Detailed Description

The embodiment of the application discloses clamping and positioning structure of small-sized grinding machine. Referring to fig. 1, the clamping and positioning structure of the small-sized grinding machine includes a connecting rod 2 connected to a grinding machine body 1, and the connecting rod 2 is horizontally disposed and extends in a direction away from the grinding machine body 1. Connecting rod 2 goes up the slip and is provided with two sets of fixed subassemblies 3, and fixed subassembly 3 includes the butt piece 31 with connecting rod 2 sliding connection. As an embodiment of the sliding connection between the abutting block 31 and the connecting rod 2, referring to fig. 2, the two vertical side surfaces of the abutting block 31 are provided with sliding grooves 314 for penetrating the connecting rod 2, so that the abutting block 31 can slide along the length direction of the connecting rod 2 and can rotate along the vertical direction.

The abutting block 31 is provided with a first connecting hole 313 in threaded connection with the positioning member 32, and the positioning member 32 is abutted to the connecting rod 2 by screwing the positioning member 32, so as to position the abutting block 31.

Because the two groups of fixing components 3 are arranged on the connecting rod 2, when a rod-shaped workpiece such as a mold thimble is fixed, the two fixing components 3 are respectively abutted against the upper end and the lower end of the workpiece. And because the grinding machine body 1 carries on spacingly to the front end of work piece, consequently make two fixed subassemblies 3 carry out the centre gripping to the tail end of work piece, guarantee the stability of work piece. Therefore, the workpiece is not easy to move in the machining process, the machining position is not easy to change, and the machining quality of the workpiece is improved.

Referring to fig. 2, a horizontal surface of the end of the abutting block 31 away from the connecting rod 2 is provided with a receiving groove 311. In the present embodiment, when the abutment block 31 is rotated to the horizontal position, two surfaces of the abutment block 31 parallel to the horizontal plane are horizontal surfaces of the abutment block 31. The length direction of the receiving groove 311 is parallel to the length direction of the coupler shaft 2. When fixing the rod-shaped workpiece, the workpiece is inserted into the receiving groove 311. The receiving groove 311 increases the contact area between the workpiece and the abutment block 31, thereby increasing the frictional force between the workpiece and the abutment block 31, and making the workpiece less likely to move. The surface of the abutting block 31 on the side away from the accommodating groove 311 is provided with a spare groove 312, and the spare groove 312 facilitates the abutting block 31 to position the workpiece.

Referring to fig. 2, the connecting rod 2 is slidably provided with a limiting block 4, and the limiting block 4 is located on one side of the two sets of fixing assemblies 3 away from the grinding machine body 1. As an implementation mode of the sliding connection between the limiting block 4 and the connecting rod 2, a sliding groove 47 for penetrating the connecting rod 2 is arranged in the limiting block 4, and the axis of the sliding groove 47 is collinear with the axis of the sliding groove 314. When the limiting block 4 moves, the limiting block can slide along the length direction of the connecting rod 2 and can rotate along the vertical direction. The limiting block 4 is provided with a second connecting hole 41, and a fixing piece 42 is connected to the second connecting hole 41 through threads. In the present embodiment, the fixing member 42 is provided as a screw, and the second coupling hole 41 is provided as a screw hole. By screwing the fixing member 42, the fixing member 42 abuts against the connecting rod 2, and the stopper 4 is positioned.

Referring to fig. 2, one end of the limiting block 4 away from the connecting rod 2 is slidably provided with a limiting rod 43, and the length direction of the limiting rod 43 is parallel to the length direction of the connecting rod 2. The limiting rod 43 is moved, and the limiting rod 43 is close to or far away from the grinding machine body 1. The limiting block 4 is provided with a third connecting hole 44, and a limiting piece 45 is connected to the third connecting hole 44 through a screw thread. In the present embodiment, the stopper 45 is provided as a screw, and the third connection hole 44 is provided as a screw hole. By screwing the limiting member 45, the limiting member 45 abuts against the limiting rod 43, and the limiting rod 43 is positioned in the limiting block 4.

Referring to fig. 2, one end of the limiting rod 43 close to the grinding machine body 1 is connected with a clamping block 46, and the clamping block 46 is rectangular block-shaped as a whole. When the limiting rod 43 slides in the direction away from the grinding machine body 1, the limiting rod 43 cannot continue to slide after the clamping block 46 abuts against the limiting block 4.

The implementation principle of the clamping and positioning structure of the small grinding machine in the embodiment of the application is as follows: the worker screws the positioning member 32 to allow the abutment block 31 to freely rotate and slide on the connecting rod 2. The workpiece is then placed into the grinding machine body 1, and the two abutment blocks 31 are slid to the trailing ends of the workpiece, respectively. The lower end of the workpiece is inserted into the receiving groove 311, the upper end of the workpiece is inserted into the spare groove 312 of the other abutting block 31, and then the two positioning members 32 are screwed, respectively. After the two positioning pieces 32 are abutted to the connecting rod 2, the two abutting blocks 31 are not easy to rotate, and the workpiece is fixed. And finally, sliding the limiting block 4 to enable the tail end of the workpiece to abut against the clamping block 46 to limit the axial movement of the workpiece.
