Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a flipping device for processing mechanical parts. Background Technology

[0002] As is well known, mechanical parts, also known as mechanical components, are the basic elements that constitute machinery. They are inseparable individual components that make up machinery and machines. In the production process of various automated machinery, mechanical parts need to be processed by cutting, welding, spraying, etc., and then the processed parts are assembled into finished products. When spraying mechanical parts, the parts are usually fixed on a fixture. However, because it is not convenient to flip the parts, paint drips when the workers spray the sides of the parts, which affects the spraying effect. Therefore, a flipping device for processing mechanical parts is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a flipping device for machining mechanical parts, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flipping device for machining mechanical parts, comprising: a worktable and a flipping mechanism;

[0005] The flipping mechanism includes a base and connecting plates symmetrically fixedly connected to one side of the workbench. A bracket is fixedly connected to the top of the base, and a forward and reverse motor is fixedly installed on the top of the bracket. A lead screw is fixedly connected to the output shaft of the forward and reverse motor. A vertical plate is symmetrically fixedly connected to the top of the base. A positioning block is movably connected inside the vertical plate. An internally threaded cylinder is fixedly connected to one side of the positioning block. The inner wall of the internally threaded cylinder is threadedly connected to the lead screw. The interior of the connecting plate is rotatably connected to the vertical plate through a rotating shaft. A first slot and a second slot for inserting the positioning block are respectively opened on both sides of the connecting plate.

[0006] By adopting the above technical solution, after the parts are fixed on the worktable, they can be sprayed first. When the parts need to be flipped, the forward and reverse motor can drive the lead screw to rotate clockwise, so that the positioning block can move inside the vertical plate under the action of the internal threaded cylinder, and then the positioning block can be moved out of the second groove. At this time, the connecting plate loses the fixing force. When the worktable is flipped 90 degrees, the forward and reverse motor can drive the lead screw to rotate counterclockwise, so that the positioning block can be inserted into the first groove to position the flipped connecting plate. Thus, the side of the parts fixed on the worktable can face upward, which makes it easier for the workers to carry out uniform and effective spraying work on the parts.

[0007] Preferably, the interior of the upright plate has a slot, and a rod is fixedly embedded inside the slot. The interior of the positioning block is slidably connected to the rod.

[0008] By adopting the above technical solution, the positioning block can move smoothly in a straight line under the action of the internal threaded cylinder and the lead screw.

[0009] Preferably, a controller is fixedly installed on the outside of the bracket, and the electrical control output terminal of the controller is electrically connected to the electrical control input terminal of the forward and reverse motor through a wire.

[0010] By adopting the above technical solution, it is easy to control the operating status of the forward and reverse motor.

[0011] Preferably, a weight is fixedly connected to the bottom of the base.

[0012] By adopting the above technical solution, the base can be stably placed on a horizontal surface for use.

[0013] Preferably, the outer side of the weight is uniformly fixedly connected with protrusions, and the inner thread of the protrusions is connected with a third bolt.

[0014] By adopting the above technical solution, the protrusion can be fixed after the third bolt is screwed into the reserved threaded groove on the processing equipment, thereby making it easier for the device to remain stable during use.

[0015] Preferably, there are two connecting plates, one of which has a handle fixedly connected to its outer side.

[0016] By adopting the above technical solution, it is easy to flip the worktable.

[0017] Preferably, a connecting block is detachably connected to the outer side of the workbench, and a second bolt is threadedly connected to the inside of the connecting block. One end of the second bolt is rotatably connected to a clamping plate via a bearing, and one side of the clamping plate is slidably connected to the inside of the connecting block via a sliding plate.

[0018] By adopting the above technical solution, when the part is placed between the two clamping plates, the clamping plates can be driven to clamp the part by tightening the second bolt.

[0019] Preferably, a fixing plate is fixedly connected to one side of the connecting block, and the interior of the fixing plate is threadedly connected to a threaded hole by a first bolt.

[0020] By adopting the above technical solution, it is convenient for staff to position and adjust the connecting block according to actual needs.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The flipping device for machining these mechanical parts uses a flipping mechanism on the worktable to enable the forward and reverse motors to drive the positioning block to move via a lead screw and an internal threaded cylinder. This allows the worktable to be flipped and positioned according to actual needs, allowing workers to flexibly adjust the position of the parts during spraying operations. This avoids the problem of paint dripping and affecting the spraying effect when spraying the sides of the parts. Attached Figure Description

This allows the positioning block 25 to move out of the second groove, at which point the connecting plate 27 loses its fixing force. When the worktable 1 is flipped 90 degrees, the reversible motor 22 drives the lead screw 23 to rotate counterclockwise, allowing the positioning block 25 to be inserted into the first groove to position the flipped connecting plate 27. This ensures that the side of the parts fixed on the worktable 1 faces upwards, facilitating even and effective painting by the operator. The flipping mechanism 2 includes a base 20 and a connecting plate 27 symmetrically fixedly connected to one side of the workbench 1. A bracket 21 is fixedly connected to the top of the base 20.

[0038] Secondly, in order to enable the positioning block 25 to move smoothly in a straight line under the action of the internal threaded cylinder 24 and the lead screw 23, a slot 202 is provided inside the vertical plate 26, and a rod 203 is fixedly embedded inside the slot 202. The inside of the positioning block 25 is slidably connected to the rod 203. In order to facilitate the control of the operation of the forward and reverse motor 22, a controller 208 is fixedly installed on the outside of the bracket 21.

[0039] Furthermore, to ensure the base 20 is stably placed on a horizontal surface, a weight 204, made of cast iron, is fixedly connected to the bottom of the base 20. To secure the protrusion 206 after the third bolt 207 is screwed into the pre-drilled threaded groove on the processing equipment, thus facilitating stability during use, protrusions 206 are evenly fixedly connected to the outer side of the weight 204, and the third bolt 207 is threadedly connected to the inside of the protrusion 206.

When the worktable 1 is flipped 90 degrees, the forward and reverse motor 22 can drive the lead screw 23 to rotate counterclockwise, so that the positioning block 25 can be inserted into the first groove to position the flipped connecting plate 27. Thus, the side of the part fixed on the worktable 1 can face upward, which makes it easier for the operator to carry out uniform and effective spraying work on the part.
