Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a clamping and conveying equipment for metal casting processing. Background Art

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed, so it can achieve the purpose of no mechanical processing or a small amount of processing, which reduces costs and reduces time to a certain extent. Casting is one of the basic processes in the modern machinery manufacturing industry.

[0003] Currently, in the process of conveying metal castings, the castings are clamped by clamps, and the conveying mechanism drives the clamps to slide along the guide rails to convey them to the specified position. Since the size of traditional clamps is fixed, they can only clamp castings of a single size. For long strips or rods, the clamping is unstable, the scope of use is limited, and the scope of application is narrow. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a clamping and conveying device for metal casting processing. By connecting a pair of clamps to a flip frame, the two clamps can be used separately or in combination, thereby overcoming the shortcomings of the prior art clamp mechanism with limited use range, and aims to solve the problems in the background technology.

[0005] In order to achieve the above technical objectives, the specific technical scheme of the present invention is as follows: a clamping and conveying device for metal casting processing proposed by the present invention includes: a slide rail; a chassis sliding along the slide rail, and a lifting mechanism is connected to the chassis; a clamping mechanism is connected to the lifting mechanism; the clamping mechanism includes a connecting frame, the connecting frame is fixedly connected to the lifting mechanism, a first rotating motor is installed on the connecting frame, and a rotating frame is fixedly connected to the rotating shaft of the first rotating motor; a second rotating motor is installed on the rotating frame, and a rotating arm is fixedly connected to the rotating shaft of the second rotating motor, and one end of the rotating arm is connected to a clamping assembly; the clamping assembly includes a flip frame, and a pair of rotatable clamp seats are symmetrically connected at both ends of the flip frame, and a clamp is installed on the clamp seat.

[0006] As a preferred technical solution of the present invention, the center of the flip frame is rotatably connected to a rotating seat, the rotating seat is fixedly connected to a hinge frame, and the hinge frame is hinged to one end of the rotating arm.

[0007] As a preferred technical solution of the present invention, a pair of reciprocating components are installed on the flip frame to drive the clamp seat to rotate, and the reciprocating components include: an L-shaped bracket, the bracket is fixedly connected to the flip frame, the bracket is rotatably connected to a rotating cylinder, the surface of the rotating cylinder is provided with a pair of spiral grooves in opposite directions, and the bracket is slidably connected to a slider, the slider is connected to an arc block slidably connected to the spiral groove, and when the rotating cylinder rotates, the arc block is driven to slide back and forth in the two spiral grooves.

[0008] As a preferred technical solution of the present invention, a support plate is fixedly connected to the clamp seat, a connecting rod is rotatably connected between the support plate and the slider, and a guide hole slidably connected to the slider is provided on the bracket.

[0009] As a preferred technical solution of the present invention, the rotating seat is fixedly connected with a bevel gear ring, and a bevel gear meshing with the bevel gear ring is coaxially fixedly connected to the rotating cylinder. When the flip frame rotates on the rotating seat, the rotating cylinder rotates, which in turn drives the slider to slide on the bracket. When the slider slides, it drives the clamp seat to rotate.

[0010] As a preferred technical solution of the present invention, an outer gear ring is fixedly connected to the surface of the flip frame, and a third rotating motor is installed on the hinge frame, and a driving gear meshing with the outer gear ring is fixedly connected to the rotating shaft of the third rotating motor.

[0012] As a preferred technical solution of the present invention, the clamp includes a clamping cylinder and two clamping jaws, and the clamping cylinder is used to drive the two clamping jaws to move.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention connects a pair of clamp seats at both ends of the flip frame, and the clamp seats are fixedly connected with clamps. The sizes of the two clamps can be changed. The two clamps can be switched by flipping the flip frame 180 degrees, thereby clamping castings of different shapes and sizes.

[0015] 2. The present invention connects a reciprocating assembly to the turning frame. When the turning frame rotates 90° and turns from a vertical state to a horizontal state, the two clamps can be driven to rotate to a state perpendicular to the turning frame. The turning frame is then driven by a turning motor to rotate the clamps downward, so that the two clamps can be used in combination to clamp and transport long strips or rod-shaped castings.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment: This embodiment discloses a clamping and conveying device for metal casting processing, such as Figure 1-Figure 6 As shown, it includes: a slide rail 1, which can be fixedly installed on the top of a factory building; a chassis 2 that slides along the slide rail 1, and a motor assembly is provided in the chassis 2, which can drive the chassis 2 to automatically slide along the slide rail 1, and a lifting mechanism 21 is connected to the chassis 2, and the lifting mechanism 21 adopts a cylinder; a clamping mechanism 3, which is connected to the lifting mechanism 21, and the casting is clamped by the clamping mechanism 3 and transported to a specified position along the slide rail 1.

[0025] like Figure 2-Figure 3As shown, the clamping mechanism 3 includes a connecting frame 31, which is fixedly connected to the lifting mechanism 21 by a bolt assembly. A first rotating motor 32 is installed on the upper surface of the connecting frame 31, and a rotating frame 33 is fixedly connected to the rotating shaft of the first rotating motor 32. The first rotating motor 32 can drive the rotating frame 33 to rotate horizontally; a second rotating motor 34 is installed on the rotating frame 33, and a rotating arm 35 is fixedly connected to the rotating shaft of the second rotating motor 34. The rotating arm 35 is horizontally arranged, and one end of the rotating arm 35 is connected to the clamping assembly 4.

[0026] like Figure 3-Figure 5 As shown, the clamping assembly 4 includes a flip frame 41, and a pair of rotatable clamp seats 410 are symmetrically connected at both ends of the flip frame 41. A clamp 49 is installed on the clamp seat 410. The clamp 49 can be removed and replaced on the clamp seat 410. The two clamps 49 can be the same or different in size; the flip frame 41 is centrally rotatably connected to a rotating seat 44, and a hinge frame 43 is fixedly connected to the rotating seat 44. The hinge frame 43 is hinged to one end of the rotating arm 35; a driven gear 48 is coaxially fixedly connected to the hinge frame 43, and a flip motor is installed on the rotating arm 35. 36, the flip motor 36 has an automatic locking function. A driving gear 37 meshing with a driven gear 48 is fixedly connected to the rotating shaft of the flip motor 36; the driving gear 37 is driven to rotate by the flip motor 36, and the driven gear 48 and then the hinge frame 43 are driven to rotate, and then the flip frame 41 is driven to flip from a vertical state to a horizontal state; and the rotating arm 35 is driven to rotate 180° by the second rotating motor 34, and then the flip frame 41 is driven to rotate 180°, and the positions of the two clamps 49 are switched, so as to clamp castings of different sizes.

[0027] Preferably, the clamp 49 includes a clamping cylinder and two clamping jaws. The clamping cylinder is used to drive the two clamping jaws to move. The specific movement principle is the existing technology and will not be described in detail here.

[0028] Preferably, an outer gear ring 45 is fixedly connected to the surface of the flip frame 41, and the outer gear ring 45 is arranged on the back side of the flip frame 41 and centered on the rotating seat 44, and a third rotating motor 46 is installed on the hinge frame 43, and the third rotating motor 46 has a locking function. A driving gear 47 meshing with the outer gear ring 45 is fixedly connected to the rotating shaft of the third rotating motor 46; the driving gear 47 is driven to rotate by the third rotating motor 46, thereby driving the flip frame 41 to rotate around the rotating seat 44 as the center.

[0029] like Figure 4 and Figure 6As shown, a pair of reciprocating components 42 are installed on the flip frame 41, which are used to drive the clamp seat 410 to rotate. The reciprocating component 42 includes: an L-shaped bracket 422, the bracket 422 is fixedly connected to the flip frame 41, and a rotating cylinder 421 is rotatably connected to the bracket 422. A pair of spiral grooves 424 in opposite directions are provided on the surface of the rotating cylinder 421, and a slider 425 is slidably connected to the bracket 422. A guide hole slidably connected to the slider 425 is provided on the bracket 422; an arc block 426 slidably connected to the spiral groove 424 is connected to the slider 425, and when the rotating cylinder 421 rotates, the arc block 426 is driven to slide back and forth in the two spiral grooves 424, thereby driving the slider 425 to slide back and forth on the bracket 422; wherein, a support plate 413 is fixedly connected to the clamp seat 410, and a connecting rod 411 is rotatably connected between the support plate 413 and the slider 425 The rotating seat 44 is fixedly connected to the bevel gear ring 412, and the rotating cylinder 421 is coaxially fixedly connected to the bevel gear ring 412. When the turning frame 41 rotates on the rotating seat 44, the rotating cylinder 421 is driven to rotate, thereby driving the slider 425 to slide on the bracket 422, and the slider 425 drives the clamp seat 410 to rotate when it slides; wherein, when the turning frame 41 rotates 90°, from a vertical state to a horizontal state, the rotating cylinder 421 rotates to drive the slider 425 to slide from one end of the bracket 422 to the other end, thereby driving the clamp 49 to rotate 90°, so that the two clamps 49 and the turning frame 41 are both kept in a vertical state; similarly, when the turning frame 41 rotates from a horizontal state to a vertical state again, it will drive the slider 425 to move back to the original end position, thereby making the two clamps 49 remain parallel to the turning frame 41 again.

[0030] Working principle: The present invention drives the rotating arm 35 to rotate through the second rotating motor 34, and drives the flip frame 41 to rotate 180°, which can drive the two clamps 49 to exchange positions with each other, switch the clamps 49, and then clamp and convey castings of different sizes; and the third rotating motor 46 can drive the flip frame 41 to rotate 90° with the rotating seat 44 as the center, so that the flip frame 41 rotates from a vertical state to a horizontal state. During the rotation of the flip frame 41, the rotating cylinder 421 is driven to rotate, and then the slider 425 is driven to slide from one end of the bracket 422 to the other end, and then the clamp 49 is driven to rotate 90°, so that the two clamps 49 are both in a state perpendicular to the flip frame 41, and then the flip motor 36 drives the flip frame 41 to rotate 90°, so that the flip frame 41 faces downward, that is, the two clamps 49 are both in a downward state. At this time, through the cooperation of the two clamps 49, the long strip, tubular, and rod-shaped castings can be clamped and fixed, thereby increasing the function of the clamping mechanism 3 and improving the scope of use.
