Abstract
Description
Technical Field
[0001] This utility model relates to a positioning device, and more specifically, to a positioning device for transformer testing. Background Technology
[0002] During the comprehensive testing of a transformer, after the transformer is placed on the test fixture, two vertical pusher cylinders are used to push and clamp the transformer pins. However, during the pushing process, if the two pusher cylinders are out of sync, the pusher cylinder located in the direction of the long hole of the test fixture will push the transformer along the long hole, making it impossible to accurately discharge the transformer afterwards. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a simple positioning device for transformer testing that ensures the transformer is accurately placed on the track.
[0004] The technical solution of this utility model is implemented as follows: a positioning device for transformer testing includes a testing fixture, the testing fixture having several elongated holes that mate with transformer pins, a positioning cylinder connected to one side of the testing fixture perpendicular to the direction of the elongated holes, a discharge guide rail on one side of the testing fixture perpendicular to the direction of the elongated holes, a pushing mechanism parallel to the direction of the elongated holes on one side of the testing fixture, and a stop block on one end of the testing fixture along the forward direction of the pushing mechanism.
[0005] Baffles are provided on both sides of the discharge guide rail along its length, and the inner end face of the baffle block does not exceed the inner surface of the baffle on the side away from the pushing mechanism; a transfer assembly is provided between the test fixture and the discharge guide rail.
[0006] In the aforementioned positioning device for transformer testing, the discharge guide rail has a buffer layer made of flexible material at the end near the testing fixture.
[0007] In the aforementioned positioning device for transformer testing, the baffle has a funnel-shaped guide portion at one end near the test fixture.
[0008] In the aforementioned positioning device for transformer testing, the pushing mechanism includes a pushing cylinder disposed on one side of the testing fixture, and a rubber pad is provided at the front end of the piston rod of the pushing cylinder.
[0009] In the above-mentioned positioning device for transformer testing, the transfer component is arranged on a two-dimensional moving platform on one side of the test fixture. The moving direction of the two-dimensional moving platform is vertical movement and horizontal movement between the test fixture and the discharge guide rail. A rotary motor is provided on the moving end of the two-dimensional moving platform, and a pneumatic gripper for clamping the transformer is provided on the rotary motor.
[0010] With the above-mentioned structure, this utility model restricts the transformer by using a baffle block. When the positioning cylinder and the pushing mechanism push the transformer from two directions at the same time, it can ensure that the transformer will not move along the long hole to a place that deviates from the discharge guide rail, and ensure that the transfer component can accurately place the transformer on the discharge guide rail to avoid it falling.

[0015] See Figure 1-2 As shown, this utility model discloses a positioning device for transformer testing, comprising a testing fixture 1. The testing fixture 1 has several elongated holes 2 that mate with transformer pins. A positioning cylinder 3 is connected to one side of the testing fixture 1 perpendicular to the direction of the elongated holes 2. A discharge guide rail 4 is provided on the same side of the testing fixture 1 perpendicular to the direction of the elongated holes 2. A pushing mechanism 5 parallel to the direction of the elongated holes 2 is provided on one side of the testing fixture 1. A stop block 6 is provided on one end of the testing fixture 1 along the forward direction of the pushing mechanism 5. The specific structure of the testing fixture is prior art, including a base, a movable carrier plate, and external testing equipment connected thereto. This is common knowledge to those skilled in the art and will not be described in detail here.
[0016] Baffles 7 are provided on both sides of the discharge guide rail 4 along its length. The inner end face of the baffle block 6 does not exceed the inner surface of the baffle 7 on the side away from the pushing mechanism 5. A transfer assembly 8 is provided between the test fixture 1 and the discharge guide rail 4. The baffle blocks restrict the transformer, ensuring that the transformer will not move along the long hole to a position deviating from the discharge guide rail when the positioning cylinder and the pushing mechanism push the transformer from two directions simultaneously. This ensures that the transfer assembly can accurately place the transformer on the discharge guide rail and prevent it from falling off.
[0017] The transfer component can also be equipped with a transfer structure that works with the front-end production line, so that the next loading process can be completed while the test fixture is being unloaded.
[0018] In this embodiment, a buffer layer 9 made of flexible material is provided at one end of the discharge guide rail 4 near the test fixture 1. By wrapping tape or cloth strips around the end of the discharge guide rail to create a buffer layer, the collision between the transformer and the surface of the discharge guide rail is reduced when the transformer is placed, thus avoiding damage.
[0019] In this embodiment, the baffle 7 has a trumpet-shaped inlet 10 at one end near the test fixture 1. The inlet facilitates the transformer's entry into the discharge guide rail for conveying.
[0020] In this embodiment, the pushing mechanism 5 includes a pushing cylinder 5a disposed on one side of the test fixture 1, and a rubber pad 5b is provided at the front end of the piston rod of the pushing cylinder 5a. The transformer is pushed by the rubber pad, which can adapt to deformation, to avoid excessive force during pushing that could damage the transformer.
[0021] In this embodiment, the transfer component 8 is disposed on a two-dimensional moving platform 8a on one side of the test fixture 1. The moving direction of the two-dimensional moving platform 8a is vertical movement and horizontal movement between the test fixture 1 and the discharge guide rail 4. A rotary motor 8b is provided on the moving end of the two-dimensional moving platform 8a, and a pneumatic gripper 8c for gripping the transformer is provided on the rotary motor 8b. A vertical gripper for loading is also provided on the two-dimensional moving platform to cooperate with the front-end production line. The two-dimensional moving platform can be driven by a lifting motor and gears, or by common drive structures such as cylinders. The specific structure is prior art and will not be described in detail here.
[0022] During operation, the transformer is placed onto the test fixture manually or by a transfer assembly. The piston rods of the positioning cylinder and the pushing cylinder extend synchronously to cooperate with the baffle block to clamp the transformer pins. The test fixture tests the transformer. After the test is completed, the piston rods of the positioning cylinder and the pushing cylinder retract, the two-dimensional moving platform moves the pneumatic gripper to grab the transformer, and then moves it to the discharge guide rail and flips it to place it on the buffer layer for discharge.
[0023] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
