Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and in particular relates to a switch assembly turntable clamp. Background Technology

[0002] When push-button switches are assembled automatically via a multi-station turntable, existing switch housing clamps use electric push rods to control the opening and closing of their clamping blocks for clamping, fixing, and unloading the switch housings. Since the switch housing clamps rotate in the same direction as the turntable, the electric push rods are powered via a ring-shaped brush contact. In long-term production use, the ring-shaped brushes need to be replaced and maintained. Furthermore, the electric push rods also suffer from large space occupancy and high operating costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a switch assembly turntable clamp with a non-circuit mechanical structure to solve the problems of high cost and maintenance required for electric push rods.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a switch assembly turntable fixture, comprising a lower fixed plate, an upper turntable and tooling fixtures, wherein the upper turntable is rotatably mounted on the lower fixed plate, and several tooling fixtures are fixedly arranged in a circular array on the upper turntable;

[0005] The tooling fixture consists of a base, a fixed clamping block, a movable clamping block, guide rods, springs, drive rods, and guide columns. The base is fixedly mounted on the upper turntable, and a connecting plate is fixedly mounted on the outer end of the base. The base has a groove in the middle, and the fixed clamping block is fixedly mounted in the groove of the base. The movable clamping block is slidably mounted in the groove of the base. Two guide rods and one drive rod are slidably mounted in the connecting plate. The inner ends of the guide rods and drive rods are fixedly connected to the movable clamping block. The spring is sleeved on the guide rod, and the inner and outer ends of the spring act on the movable clamping block and the connecting plate, respectively. Two guide columns are fixedly mounted on two adjacent tooling fixture positions on the upper turntable, respectively. An inclined guide groove is provided on the bottom surface of the drive rod.

[0006] Preferably, a pad is screwed and fixedly installed on the lower fixed plate, and the guide post is fixedly installed on the top of the pad.

[0007] Preferably, the clamping surfaces of the fixed clamping block and the movable clamping block are provided with an arc groove structure.

[0008] Preferably, the inlet and outlet of the inclined guide groove are both designed with rounded corners.

[0009] Compared with the prior art, the advantages of this utility model are: this turntable clamp adopts a mechanical structure to control the opening and closing operation between the movable clamping block and the fixed clamping block. The switch housing is clamped and fixed by the spring force acting on the movable clamping block through the cooperation of the movable clamping block and the fixed clamping block. There is no need to use an electric push rod to control the movement of the movable clamping block, which reduces the manufacturing cost of the turntable clamp and also saves the cost of daily maintenance of the electric push rod ring brush.

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Figure 1 This is a top view of the present invention.

[0012] Figure 2 yes Figure 1 Enlarged structural diagram at point M.

[0013] Figure 3 yes Figure 2 Enlarged structural diagram at point N. Detailed Implementation

[0014] The present invention will now be described in detail with reference to specific embodiments:

[0015] like Figures 1 to 3 The switch assembly turntable fixture shown includes a lower fixed plate 1, an upper turntable 2 and tooling fixtures 3. The upper turntable 2 is rotatably mounted on the lower fixed plate 1, and several tooling fixtures 3 are fixedly arranged in a ring array on the upper turntable 2.

[0016] The tooling fixture 3 consists of a base 4, a fixed clamping block 5, a movable clamping block 6, a guide rod 7, a spring 71, a drive rod 8, and a guide column 91. The base 4 is fixedly installed on the upper turntable 2. A connecting plate 42 is fixedly installed on the outer end of the base 4. The base 4 has a groove in the middle. The fixed clamping block 5 is fixedly installed in the groove of the base 4. The movable clamping block 6 is slidably installed in the groove of the base 4. Two guide rods 7 and one drive rod 8 are slidably installed in the connecting plate 42. The inner ends of the guide rods 7 and the drive rod 8 are fixedly connected to the movable clamping block 6. The spring 71 is sleeved on the guide rod 7. The inner and outer ends of the spring 71 act on the movable clamping block 6 and the connecting plate 42, respectively. Two guide columns 91 are fixedly installed at two adjacent tooling fixture 3 positions on the upper turntable 2, respectively, which are the unloading position and the loading position. An inclined guide groove 81 is provided on the bottom surface of the drive rod 8.

[0017] A pad 9 is screwed and fixedly installed on the lower fixed plate 1, and the guide post 91 is fixedly installed on the top of the pad 9. Since the diameter of the guide post 91 is 5-8mm, its installation strength is reduced when it is directly installed on the lower fixed plate 1 because its height exceeds 100mm. In actual use, the guide post 91 is prone to tilting. By setting the pad 9, the height of the guide post 91 is reduced to 5-15mm, thereby improving its structural strength after installation.

[0018] The clamping surfaces of the fixed clamping block 5 and the movable clamping block 6 are provided with arc groove structures. The arc groove structures can increase the contact area with the switch housing 10, making the clamping and fixing of the switch housing 10 more secure.

[0019] The inlet and outlet of the inclined guide groove 81 are both designed with rounded corners. The rounded corners can guide the guide post 91 into the inclined guide groove 81 and avoid blockage.

[0020] Taking the automated assembly operation where one of the tooling fixtures 3 rotates clockwise with the upper turntable 2 as an example, the two adjacent tooling fixture 3 positions on the upper turntable 2, where the guide column 91 is fixedly installed, are the unloading position and the loading position. When the switch housing 10 is loaded or unloaded, the upper turntable 2 stops rotating. After the tooling fixture 3 with the switch housing 10 clamped is automatically assembled, the guide column 91 at the unloading position slides into the inclined guide groove 81 of the tooling fixture 3 drive rod 8, and this tooling fixture 3 continues to rotate clockwise with the upper turntable 2. As the needle rotates, during the process of the guide post 91 sliding to the upper position of the inclined guide groove 81, the drive rod 8 pulls the combination of the movable clamping block 6 and the guide rod 7 to move outward against the elastic force of the spring 71. The movable clamping block 6 releases the clamping force on the switch housing 10, so that the automated robot can grab and unload the switch housing 10. After the guide post 91 slides out from the upper end of the inclined guide groove 81, under the action of the spring 71, the movable clamping block 6 moves inward and cooperates with the fixed clamping block 5 to clamp and fix the switch housing 10. The tooling fixture 3 continues to rotate clockwise with the upper turntable 2 to the loading station. The operation mode of the combination of the drive rod 8 and the movable clamping block 6 and the guide rod 7 is the same as that at the unloading station. At the loading station, the automated robot grabs the switch housing 10 and loads it between the fixed clamping block 5 and the movable clamping block 6.
