Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and specifically to a clamping device for casting processing. Background Technology

[0002] In the casting process, a clamping device is needed to hold the casting in place. A search revealed a patent with authorization announcement number CN216883539U, entitled "A Clamping Device for Metal Casting Production and Processing," which includes a horizontal plate. The top of the horizontal plate has fixing grooves on both sides, and fixing blocks are slidably connected inside each of the two fixing grooves. First clamping members are fixedly connected to the top of each of the two fixing blocks, and first elastic members are fixedly connected to opposite sides of each of the two fixing blocks. Stabilizing grooves are formed on the top of each of the two first clamping members, and second elastic members are fixedly connected to the bottom of the inner wall of the stabilizing grooves. Second clamping members are fixedly connected to the top of the second elastic members, and first fixing holes are formed on the front of each of the two fixing blocks. This clamping device for metal casting production and processing can quickly and conveniently clamp and fix metal castings during production and processing, is easy to place and remove, and can be adjusted according to the length and thickness of the metal casting, thus better and faster ensuring the production and processing of metal castings of different lengths and thicknesses. However, in actual use, the clamping device for metal casting production and processing fixes two clamping parts by fixing rods. Since the fixing rods have low self-adjustment during the fixing process, the stability is poor when clamping castings of different shapes. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a clamping device for casting processing.

[0004] The technical solution adopted by this utility model to solve its technical problem is a clamping device for casting processing, including a base. A first hydraulic cylinder is fixed to the top of the base. A support plate is fixed to the top of the piston rod of the first hydraulic cylinder. A baffle and a stop are fixed to the top of the support plate. A second hydraulic cylinder is fixed to the side of the baffle away from the stop. A clamping block is fixed to the piston rod of the second hydraulic cylinder. A motor is fixed to one side of the stop. The output shaft of the motor is connected to a double-acting screw through a coupling. Two locking blocks are provided above the support plate. Each locking block has a screw hole adapted to the double-acting screw. The side of the stop near the clamping block has two sliding grooves for the locking blocks to slide. Each sliding groove has a guide rod. Both guide rods are connected to the stop. Each locking block has a through hole adapted to the guide rod. Limiting mechanisms are fixed to the top of the clamping block and the stop.

[0005] By adopting the above technical solution, the casting is placed on the top of the support plate, so that the casting is located between the clamping block and the stop. The piston rod of the second hydraulic cylinder drives the clamping block to move towards the stop. The clamping block and the stop are in close contact with the casting, which can fix the casting from both sides. The output shaft of the motor drives the bidirectional lead screw to rotate, and the two clamping blocks move towards each other. The two clamping blocks can clamp the casting from the other two sides. It can not only clamp castings of different lengths and widths, but also improve the fixing effect. The piston rod of the first hydraulic cylinder drives the support plate to move vertically, which can adjust the height of the casting as needed.

[0006] Specifically, the sidewalls of the stop and the clamping block facing each other are fixed with a first anti-slip pad, and the sidewalls of the two clamping blocks facing each other are fixed with a second anti-slip pad.

[0007] By adopting the above technical solution, the setting of the first anti-slip pad and the second anti-slip pad not only improves the fixing effect, but also prevents the casting from being pinched and damaged.

[0008] Specifically, the limiting mechanism includes a sleeve, a locking bolt, and a limiting bolt. The sleeve has a vertical plate inside, and the side wall of the sleeve has two screw holes that are adapted to the locking bolts. The ends of the two locking bolts abut against the vertical plate. The vertical plate has two screw holes that are adapted to the limiting bolts. The ends of the two limiting bolts are fixed with limiting blocks, and the side walls of the two limiting blocks are fixed with third anti-slip pads.

[0009] By adopting the above technical solution, loosening the locking bolts, lifting the two vertical plates, and tightening the locking bolts, the height of the limiting block can be adjusted according to the thickness of the casting. The limiting bolts can be rotated until the third anti-slip pad is in close contact with the casting, thereby fixing castings of different thicknesses.

[0010] Specifically, two crossbars are fixed on the side of the clamping block away from the stop, and two through holes adapted to the crossbars are provided on the baffle plate.

[0011] By adopting the above technical solution, the crossbar configuration can improve the stability of the clamping block.

[0012] Specifically, the top of the base is fixed with four sleeves arranged in a rectangular array, each sleeve is provided with a vertical rod, and the top of each vertical rod is connected to a support plate.

[0013] By adopting the above technical solution, the installation of the sleeve and vertical rod can improve the stability of the support plate.

[0014] The beneficial effects of this utility model are:

[0015] (1) The casting clamping device described in this utility model places the casting on the top of the support plate, so that the casting is located between the clamping block and the stop.

The output shaft of the motor drives the bidirectional lead screw to rotate, and the two clamping blocks move towards each other. The two clamping blocks can clamp the casting from the other two sides. It can not only clamp castings of different lengths and widths, but also improve the fixing effect. The piston rod of the first hydraulic cylinder drives the support plate to move vertically, which can adjust the height of the casting as needed.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To improve the fixation effect, as one embodiment of this utility model, such as Figure 1 , Figure 2As shown, the present invention discloses a clamping device for casting processing, comprising a base 1, a first hydraulic cylinder 2 bolted to the top of the base 1, a support plate 3 bolted to the top of the piston rod of the first hydraulic cylinder 2, a baffle 6 and a stop seat 10 welded to the top of the support plate 3, a second hydraulic cylinder 7 bolted to the side of the baffle 6 away from the stop seat 10, a clamping block 9 bolted to the piston rod of the second hydraulic cylinder 7, and a motor 12 bolted to one side of the stop seat 10. The output shaft of the motor 12 is connected to a bidirectional lead screw 13 via a coupling. Two locking blocks 15 are provided above the support plate 3. Each locking block 15 has a screw hole adapted to the bidirectional lead screw 13. The stop seat 10 has two sliding grooves for the locking blocks 15 to slide on the side near the clamping block 9. Each sliding groove has a guide rod 14. Both guide rods 14 are welded to the stop seat 10. Each locking block 15 has a through hole adapted to the guide rod 14. The top of the clamping block 9 and the stop seat 10 are both welded to and fixed with a limit mechanism 11.

[0024] In use, the casting is placed on the top of the support plate 3, so that the casting is located between the clamping block 9 and the stop seat 10. The piston rod of the second hydraulic cylinder 7 drives the clamping block 9 to move towards the stop seat 10. The clamping block 9 and the stop seat 10 are in close contact with the casting, which can fix the casting from both sides. The output shaft of the motor 12 drives the double-acting screw 13 to rotate, and the two clamping blocks 15 move towards each other. The two clamping blocks 15 can clamp the casting from the other two sides of the casting. It can not only clamp castings of different lengths and widths, but also improve the fixing effect. The piston rod of the first hydraulic cylinder 2 drives the support plate 3 to move vertically, which can adjust the height of the casting as needed (the hydraulic cylinder is existing technology, and the specific structure and principle will not be described in detail).

[0025] To improve the clamping effect, the casting is protected, for example, such as... Figure 1 , Figure 2 As shown, the sidewalls of the stop 10 and the clamping block 9 facing each other are fixed with a first anti-slip pad 101 by adhesive, and the sidewalls of the two clamping blocks 15 facing each other are fixed with a second anti-slip pad 16 by adhesive.

[0026] To facilitate fixing castings of different thicknesses, for example, such as Figure 3 As shown, the limiting mechanism 11 includes a sleeve 17, a locking bolt 18, and a limiting bolt 20. The sleeve 17 has a vertical plate 19 inside. The side wall of the sleeve 17 has two screw holes that are adapted to the locking bolt 18. The ends of the two locking bolts 18 abut against the vertical plate 19. The vertical plate 19 has two screw holes that are adapted to the limiting bolt 20. The ends of the two limiting bolts 20 are welded and fixed with limiting blocks 21. The side walls of the two limiting blocks 21 are fixed with third anti-slip pads 22 by adhesive.

[0027] When in use, loosen the locking bolt 18, lift the two vertical plates 19, tighten the locking bolt 18, and adjust the height of the limiting block 21 according to the thickness of the casting. Rotate the limiting bolt 20 until the third anti-slip pad 22 is in close contact with the casting, thereby fixing castings of different thicknesses.

[0028] To improve the stability of clamping block 9, for example, such as Figure 1 As shown, two crossbars 8 are welded and fixed on the side of the clamping block 9 away from the stop 10, and the baffle 6 is provided with two through holes that are adapted to the crossbars 8.

[0029] To improve the stability of support plate 3, for example, such as Figure 1 As shown, four sleeves 4 arranged in a rectangular array are welded and fixed to the top of the base 1. Each sleeve 4 is provided with a vertical rod 5, and the top of each vertical rod 5 is welded to the support plate 3.

[0030] When this utility model is in use, the casting is placed on the top of the support plate 3, so that the casting is located between the clamping block 9 and the stop seat 10. The piston rod of the second hydraulic cylinder 7 drives the clamping block 9 to move towards the stop seat 10. The clamping block 9 and the first anti-slip pad 101 on the side wall of the stop seat 10 are in close contact with the casting, which can fix the casting from both sides.

[0031] Loosen the locking bolt 18, lift the two vertical plates 19, tighten the locking bolt 18, and adjust the height of the limiting block 21 according to the thickness of the casting. Rotate the limiting bolt 20 until the third anti-slip pad 22 is in close contact with the casting, thereby fixing castings of different thicknesses.

[0032] The output shaft of motor 12 drives the bidirectional lead screw 13 to rotate, and the two clamping blocks 15 move towards each other. The two clamping blocks 15 can clamp the casting from the other two sides of the casting, which can not only clamp castings of different lengths and widths, but also improve the fixing effect.

[0033] The piston rod of the first hydraulic cylinder 2 drives the support plate 3 to move vertically, which can adjust the height of the casting as needed (hydraulic cylinder is existing technology, and its specific structure and principle will not be described in detail).
