Description

TECHNICAL FIELD

[0001] The application relates to the technical field of transformer assembly, in particular to a tooling plate. BACKGROUND

[0002] An oil-immersed transformer, as a key component in the power system, has a precise and complex structure, and is usually composed of a box body, an embedded iron core and a box cover covering the opening of the box body, and the like. On the box cover, high-voltage porcelain bottles and low-voltage porcelain bottles are installed for the need of electrical connection. Before installing these porcelain bottle structures, a crucial step is to stably fix the box cover on a tooling plate so as to smoothly perform subsequent operations.

[0003] The traditional tooling plate design is relatively simple, mainly composed of a base plate and three limiting blocks fixed on the base plate. In actual operation, the box cover is clamped between the three limiting blocks, and the stability of the box cover during installation of the porcelain bottle structure is ensured through physical constraint of the outer edge of the box cover by the limiting blocks, so as to prevent installation errors caused by shaking or displacement of the box cover.

[0004] However, this design has a significant limitation: when facing different sizes of box covers, since the positions and sizes of the limiting blocks are fixed, adaptive adjustment cannot be made according to the actual size of the box cover. Therefore, in order to meet the tooling requirements of different box covers, the entire tooling plate often needs to be replaced. This process not only consumes time and effort, increases the time cost of production preparation, but also may cause waste of tooling resources, reduces the overall assembly efficiency, and has room for improvement. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the application is to provide a tooling plate to solve the problem that the above tooling plate cannot meet the limiting requirements of different box covers.

[0006] The tooling plate provided by the application adopts the following technical scheme:

[0007] A tooling plate, comprising a base plate and a center rod fixed in the middle of the base plate, a plurality of support plates are uniformly fixed on the base plate along the horizontal direction around the center rod axis, two receiving plates with upper sides capable of abutting against the bottom side of the box cover are relatively fixed on the support plates in the vertical direction; a limiting plate located between the two receiving plates is slidably arranged on the support plate in the horizontal direction, a limiting piece limiting the outer edge of the box cover is arranged on the side of the limiting plate away from the support plate; a locking through hole is formed in the limiting plate, a plurality of locking insertion holes are uniformly formed in the support plate in the direction close to the center rod, and a locking pin is embedded into the locking insertion hole through the locking through hole.

[0008] By adopting the technical scheme, when the sizes of the box covers of the tooling are different, the locking pin can be inserted into different locking holes by the staff, the distance between the limiting member and the center rod is adjusted, the limiting member can abut against and limit the outer edges of the box covers of different sizes, and the application range of the tooling plate is improved.

[0009] Optionally, the limiting member comprises two symmetrical connection rods fixed on the upper side of the limiting plate in the horizontal direction, the axis of the connection rod is towards the center rod, and the end of the two connection rods away from the center rod is hinged with an abutting rod; the rotating surface of the abutting rod is a vertical surface, and the abutting rod can reciprocatingly rotate towards the center rod; a tension spring is arranged above the supporting plate, and the two ends of the tension spring are fixedly connected with the end of the connection rod close to the center rod and the surface of the abutting rod respectively; a locking block is fixed on the side of the abutting rod towards the center rod and above the connection rod, and the locking block can abut against the side of the abutting rod away from the limiting plate under the action of the tension spring.

[0010] By adopting the technical scheme, since the locking block can abut against the side of the abutting rod away from the limiting plate under the action of the tension spring, and the abutting rod can rotate towards the center rod under the action of the tension spring, the side of the abutting rod towards the center rod can abut against the outer edge of the box cover, and the stability of the box cover in the tooling state is improved.

[0011] Optionally, the upper ends of the two connection rods are fixed with an abutting plate.

[0012] By adopting the technical scheme, since the abutting plate is installed, the side of the abutting plate towards the center rod can abut against the outer surface of the box cover, the abutting area of the abutting member and the outer edge of the box cover is increased, and the stability of the box cover in the tooling state is further improved.

[0013] Optionally, the upper end of the abutting rod is provided with a fixed notch for clamping the lower part of the abutting plate, the lower part of the abutting plate is provided with a fixed through hole, the inner wall of the fixed notch is provided with a fixed screw hole which can coincide with the fixed through hole, and the upper part of the supporting plate is provided with a fixed bolt which penetrates through the fixed through hole and is screwed into the fixed screw hole.

[0014] By adopting the technical scheme, when the abutting plate is installed on the abutting rod, the abutting plate is first clamped into the fixed notch on the abutting rod, the fixed through hole is coincided with the fixed screw hole, and then the fixed bolt is used to penetrate through the fixed through hole and is screwed into the fixed screw hole, so that the abutting plate is quickly installed.

[0015] Optionally, the side of the abutting plate towards the center rod is provided with a guide inclined surface at the upper edge.

[0016] By adopting the technical scheme, when the box cover is placed on the tooling table, the outer edge of the box cover is limited and positioned by the abutting plate and the guide inclined surface, and the outer edge of the box cover is limited and positioned along the guide inclined surface and the inner side of the abutting plate.

[0017] Optionally, two guide sliding rails are fixed on the support plate, two guide sliding blocks are symmetrically fixed on the side of the base plate, and guide sliding grooves are formed in the guide sliding blocks and used for the guide sliding rails to penetrate and slide.

[0018] By adopting the technical scheme, the stability of the limiting plate during sliding is improved by the cooperation of the guide sliding block and the guide sliding rail.

[0019] Optionally, limiting screws are fixed on the two end edges of the guide sliding rail.

[0020] By adopting the technical scheme, the guide sliding block is limited by the screw cap of the two limiting screws, and the possibility of the limiting plate being separated from the guide sliding rail during sliding is reduced.

[0021] Optionally, a wear-resistant pad is fixed on the side of the receiving plate away from the base plate.

[0022] By adopting the technical scheme, when the tooling plate limits the box cover, the wear-resistant pad on the receiving plate supports the bottom side of the box cover, so that the possibility of wear of the box cover during abutting with the side of the receiving plate is reduced.
