Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant castings, in particular to a wear-resistant casting processing positioning device. Background Art

[0002] A casting is a metal shaped object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain an object with a certain shape, size and performance. When the casting is polished and processed, it is necessary to use a positioning device to fix the casting to prevent the casting from shifting.

[0003] For example, the public document with application number 202020977653.6 discloses a wear-resistant casting processing positioning device, the utility model enables two racks to stably fix flat wear-resistant castings or wear-resistant castings with uneven shapes, thereby avoiding the uneven shapes of existing wear-resistant castings. Usually, the existing wear-resistant casting processing positioning devices are unable to stably position wear-resistant castings with uneven flatness, affecting the processing efficiency of the processing personnel. When processing the wear-resistant casting on the wear-resistant casting processing positioning device, the user needs to move the processing, which is time-consuming and labor-intensive, affecting the work efficiency of the processing personnel. However, the wear-resistant casting processing positioning device presses down the casting in the frame from above to position it, which will occupy a certain spatial position above the casting, thereby affecting the range of casting processing, and this positioning method is also difficult to ensure that the casting is centered, and there is a certain deviation in the positioning of the workpiece, which will affect the accuracy of the workpiece processing of the casting and affect the casting processing quality.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a wear-resistant casting processing positioning device is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a wear-resistant casting processing positioning device includes a placement plate 1, and assembly parts 2 are fixedly provided on both ends of the placement plate 1. Four sliding grooves 3 are evenly distributed above the surface of the placement plate 1, and a positioning mechanism 4 is provided inside the sliding groove 3. A locking mechanism 5 is provided in the middle below the surface of the placement plate 1.

[0024] By adopting the above technical solution, the positioning mechanism 4 is used to ensure that the casting is located at the center of the placement plate 1 for fixed positioning; at the same time, the locking mechanism 5 can fix the positioning mechanism 4 to prevent the positioning mechanism 4 from loosening.

[0025] Furthermore, the positioning mechanism 4 includes a screw rod 401 rotatably mounted on the inner surface of the sliding groove 3 , a moving block 402 is threadedly connected to the surface of the screw rod 401 , a clamping plate 403 is fixedly mounted on the upper end of the moving block 402 , and the moving block 402 slides against the inner surface of the sliding groove 3 .

[0026] By adopting the above technical solution, the screw rod 401 rotates, and under the limit of the moving block 402 by the sliding groove 3, the moving block 402 is pushed by the thread to drive the clamping plate 403 to move synchronously, so as to position and clamp the casting.

[0027] Furthermore, the positioning mechanism 4 also includes a driven bevel gear 404 fixedly arranged at one end opposite to the screw rod 401, and the same driving bevel gear 405 is meshedly arranged below the surface of the driven bevel gear 404. A handwheel rod 406 is fixedly arranged at the bottom end of the driving bevel gear 405, and the lower end of the handwheel rod 406 rotates to pass through the bottom of the placement plate 1.

[0028] By adopting the above technical solution, the handwheel rod 406 can drive the active bevel gear 405 to rotate, thereby synchronously driving the four driven bevel gears 404 to rotate synchronously, so that the four screw rods 401 maintain a consistent rotation rate, so that the moving distance and rate of the four moving blocks 402 can be the same, ensuring that the four clamping plates 403 simultaneously and synchronously clamp the four corners of the casting and push the casting to the center.

[0029] like Figure 2-Figure 4 As shown, the locking mechanism 5 includes positioning holes 501 evenly distributed around the handwheel rod 406 penetration position below the surface of the placement plate 1, and a movable rod 502 is slidably inserted in a certain hole position of the positioning holes 501, and the lower end of the movable rod 502 slides through the handwheel rod 406.

[0030] By adopting the above technical solution, the positioning hole 501 limits the movable rod 502, and the movable rod 502 passes through the handwheel rod 406, that is, when the movable rod 502 is inserted into the positioning hole 501, the handwheel rod 406 cannot rotate, and the handwheel rod 406 can rotate only when the positioning hole 501 is pulled out.

[0031] Furthermore, the locking mechanism 5 also includes a fixed plate 503 fixedly installed above the surface of the movable rod 502, a spring 504 fixedly installed on the lower surface of the fixed plate 503, and the spring 504 is sleeved on the outer side of the movable rod 502, and the bottom end of the spring 504 is fixedly connected to the surface of the handwheel rod 406.

[0032] By adopting the above technical solution, the diameter of the fixing plate 503 is larger than the hole through which the movable rod 502 passes through the handwheel rod 406, thereby preventing the movable rod 502 from being pulled too much and falling off;

[0033] The spring 504 provides an upward pushing force to the movable rod 502 through the fixing plate 503 , so that the movable rod 502 can be stably inserted into the positioning hole 501 .

[0034] Furthermore, a bolt 6 is threadedly connected through the middle of the surface of the clamping plate 403 , and a push plate 7 is fixedly provided at one end of the bolt 6 close to the inner side of the clamping plate 403 .

[0035] By adopting the above technical solution, the push plate 7 can be further extended by rotating the bolt 6, so that the clamping plate 403 can also position the special-shaped casting.

[0036] Working principle: When using the wear-resistant casting processing positioning device, first, the casting is roughly placed on the middle of the placement plate 1, and then the movable rod 502 is pulled downward to move out of the positioning hole 501. At this time, the handwheel rod 406 can be turned to rotate the active bevel gear 405, driving the four driven bevel gears 404 to rotate synchronously, so that the four screw rods 401 can rotate at the same frequency. Under the limitation of the sliding groove 3, the four moving blocks 402 drive the four clamping plates 403 to move synchronously and at the same speed toward the middle, so that the regular casting is centered and fixed, and for irregular special-shaped castings, the two most protruding sides of the casting are clamped by the clamping plates 4 03 After clamping, the clamping plate 403 cannot move. At this time, rotating the bolt 6 can push the push plate 7 to extend further inward, and further position the shorter sides of the casting, thereby ensuring that the special-shaped casting can also be effectively positioned and fixed. After the entire casting is fixed, loosen the movable rod 502, and under the elastic force of the spring 504, the movable rod 502 is pushed through the fixed plate 503 to insert into the nearest positioning hole 501, thereby fixing the handwheel rod 406, that is, fixing the entire positioning mechanism 4, and stably positioning and fixing the casting in the center. This is the working principle of the wear-resistant casting processing positioning device.
