Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and more specifically, to a special gripper for clutch hub parts. Background Technology

[0002] As auto parts manufacturers continue to advance unmanned production technologies, more and more operations are being performed using various types of robots, including the picking and handling of parts. For example... Figure 5 The image shows a clutch hub part produced in large quantities by a company. The part is characterized by a very smooth outer wall in the small diameter section and a toothed outer wall in the large diameter section. This makes it difficult for the robot to grasp the part. If it grasps the outer wall in the small diameter section, the part is easy to slip off. If it grasps the outer wall in the large diameter section, the toothed surface is easy to be damaged. Therefore, the company needs to design a special gripper to meet the grasping requirements of this type of part. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a special gripper for clutch hub parts. This utility model is connected to the clutch hub parts by insertion. This utility model is designed with an airbag installed. The airbag is inflated to drive the finger plate on the gripping finger element to extend outward. After the finger plate extends outward, it can lift and grasp the clutch hub parts. This utility model can effectively solve the problems of parts slipping and parts damage, and can meet the needs of production and use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A special gripper for clutch hub parts includes a cylinder and a chassis. The cylinder is vertically continuous, and the chassis is fixedly connected to the bottom of the cylinder. A cavity is formed in the center of the chassis, and an air bladder is installed in the cavity. Several gripping finger elements are installed on the lower surface of the chassis. The gripping finger elements are evenly distributed circumferentially with the center of the chassis as the center. The gripping finger elements are all connected to the air bladder. Each gripping finger element includes a telescopically movable finger plate, which can be driven by the air bladder to extend outward to the outer edge of the chassis.

[0006] Furthermore, the top of the bladder cavity is open, and a cavity cover is installed at the open position of the top of the bladder cavity, forming a closed airbag storage space.

[0007] Furthermore, the finger grasping element also includes a finger box, a piston, and a spring. The finger box is fixedly installed on the lower surface of the chassis. A horizontally arranged piston hole is opened in the finger box. The piston is fitted into the piston hole. One end of the piston is connected to a finger plate, and the other end is connected to a drive rod. The spring is installed in the piston hole and is fitted on the outside of the finger plate. One end of the drive rod passes through the finger box and extends into the sac cavity.

[0008] Furthermore, the spring force can cause the finger plate to retract, and the retraction of the finger plate ensures that the outer end of the finger plate does not exceed the outer edge of the chassis.

[0009] Furthermore, the cavity cover is equipped with an air inlet and an air outlet, both of which are connected to an airbag. An airbag control element is installed inside the cylinder, comprising a bracket and a solenoid valve. The bracket is fixedly connected to the inner wall of the cylinder, and the solenoid valve is mounted on the bracket. The air inlet pipe is connected to the air outlet port of the solenoid valve, and the air outlet pipe is connected to the air release port of the solenoid valve.

[0010] Furthermore, a flange is connected to the top of the cylinder.

[0011] Furthermore, the outer side of the cylinder is fitted with a collision protection sleeve, which is made of rubber material and has an outer diameter equal to that of the chassis.

[0012] Furthermore, a status indicator light is installed on the outer wall of the cylinder, and the status indicator light displays different colors according to the status of the airbag.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 The image shows a special gripper for clutch hub parts, used for such... Figure 5 The illustration shows a gripping operation for a clutch hub part. The gripper includes a cylinder 1 and a chassis 2. The cylinder 1 is vertically continuous, and a flange 11 is connected to the top of the cylinder 1, allowing the gripper to be connected to the end of the robotic arm of a gripping robot. The chassis 2 is fixedly connected to the bottom of the cylinder 1. Figure 5The clutch hub part shown is characterized by a through hole in the center. The gripper design of this invention utilizes this through hole to determine the position of the chassis 2, which is the position of the gripper's maximum diameter. The outer diameter of the chassis 2 is designed to be slightly smaller than the inner diameter of the central through hole in the clutch hub part (just slightly smaller to facilitate gripper insertion). A cavity 21 is formed in the center of the chassis 2, into which an air bladder 23 is installed. The air bladder 23 can be inflated and deflated. Several gripping finger elements 3 are mounted on the lower surface of the chassis 2, evenly distributed circumferentially around the center of the chassis 2. All gripping finger elements 3 are connected to the air bladder 23 via a transmission connection. Each gripping finger element 3 includes a telescopically movable finger plate 31. When the air bladder 23 is deflated and contracted, all the finger plates 31 of the gripping finger elements 3 are in a retracted state. At this time, the position of the gripper's maximum diameter is the chassis 2, thus allowing insertion through the through hole. The airbag 23 is inflated inside the clutch hub component. The inflated airbag 23 expands and drives the finger plate 31 to extend outwards to the outer edge of the chassis 2. The maximum diameter formed by the extension of all the finger plates 31 will be greater than the diameter of the through hole in the clutch hub component. At this point, the gripper cannot be pulled upwards. Lifting the gripper upwards allows the finger plate 31 to lift and pick up the clutch hub component, thus achieving gripping of the clutch hub component. To separate the gripper from the clutch hub component, simply retract the finger plate 31. This invention differs from traditional gripper designs that clamp the outer wall of components. The lifting and gripping design of this invention is more scientific, satisfying the gripping needs without damaging the outer surface of the component and solving the problem of component slippage. This invention effectively meets the gripping requirements of the clutch hub component. To improve gripping stability and distribute force, the number of gripping finger elements 3 in this invention is no less than six.

[0023] like Figure 2 As shown, the top of the bladder cavity 21 is open to facilitate the insertion of the airbag 23. The top opening of the bladder cavity 21 is covered by a cavity cover 22. After the cavity cover 22 is installed, a closed storage space for the airbag 23 is formed inside the bladder cavity 21. The expansion direction and expansion size of the airbag 23 are determined. This design is to cooperate with the drive of all the gripping finger elements 3.

[0024] like Figure 2 and Figure 3As shown, the finger gripping element 3 also includes a finger box 32, a piston 33, and a spring 34. The finger box 32 is fixedly installed on the lower surface of the chassis 2. A horizontally arranged piston hole 321 is opened in the finger box 32. The piston 33 is fitted into the piston hole 321. One end of the piston 33 is connected to the finger plate 31, and the other end is connected to the drive rod 35. The piston 33 guides the movement of the finger plate 31 and the drive rod 35, allowing the finger plate 31 and the drive rod 35 to move laterally. The spring 34 is installed in the piston hole 321 and is fitted onto the outside of the finger plate 31. Figure 3 As shown, under the force of spring 34 alone, piston hole 321 is pushed to the right. At this time, finger plate 31 retracts and drive rod 35 extends outward. This situation occurs after airbag 23 is deflated. One end of drive rod 35 passes through finger box 32 and extends into bladder cavity 21. After airbag 23 is deflated, airbag 23 will retract as a whole. The movement of drive rod 35 into bladder cavity 21 is unrestricted. If finger plate 31 is to extend, airbag 23 only needs to be inflated. After airbag 23 is inflated, it swells and pushes drive rod 35 to move outward towards the outside of chassis 2 by air pressure. At this time, spring 34 is compressed and finger plate 31 will extend outward. In order to achieve the effect of lifting and grabbing parts, finger plate 31 will extend beyond the outer edge of chassis 2. In order to make the gripper easy to install, the retraction of finger plate 31 will prevent the outer end of finger plate 31 from exceeding the outer edge of chassis 2.

[0025] like Figure 2As shown, this utility model has an air inlet 221 and an exhaust outlet 222 installed on the cavity cover 22. Both the air inlet 221 and the exhaust outlet 222 are connected to the airbag 23. An airbag control element 4 is installed inside the cylinder 1. The airbag control element 4 includes a bracket 41 and a solenoid valve 42. The bracket 41 is fixedly connected to the inner wall of the cylinder 1. The solenoid valve 42 is installed on the bracket 41. The solenoid valve 42 is a three-position three-way solenoid valve. The solenoid valve 42 has an air inlet port, an air outlet port, and an exhaust port. The air port has three positions: one for air intake, one for pressure holding, and one for air release. The three-way valve indicates that air intake, pressure holding, and air release are all connected. The air intake port 221 is connected to the air outlet port of the solenoid valve 42. After the solenoid valve 42 switches to the air intake position, the airbag 23 is inflated through the air intake port 221. The air intake volume needs to ensure that the airbag 23 expands to the set size. After the airbag 23 has fully expanded, all the finger plates 31 of the gripping elements 3 have extended outwards. At this time, the solenoid valve 42... 2. Switch to the pressure holding position for pressure holding. During pressure holding, no gas escapes from the airbag 23, maintaining the extended state of the finger plate 31. When it is necessary to remove the gripper, the solenoid valve 42 switches to the venting position. The vent pipe 222 is connected to the venting port of the solenoid valve 42. The gas in the airbag 23 is released through the vent pipe 222, causing the airbag 23 to contract and the finger plate 31 to contract elastically. In this utility model, the solenoid valve 42 can be powered by the existing wiring of the gripping robot, and the gas in the airbag 23 can also be connected to the existing air pipeline of the gripping robot. In this utility model, a status indicator light 13 is installed on the outer wall of the cylinder 1. The status indicator light 13 displays different colors according to the status of the airbag 23. In this company, it is set that the airbag 23 is in the deflated state and the airbag 23 is in the inflated state and the green light is displayed to distinguish them. When the red light is on, the gripper can be inserted or removed. When the green light is on, the parts can be gripped and moved.

[0026] Because the central through hole of the clutch hub component is a toothed hole, when this gripper is inserted or removed, or even during the handling of the component, it may encounter the toothed wall. Therefore, if... Figure 2 As shown, this utility model designs and installs an anti-collision protective sleeve 12 on the outside of the cylinder 1. The anti-collision protective sleeve 12 is made of rubber material, and the outer diameter of the anti-collision protective sleeve 12 is equal to the outer diameter of the chassis 2. This utility model also needs to coat the outer edge of the chassis 2 with a rubber protective layer to prevent damage to the tooth wall.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
