Description

Technical Field

[0001] The utility model relates to the technical field of electrode cap grinding, in particular to a welding clamp grinding device. Background Art

[0002] A welding clamp dresser, also known as an electrode cap dresser, is a tool for grinding electrode caps. The structure of the dresser can be found in documents such as CN110170902A and CN205996377U. The dresser generally includes a bracket and a dresser. The dresser is composed of a motor, a tool holder, a transmission device, and a blade. The applicant has found that existing dressers are directly fixed on the bracket and cannot adjust the angle of the tool holder. In order to increase the grinding angle, some manufacturers have even set up horizontal and vertical tool holders to respectively mount two blades, which complicates the transmission structure of the motor and needs to be improved. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the present utility model is to provide a welding clamp dresser.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] A welding clamp grinder comprises a base and a grinder, wherein a telescopic cylinder is vertically mounted on the base, a mounting seat is fixedly connected to the piston rod of the telescopic cylinder, a rotating shaft is rotatably mounted in the mounting seat, the rotating shaft is horizontally arranged, and discs are fixedly connected to both axial ends of the rotating shaft, the discs and the rotating shaft are coaxially arranged, a grinder is mounted on the end surface of one of the discs facing away from the other disc through a floating compensation mechanism, a support plate is fixedly connected to the base below each disc, the support plate is vertically arranged and parallel to the disc, a receiving groove matching the disc shape is provided on the top of the support plate, and when the telescopic cylinder retracts, the two discs are respectively pressed against the two receiving grooves.

[0006] Furthermore, anti-slip grooves are provided on the side surface of the disc and the arc surface of the accommodating groove.

[0007] Furthermore, the grinder includes a motor, a tool holder and a blade. The motor is installed on the end face of one of the discs through a floating compensation mechanism. The motor is arranged perpendicular to the rotating shaft. The tool holder is fixed to the outer shell of the motor. The blade is rotatably installed on the tool holder and the blade is set deviated from the main shaft of the motor. The blade is connected to the main shaft of the motor in a transmission manner.

[0008] Further, the floating compensation mechanism includes two pairs of fixed seats, two guide rods, springs and a sliding seat. Two pairs of fixed seats are fixedly connected to the end face of one of the discs. A guide rod is installed in each pair of fixed seats. The guide rod is perpendicular to the axial direction of the disc. The sliding seat is fixedly connected to the outer shell of the motor. The sliding seat is slidably installed on the two guide rods. Springs are provided between the sliding seat and each fixed seat.

[0009] The beneficial effects of the present utility model are as follows: When the disc leaves the receiving groove, the rotating shaft can be rotated, so as to change the angle of the grinding device, realizing rapid adjustment. After the adjustment is completed, the telescopic cylinder is driven to retract, and the disc can be fixed. The structure is simple and has high stability. Compared with the traditional welding tong grinding device, it has higher applicability. Description of the Drawings

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model belong to the protection scope of the present utility model.

[0015] Such as Figures 1-3As shown in the figure, a welding pliers grinder includes a base 1 and a grinder. A telescopic cylinder 2 is vertically installed on the base 1. A mounting seat is fixedly connected to the piston rod of the telescopic cylinder 2. The mounting seat is composed of an upper mounting block 3 and a lower mounting block 4 which are separately arranged. The lower mounting block 4 is fixedly connected to the piston rod of the telescopic cylinder 2. The upper mounting block 3 is fixedly connected to the top of the lower mounting block 4 by bolts. A rotating shaft 5 is rotatably installed between the upper mounting block 3 and the lower mounting block 4. The rotating shaft 5 is horizontally arranged. Discs 51 are fixedly connected to both axial ends of the rotating shaft 5. The discs 51 are coaxially arranged with the rotating shaft 5. A grinder is installed on the end face of the disc 51 at the front end of the rotating shaft 5 through a floating compensation mechanism. Specifically, the grinder includes a motor 6, a tool holder 7 and a blade 8. The tool holder 7 is fixedly connected to the outer shell of the motor 6. The blade 8 is rotatably installed on the tool holder 7 and the blade 8 deviates from the main shaft of the motor 6. The blade 8 is in transmission connection with the main shaft of the motor 6 (this is the prior art, and the transmission structure disclosed in CN110170902A can be referred to). The floating compensation mechanism includes two pairs of fixed seats 52, two guide rods 9, springs 10 and a sliding seat 61.
