DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 5The utility model of the polishing machine for rounded corner grinding of the cylinder body of the continuous casting clamping cylinder comprises a base 1, a support column 2, a cantilever 3, a spindle box 4, a polishing disc 5, a support seat 6, a bearing 7, a chuck 8, and a rotary driver 9. One end of the support column 2 is fixed to the base 1, and one end of the cantilever 3 is matched with the support column 2. The cantilever 3 is slidably matched with the support column 2. The utility model also comprises a lifting drive mechanism, and the cantilever 3 is connected to the lifting drive mechanism. The surface of the support column 2 is provided with a sliding groove, and the sliding groove extends along the axial direction of the support column 2. The cantilever 3 is provided with a through hole, and the hole wall of the through hole is provided with a protrusion. The support column 2 passes through the through hole on the cantilever 3. When the cantilever 3 is lifted or lowered, the protrusion is slidably matched with the sliding groove, which not only plays a guiding role, but also prevents the cantilever 3 from rotating.

[0022] The lifting drive mechanism includes a motor 10 and a screw rod 11. The motor 10 is connected to the screw rod 11. A threaded hole is provided on the cantilever 3. The screw rod 11 is threadedly matched with the threaded hole on the cantilever 3. Since the cantilever 3 is restricted in the circumferential direction, the screw rod 11 and the cantilever 3 form a screw mechanism. When the motor 10 drives the screw rod 11 to rotate, the cantilever 3 is lifted and lowered by the action of the screw mechanism.

[0023] Although the lifting drive mechanism can overcome the gravity of the cantilever 3 and prevent the cantilever 3 from falling without operation, in order to reduce the burden of the lifting drive mechanism, in this embodiment, a preferred method is that a spring (the spring is not shown in the figure) is sleeved on the support column 2, one end of the spring abuts against the cantilever 3, and the other end of the spring abuts against the base 1 or the step provided on the support column 2. The support effect of the spring on the cantilever 3 reduces the burden of the lifting drive mechanism on the cantilever 3.

[0024] The spindle box 4 cooperates with the cantilever 3. In this embodiment, a slide rail 3a is provided on the cantilever 3, and the slide rail 3a extends along the transverse direction of the cantilever 3. A sliding groove is provided on the spindle box 4, and the sliding groove is slidably matched with the slide rail 3a, so that the spindle box 4 can move along the transverse direction of the cantilever 3.

[0025] A locking assembly 4a is provided on the spindle box 4, which consists of a handle and a locking shaft fixed to the handle. The locking shaft is threadedly connected to the spindle box 4. When the operator pushes the spindle box 4 to move horizontally along the cantilever 3 to a required position, the locking shaft is fed toward the cantilever 3 by rotating the handle, and finally the locking shaft and the cantilever 3 are abutted against each other, thereby locking the spindle box 4 on the cantilever 3.

[0026] The polishing disc 5 is fixed to the output end of the spindle box 4. The polishing disc 5 is used to grind the fillet of the continuous casting clamping cylinder body A. The structure of the polishing disc 5 is prior art and will not be described in detail here.

[0027] The support seat 6 is located below the polishing disk 5, and the support seat 6 is fixed to the base 1. The support seat 6 and the base 1 can be fixed by welding or other methods. For example, in this embodiment, a clamping mechanism is also included. The side wall of the support seat 6 is provided with a pressure block 6c, and the base 1 is provided with a T-slot 1a. The clamping mechanism passes through the T-slot 1a and is connected to the pressure block 6c.

[0028] The clamping mechanism includes a clamping plate 12, a screw rod 13, and a clamping nut 14. The clamping plate 12 is located in the T-slot 1a; one end of the screw rod 13 is fixed to the clamping plate 12; the other end of the screw rod 13 passes through the T-slot 1a and the pressure block 6c in turn and is connected to the clamping nut 14, so that the pressure block 6c is clamped between the clamping nut 14 and the base 1.

[0029] The groove wall surface of the T-shaped groove 1a is provided with a plurality of first teeth 1b, and a first tooth groove is formed between two adjacent first teeth 1b. The clamping plate 12 is provided with a plurality of second teeth 12a, and a second tooth groove is formed between two adjacent second teeth 12a. The first teeth 1b cooperate with the second tooth groove, and the second teeth 12a cooperate with the first tooth groove. This structure is equivalent to two racks meshing with each other. After the racks mesh with each other, a stable combination is formed for the clamping plate 12, so that the clamping plate 12 can resist the axial force generated during the processing to avoid the position of the support seat 6 from changing, thereby stabilizing the position of the support seat 6.

[0030] The support seat 6 is provided with a bearing mounting hole 6a and a receiving chamber 6b communicating with the bearing mounting hole 6a, the bearing 7 is matched with the bearing mounting hole 6a, the rotary driver 9 is located in the receiving chamber 6b and is fixed to the support seat 6, the chuck 8 is matched with the bearing 7, and one end of the chuck 8 passes through the bearing 7 and is connected to the rotary driver 9.
