Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piston ring production equipment, and more specifically to a clamp for sand dropping during piston ring casting. Background Art
[0002] Piston rings are important components of locomotive engines. They play the role of sealing, controlling lubricating oil, dissipating heat, and supporting and guiding in the engine. When piston rings are mass-produced, the mold is usually filled with green sand and molten iron is poured into the sand mold. After the casting is cooled and solidified, the sand mold is stacked on a transport cart and transported along the starting end of the molding line to the sand dropout point at the other end of the molding line. Finally, the stacked sand molds are manually transported one by one into the sand dropout equipment to remove the sand attached to the surface of the casting.
[0003] The current industry lacks a special fixture for transferring sand molds from a transport cart to a sand drop device. A single sand mold weighs nearly 12 kilograms. During the transfer of the sand mold, workers' wrist joints and lumbar vertebrae are subjected to greater stress, which can easily lead to diseases such as wrist joint injuries and limited lumbar spine movement. The traditional transportation method is not only inefficient, but also extremely labor-intensive for workers. Therefore, it is urgent to study a fixture for transferring piston ring sand molds to solve the above industry problems. Utility Model Content
[0004] 1. Technical issues to be solved
[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a clamp for sand dropping in piston ring casting, which can realize the clamping and transportation operations of the piston ring sand mold through semi-automatic control, and can lift and transport a pile of piston ring sand molds together in a very short time, thereby effectively reducing the labor intensity of workers and preventing related occupational diseases caused by long-term handling work. The utility model is easy to operate and can be quickly used after simple training, so it is suitable for large-scale promotion.
[0006] 2. Technical solution
[0007] To solve the above problems, the utility model adopts the following technical solutions.
[0008] The cam is connected with the piston ring through the support frame, and the support frame is connected with the support frame by the support frame, and the support frame is connected with the support frame by the support frame. The cam is provided with a through hole, and one end of the driven clamping plate away from the positioning clamping plate is fixedly connected with a connecting disk, and one end of the driven push rod away from the electric push rod passes through the slide groove and the through hole and is fixedly connected to the connecting disk; a control switch and a low-voltage control power supply are installed on the side wall of the positioning clamping plate, and the ends of the positioning clamping plate and the driven clamping plate close to each other are fixedly connected with load-bearing hooks, and the left and right ends of the piston ring sand mold are fixedly connected with positioning hanging handles, and the load-bearing hooks are hoisted with the positioning hanging handles, so that the piston ring sand mold can be clamped and transported through semi-automatic control, and a pile of piston ring sand molds can be hoisted and transported together in a very short time, which effectively reduces the labor intensity of workers and prevents related occupational diseases caused by long-term handling work. The operation is simple and can be quickly mastered after simple training, which is suitable for large-scale promotion.
[0009] Furthermore, the control switch is electrically connected to the electric push rod, and the control switch is provided with an operating button for controlling the opening and closing and forward and reverse rotation of the electric push rod. When hoisting the piston ring sand mold, the electric push rod is first controlled by the control switch to extend its power output end, driving the driven push rod, the connecting disk and the driven clamping plate to move toward the end away from the positioning clamping plate, so that the distance between the pair of load-bearing hooks is greater than the distance between the pair of positioning hanging handles, and then the clamp is controlled to move downward by the transport sling until the pair of load-bearing hooks are located on both sides of the lower end of the positioning hanging handle, and the power output end of the electric push rod is shortened again by the control switch, so that the driven push rod drives the connecting disk and the driven clamping plate to reset, and the load-bearing hook is located directly below the positioning hanging handle at the moment, and finally the transport sling is controlled to raise the clamp, thereby completing the hoisting.
[0010] Furthermore, the connecting disk is welded on the side wall of the driven clamping plate, and the connecting disk covers the through hole, which can ensure that the electric push rod drives the driven push rod to drive the connecting disk and the driven clamping plate to move synchronously during the movement.
[0011] Furthermore, the load-bearing hooks are arranged in a pair, and the number of the positioning handles on each piston ring sand mold matches the load-bearing hooks. When a plurality of the piston ring sand molds are stacked in a stack, the positioning handle on the piston ring sand mold located at the bottom always corresponds to the position of the load-bearing hook. The load-bearing hook and the positioning handle on the piston ring sand mold located at the bottom can lift the stack of piston ring sand molds synchronously. When placing the molds, personnel only need to place the positioning handle on the piston ring sand mold located at the bottom in a position suitable for lifting by the load-bearing hook, thereby reducing the labor intensity of personnel in the previous process, and there is no need to align the positioning handles on the piston ring sand molds one by one.
[0012] 3. Beneficial effects

[0015] (2) The load-bearing hooks are arranged in a pair, and the number of the positioning handles on each piston ring sand mold matches the number of the load-bearing hooks. When multiple piston ring sand molds are stacked, the positioning handle on the piston ring sand mold at the bottom always corresponds to the position of the load-bearing hook. The stack of piston ring sand molds can be lifted synchronously by lifting the load-bearing hook and the positioning handle on the piston ring sand mold at the bottom. When placing the molds, the personnel only need to place the positioning handle on the piston ring sand mold at the bottom at a position suitable for lifting by the load-bearing hook, thereby reducing the labor intensity of the personnel in the previous process, and there is no need to align the positioning handles on the piston ring sand molds one by one.

[0025] Embodiment 1:
[0026] See also Figure 1-4A fixture for sand dropping of piston ring casting comprises a fixture 1 and a piston ring sand mold 9. The fixture 1 is used to clamp the piston ring sand mold 9 and transport it to the location of the sand dropping equipment. The fixture 1 is composed of a positioning clamping plate 101 and a driven clamping plate 102. A positioning tube 2 is fixedly connected to the inner wall of the positioning clamping plate 101 close to one end of the driven clamping plate 102. The positioning tube 2 is not directly fixedly connected to the driven clamping plate 102. A lifting hook 3 is fixedly connected to the top of the positioning tube 2. The other end of the lifting hook 3 is connected to an external transport hanger. The transport hanger controls the lifting and movement of the fixture 1 through the lifting hook 3. An assembly cavity 201 is opened in the positioning tube 2. An electric push rod 4 and a driven push rod 5 are installed in the assembly cavity 201. The power output end of the electric push rod 4 is connected to the driven push rod 5. The active push rod 5 is fixedly connected, and a slide groove 202 connected to the assembly cavity 201 is provided on one side wall of the positioning tube 2 close to the driven clamping plate 102, and a through hole matching the specification of the slide groove 202 is provided on the side wall of the driven clamping plate 102. The driven clamping plate 102 is fixedly connected with a connecting disk 6 at one end away from the positioning clamping plate 101, and the end of the driven push rod 5 away from the electric push rod 4 passes through the slide groove 202 and the through hole and is fixedly connected to the connecting disk 6. A control switch 7 and a low-voltage control power supply are installed on the side wall of the positioning clamping plate 101, and the ends of the positioning clamping plate 101 and the driven clamping plate 102 close to each other are fixedly connected with a load-bearing hook 8, and the left and right ends of the piston ring sand mold 9 are fixedly connected with a positioning hanging handle 901, and the load-bearing hook 8 is hoisted with the positioning hanging handle 901.
[0027] The control switch 7 is electrically connected to the electric push rod 4. The control switch 7 is provided with an operating button for controlling the opening and closing and the forward and reverse rotation of the electric push rod 4. The transport hoist is controlled by an external drive device which is not shown in this figure. It is worth noting that the installation and electrical connection method of the control switch 7 and the electric push rod 4, as well as the installation and installation and electrical connection method of the transport hoist and the external drive device are conventional electrical technologies and will not be described in detail here. When the piston ring sand mold 9 is hoisted, the electric push rod 4 is first controlled by the control switch 7 to extend its power output end, driving the driven push rod 5, the connecting plate 6 and the driven clamping plate 102 to move away. Move away from one end of the positioning clamping plate 101, so that the distance between the pair of load-bearing hooks 8 is greater than the distance between the pair of positioning handles 901, and then control the clamp 1 to move downward through the transport sling until the pair of load-bearing hooks 8 are located on both sides of the lower end of the positioning handle 901, and again control the power output end of the electric push rod 4 to shorten through the control switch 7, so that the driven push rod 5 drives the connecting disk 6 and the driven clamping plate 102 to reset. At this time, the load-bearing hook 8 is located directly below the positioning handle 901, and finally control the transport sling to make the clamp 1 rise, so that the load-bearing hook 8 is stuck in the positioning handle 901, and the lifting is completed.
[0028] The connecting plate 6 is welded to the side wall of the driven clamping plate 102, and the connecting plate 6 covers the through hole, which can ensure that the electric push rod 4 drives the driven push rod 5 to drive the connecting plate 6 and the driven clamping plate 102 to move synchronously during the movement.
[0029] The load-bearing hooks 8 are arranged in a pair, and the number of the positioning handles 901 on each piston ring sand mold 9 matches the load-bearing hooks 8. When multiple piston ring sand molds 9 are stacked in a stack, the positioning handle 901 on the piston ring sand mold 9 at the bottom always corresponds to the position of the load-bearing hook 8. The load-bearing hook 8 and the positioning handle 901 on the piston ring sand mold 9 at the bottom can lift the stack of piston ring sand molds 9 synchronously. When placing, the personnel only need to place the positioning handle 901 on the piston ring sand mold 9 at a position suitable for the lifting of the load-bearing hook 8, thereby reducing the labor intensity of the personnel in the previous process, and there is no need to align the positioning handles 901 on the piston ring sand mold 9 one by one.
[0030] Working principle: When the operator uses the clamp to transport the stacked piston ring sand molds 9 to the location of the sand falling equipment, the operator first controls the electric push rod 4 through the control switch 7 to extend its power output end, driving the driven push rod 5, the connecting disk 6 and the driven clamping plate 102 to move toward the end away from the positioning clamping plate 101, so that the distance between the pair of load-bearing hooks 8 is greater than the distance between the pair of positioning hangers 901, and then controls the lifting hook 3 through the transport sling to drive the clamp 1 to move downward until the pair of load-bearing hooks 8 are located on both sides of the lower end of the positioning hanger 901, and controls the power output end of the electric push rod 4 to shorten again through the control switch 7, so that the driven push rod 5 drives the connecting disk 6 and the driven clamping plate 102 to move toward the end away from the positioning clamping plate 101. The movable clamping plate 102 is reset, and the load-bearing hook 8 is now located just below the positioning handle 901. Finally, the transport sling is controlled to raise the clamp 1 so that the load-bearing hook 8 is stuck in the positioning handle 901. At this point, the lifting is completed, and finally the clamp 1 is transported to the location of the sand falling equipment through the transport sling. Compared with the prior art, the utility model can realize the clamping and transportation operations of the piston ring sand mold through semi-automatic control, and can lift and transport a pile of piston ring sand molds together in a very short time, effectively reducing the labor intensity of workers and preventing related occupational diseases caused by long-term handling work. It is easy to operate and can be quickly used after simple training, so it is suitable for large-scale promotion.
[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
