Detailed Description

The invention is described in detail below with reference to the figures and the specific embodiments.

As shown in fig. 2, the precise positioning stepper comprises a track 4, a moving frame 3 and a driving mechanism for driving the moving frame 3 to reciprocate on the track 4, wherein the track 4 and the moving frame 3 are both horizontally arranged. The driving mechanism 5 comprises a motor 501, a transmission chain 502, a driving chain wheel 503 and a driven chain wheel 504, the driving chain wheel 503 and the driven chain wheel 504 are respectively arranged at two ends of the track 4, the motor 501 is in transmission connection with the driving chain wheel 503, one end of the transmission chain 502 is fixedly connected with the movable frame 3 after bypassing the driving chain wheel 503, and the other end of the transmission chain 502 is fixedly connected with the movable frame 3 after bypassing the driven chain wheel 504. The driving sprocket 503 rotates forward and backward to drive the moving frame 3 to reciprocate on the track 4.

Remove and be provided with on the frame 3 and be used for blocking preceding fender subassembly 1 of kiln car front end and be used for blocking the backstop subassembly 2 of kiln car rear end, preceding fender subassembly 1 includes sliding seat 101, preceding baffle 102, cylinder 103 and fender flat board 104, preceding baffle 102 is articulated with sliding seat 101 through first articulated shaft 105, the cylinder body and the 3 fixed connection of removal frame of cylinder 103, the telescopic link and the sliding seat 101 fixed connection of cylinder 103, keep off flat board 104 and set up in cylinder 103 top, keep off flat board 104's both ends respectively through two first connecting plate 106 and removal frame 3 fixed connection, keep off flat board 104 level setting, two connecting plates 106 respectively with keep off flat board 104 vertical fixation and be connected, preceding baffle 102 sets up between keeping off flat board 104 and backstop subassembly 2. The front baffle plate 102 is in a right triangle shape, and when the kiln car is not fixed, the side wall surface where the bevel edge of the front baffle plate 102 of the right triangle is located is abutted against the lower wall surface of the baffle plate 104.

The rear baffle assembly 2 comprises a base 201 and two rear baffles 202, the rear baffles 202 are hinged to the base 201 through second hinge shafts 203, the base 201 is fixedly connected with the movable frame 3, and one ends of the rear baffles 202 far away from the front baffle 102 are fixedly connected with balancing weights 204. The two back boards 202 are both in the shape of a right triangle, and the two back boards 202 are fixedly connected by a second connecting plate 205.
