Detailed Description
The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.
Referring to fig. 1 to 5, the utility model discloses a prevent mark device that nut missed screwing up, including the support 2 of fixed block 1 and one end joint on fixed block 1 that links to each other with the machine of screwing up, can realize through fixed block 1 with the synchronous work of the machine of screwing up. The other end of the bracket 2 is provided with a guide mechanism, the guide mechanism comprises two guide screws 3, the stability of the movement process of the guide screws 3 is favorably kept, and the movement direction of the guide screws 3 is opposite to that of the tightening machine. The top of the guide screw rod 3 is inserted and installed on the support 2, the top end of the guide screw rod 3 is screwed with the nut 8, the bottom of the guide screw rod 3 is provided with a seal fixing block 5, the periphery of the guide screw rod 3 is sleeved with a spring 4, two ends of the spring 4 respectively tightly push against the bottom surface of the support 2 and the top surface of the seal fixing block 5, the seal 6 is arranged on the seal fixing block 5, the lower end surface of the seal 6 can be pressed to the corresponding position of the cylinder cover by utilizing the compression deformation of the spring 4 and the precompression force of the guide mechanism, and therefore marks are printed on.
