

[0024] When the screw machine adsorbs screws, it needs to be used in conjunction with an electric screwdriver. The locking mechanism of the utility model is used for the screw machine. The sleeve 1 is used to install the electric screwdriver of the screw machine so that the locking mechanism and the electric screwdriver are connected.

[0025] The sleeve 1 is provided with an electric screwdriver thread ring 101, a groove 102 and an electric screwdriver thread ring 2 103; the electric screwdriver thread ring 101 and the electric screwdriver thread ring 2 103 are respectively arranged at the upper and lower ends of the sleeve 1; the groove 102 is arranged at both ends of the sleeve 1, and the sleeve 1 is located at the lower end of the electric screwdriver thread ring 101.

[0026] The sleeve 1 is connected to the screwdriver through the screwdriver thread ring 103, so the assembly is simpler and more convenient.

[0027] The groove 102 facilitates installation between structures and avoids over-tight installation resulting in inability to open.

[0028] The electric screwdriver thread ring 101 has a large number of thread rings and can be compatible with more electric screwdriver bits of different lengths, thereby improving the applicability of the sleeve 1 structure.

[0029] The large screw ring 2 and the small screw ring 3 are arranged between the sleeve 1 and the sleeve 2 4, so as to separate the sleeve 1 and the sleeve 2 4, so as to adjust the screw bits of different lengths of the electric screwdriver. At the same time, the large screw ring 2 and the small screw ring 3 can fix and limit the sleeve 2 4.

[0030] The large screw ring 2 is arranged above the small screw ring 3, and is used to fix the position of the sleeve 1 and the electric screwdriver to prevent the sleeve 1 and the electric screwdriver from moving upward during the locking process.

[0031] The small screw ring 3 is used to limit the position of the sleeve 2 4 to prevent the sleeve 2 4 from rotating upward to shorten the length of the sleeve 2 4 during use.

[0032] The sleeve 4 is provided with a sleeve thread 1 401, a sleeve thread 2 402, a mounting portion 1 403 and a connecting piece 404; the sleeve thread 1 401 and the sleeve thread 2 402 are respectively arranged at the upper and lower ends of the sleeve 4; the mounting portion 1 403 is arranged at the lower end of the sleeve 4; the connecting piece 404 is arranged on the inner side of the mounting portion 1 403.

[0033] In order to ensure the automation of the screw machine, in actual use, the screw machine is often connected to a solenoid valve. The sleeve 2 4 of the utility model is connected to the solenoid valve via a connector 404, so as to control the adsorption of the screw, and the connector 404 is a component with relatively high sealing requirements, and air is sucked or blown through the connector 404, so that the lower end component moves automatically.

[0034] The sleeve thread 2 402 at the upper end of the sleeve 2 4 and the electric screw thread ring 101 at the lower end of the sleeve 1 1 are used to connect the sleeve 1 1; the sleeve thread 1 401 at the lower end of the sleeve 2 4 is used to connect the sleeve 3 6.

[0035] The installation portion 1 403 is an inwardly recessed structure, which facilitates the installation of the sleeve 2 4 .

[0036] When in use, the depth between the electric screwdriver thread circle 101 and the sleeve thread 2 402 between the sleeve 1 1 and the sleeve 2 4 can be used to cope with electric screwdriver bits of different lengths, and the screws adjusted to the level above the gasket can be inside the suction nozzle 7.

[0037] The sleeve three 6 is provided with a mounting portion two 601, a sleeve thread three 602 and a step 603; the mounting portion two 601 and the sleeve thread three 602 are respectively arranged at the upper and lower ends of the sleeve three 6; the step 603 is arranged at the bottom of the sleeve three 6.

[0038] The sleeve three 6 is used to connect the suction nozzle 7 and the sleeve two 4, and at the same time plays a certain guiding role for the up and down movement of the suction nozzle 7, thereby preventing the suction nozzle 7 from tilting and failing to suck the screws.

[0039] The setting of the mounting portion 2 601 facilitates the installation between the suction nozzle 7; the sleeve thread 3 602 at the upper end of the sleeve 3 6 and the sleeve thread 1 401 at the lower end of the sleeve 2 4 are used for the connection between the sleeve 3 6 and the sleeve 2 4.

[0040] The suction nozzle 7 is provided with a mounting portion 3 701 and a suction portion 702; the mounting portion 3 701 is arranged at the upper end of the suction nozzle 7, and the mounting portion 3 701 and the step 603 restrict each other, thereby preventing the suction nozzle 7 from falling while ensuring that the suction nozzle 7 can move up and down.

[0041] The adsorption part 702 is arranged at the lower end of the suction nozzle 7, and is used to absorb the screw. The adsorption part 702 contacts and absorbs the screw, which can effectively prevent the screw from being adsorbed crookedly, reduce the product defect rate, and improve the quality of locking. At the same time, the adsorption part 702 can adsorb all structures above the screw gasket into the sleeve of the suction nozzle 7, so that the screw can be adsorbed vertically, avoiding abnormal adsorption of the screw.

[0042] Specifically, one end of the spring 5 is placed in the suction nozzle 7, and the other end of the spring 5 resists the electric screwdriver. When installing, the electric screwdriver head passes through the middle of the spring 5, which also gives elasticity to the movement of the suction nozzle 7, preventing the suction nozzle 7 from moving downward too fast and damaging the components near the screw.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
