Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, specifically to a clamping device for removing burrs from risers using a six-split spacer bar frame for power fittings. Background Technology
[0002] Spacer bars are one of the main hardware components of overhead transmission lines. They separate multiple wires to prevent them from coming into contact with each other due to various factors, thus preventing damage to power transmission. Their structure mainly includes a frame, body, and cover plate. The main manufacturing process for six-split spacer bar frames is casting, which requires grinding at the riser (a riser is an additional part added to the top or side of a casting to prevent defects).
[0003] Common methods for grinding spacer bars typically involve manual grinding, requiring workers to first fix the spacer bar. Fixing methods include manual fixing and mechanical fixing. Manual fixing lacks positioning accuracy and easily leads to the spacer bar frame shifting during grinding, making both manual fixing and grinding time-consuming and labor-intensive. Mechanical fixing involves placing the spacer bar on a processing table and fixing it by tightening bolts to lower the clamping plates. However, fixing the spacer bar in all directions requires at least three clamping plates, necessitating three manual operations, further increasing time and labor intensity. Therefore, a six-split spacer bar frame riser burr removal fixture for power fittings is proposed to solve the aforementioned problems. Summary of the Invention
[0004] This utility model provides a six-split spacer frame fixture for removing riser burrs in power fittings, aiming to solve the technical problem that both manual and mechanical fixing are time-consuming and labor-intensive in related technologies.
[0005] This utility model discloses a six-split spacer frame for removing burrs from risers in power fittings. It includes a support platform, a base plate installed on the support platform, a plurality of positioning posts on the base plate, and a pressing unit located on one side of the base plate on the support platform. The pressing unit is used to fix the position of the six-split spacer frame.
[0006] The pressing unit includes a cylinder mounted on a support platform. A lifting rod is provided on the cylinder, and an installation rod is mounted on the lifting rod. Pressure blocks are connected to both ends of the installation rod facing the base plate.
[0007] Preferably, the mounting rod includes a mounting sleeve and telescopic rods inserted at both ends of the mounting sleeve. The mounting sleeve is rotatably connected to a lifting rod, and the two telescopic rods are slidably connected to both ends of the mounting sleeve. A driving device is provided on the lifting rod inside the mounting sleeve, and the driving device is used to drive the two telescopic rods to move relative to each other when the mounting sleeve rotates.
[0008] Preferably, the driving device includes a gear coaxially fixed to the end of the lifting rod away from the cylinder. The gear is located inside the mounting sleeve. Grooves are provided at the opposite ends of the two telescopic rods. A rack is provided in the groove. An accommodating space is formed between the two grooves. The gear is located in the accommodating space and meshes with the rack.
[0009] Preferably, a torsion spring sleeved on the lifting rod is provided between the gear and the mounting sleeve.
[0010] Preferably, there are two positioning posts, which are symmetrically arranged along the direction of the support platform. The six-split spacer frame has mounting holes at the hexagonal corners as positioning holes and are used in conjunction with the positioning posts.
[0011] Preferably, the positioning posts are three in number and arranged in an isosceles triangle, the inner wall of the six-split spacer frame is polygonal, and the positioning posts are in contact with the inner wall of the six-split spacer frame.
[0012] Preferably, the support platform has a linear groove, a screw is installed in the linear groove, and the base plate has fixing plates on both sides. The screw passes through the fixing plates and fixes the base plate in place.
[0013] Preferably, there are four fixing plates arranged symmetrically, and the fixing plates are L-shaped.
[0014] Preferably, the pressing unit further includes a base, on which a first hinge block and a second hinge block are hinged, and a pressure handle is hinged between the first hinge block and the second hinge block. A connecting arm is fixedly connected to the side of the second hinge block away from the first hinge block, and an adjustable pressure head is connected to the end of the connecting arm away from the connecting arm.
[0015] Compared with the prior art, this application has the following advantages:
[0016] 1. The positioning pins allow for precise positioning of the six-split spacer frame of any size, preventing positional deviations from affecting the grinding of the riser. Furthermore, the cylinder-driven descent of the pressure block on the mounting rod further secures the six-split spacer frame, replacing manual fixing and preventing movement during grinding that could reduce grinding accuracy.
[0017] 2. In this application, the installation sleeve is rotated so that the two telescopic rods move toward the inside of the installation sleeve, making the installation rods shorter so that the six-split spacer frame can pass through the installation rods, thus solving the problem that the six-split spacer frame is not easy to pass through the installation rods.

[0028] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0029] Example 1
[0030] like Figure 1 and Figure 8As shown, this utility model provides a fixture for removing burrs from risers on a six-split spacer frame for power fittings. It includes a support platform 1, with a burr removal device on top of the support platform 1 to achieve automated burr removal and improve the processing efficiency of the spacer frame. A base plate 2 is mounted on the support platform 1. Specifically, the support platform 1 has a linear groove 11, which is inverted T-shaped. Bolts are installed in the linear groove 11, with the bolt heads slidingly disposed within the groove. Nuts are provided on the bolt shanks located above the support platform 1. Fixing plates 12 are located on both sides of the base plate 2. Bolts pass through the fixing plates 12, fixing the base plate 2 in place. The cooperation of the fixing plates 12 and the bolts facilitates the installation or removal of the base plate 2. The fixing plate 12 has four symmetrically arranged plates, and the fixing plate 12 is L-shaped. The base plate 2 has several positioning posts 21. The hexagonal mounting holes on the six-split spacer frame 6 serve as positioning holes and cooperate with the positioning posts 21. Specifically, there are two positioning posts 21, symmetrically arranged left and right. The support platform 1 has a pressing unit located behind the base plate 2, which is used to fix the position of the six-split spacer frame 6. In another embodiment, there are three positioning posts 21 arranged in an isosceles triangle shape. The inner wall of the six-split spacer frame 6 is polygonal, and the contact between the positioning posts 21 and the inner wall of the six-split spacer frame 6 can also limit the position of the inner wall of the six-split spacer frame 6.
[0031] The pressing unit includes a cylinder 3 mounted on a support platform 1. Specifically, a mounting plate 301 is fixedly connected to the lower part of the cylinder 3. The mounting plate 301 is fixed to the support platform 1 by bolts and nuts. A rectangular groove is opened on the side of the base plate 2 facing the cylinder 3, and the mounting plate 301 is located in the rectangular groove. A lifting rod 31 is provided on the cylinder 3, and a mounting rod 4 is installed on the lifting rod 31. Specifically, the lifting rod 31 is a threaded rod, and nuts are threadedly connected to both the upper and lower sides of the lifting rod 31 of the mounting rod 4. The two nuts contact the outer surfaces of the upper and lower ends of the mounting rod 4 respectively to fix the position of the mounting rod 4. Pressure blocks 5 are fixedly connected to both ends of the mounting rod 4 facing the base plate 2.
[0032] Specifically, the base plate 2 can be installed or removed with the cooperation of the fixing plate 12 and bolts. It can use a suitable positioning post 21 to limit the position of the six-split spacer frame 6 according to its size, achieving precise positioning of the six-split spacer frame 6 of any size. This avoids positional deviations of the six-split spacer frame 6 affecting the grinding of its riser. The cylinder 3 drives the pressure block 5 on the mounting rod 4 to descend, pressing down the six-split spacer frame 6 and further fixing its position. This replaces manual fixing and prevents movement of the six-split spacer frame 6 during grinding, thus avoiding reduced grinding accuracy.
[0033] Example 2
[0034] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the mounting rod 4 includes a mounting sleeve 41 and telescopic rods 42 respectively inserted at both ends of the mounting sleeve 41. The mounting sleeve 41 is rotatably connected to the lifting rod 31. Specifically, there is a gap between the mounting sleeve 41 and the nut above the mounting sleeve 41 to facilitate the free rotation of the mounting sleeve 41 on the lifting rod 31. The two telescopic rods 42 are slidably connected to both ends of the mounting sleeve 41 respectively. The diameter of the telescopic rods 42 is adapted to the inner diameter of the mounting sleeve 41. A driving device is provided on the lifting rod 31 inside the mounting sleeve 41. The driving device is used to drive the two telescopic rods 42 to move relative to each other when the mounting sleeve 41 rotates.
[0035] The drive device includes a gear 32 coaxially fixed to the end of the lifting rod 31 away from the cylinder 3. The gear 32 is located inside the mounting sleeve 41. Each of the two telescopic rods 42 has a groove 421 at its opposite end, and a rack 422 is installed within the groove 421. A receiving space is formed between the two grooves 421, and the gear 32 is located within this space and meshes with the rack 422. A torsion spring 33 is sleeved on the lifting rod 31 between the gear 32 and the mounting sleeve 41. One end of the torsion spring 33 is fixed to the lifting rod 31, and the other end of the lifting rod 31 is fixed to the mounting sleeve 41. The torsion spring 33 facilitates the automatic reset of the mounting sleeve 41 after rotation.
[0036] Specifically, the installation sleeve 41 is rotated so that the two telescopic rods 42 move toward the inside of the installation sleeve 41, making the installation rod 4 shorter so that the six-split spacer frame 6 can pass through the installation rod 4, thus solving the problem that the six-split spacer frame 6 is not easy to pass through the installation rod 4.
[0037] Working principle of this utility model:
[0038] First, place the six-split spacer frame 6 on the base plate 2. Position the cylinder 3 in the middle of the six-split spacer frame 6 so that the positioning post 21 on the base plate 2 is located in the mounting hole on the six-split spacer frame 6, thus initially defining the position of the six-split spacer frame 6. Then, start the cylinder 3 so that the lifting rod 31 drives the pressure block 5 on the mounting rod 4 to descend and contact the six-split spacer frame 6, thereby fixing the position of the six-split spacer frame 6. Finally, use a grinding head to grind the riser of the six-split spacer frame 6, thus achieving the effect of mechanized grinding of the six-split spacer frame 6 and improving the grinding efficiency of the six-split spacer frame 6. After grinding one half of the six-split spacer frame 6, disassemble the six-split spacer frame 6 and rotate it to grind the other half.
[0039] Before placing the six-split spacer frame 6, the mounting sleeve 41 is rotated, which drives the telescopic rod 42 to rotate. At the same time, under the action of the gear 32 and the rack 422, the two telescopic rods 42 move towards each other. Meanwhile, the torsion spring 33 is twisted, thereby shortening the mounting rod 4 as a whole, so that the six-split spacer frame 6 can be quickly placed on the bottom plate 2. After the six-split spacer frame 6 is placed on the positioning post 21 on the bottom plate 2, the mounting sleeve 41 is released, and the two telescopic rods 42 are reset under the action of the torsion spring 33. Then, the position of the six-split spacer frame 6 is limited by the action of the cylinder 3.
[0040] Example 3
[0041] like Figure 6 and Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the pressing unit includes a base 61. Specifically, the base 61 is fixed to the support platform 1 by bolts and nuts. A first hinge block 63 and a second hinge block 64 are hinged to the base 61. Specifically, a positioning groove 62 is provided on the base 61, and the first hinge block 63 and the second hinge block 64 are located in the positioning groove 62 and connected by a mounting shaft. A pressure handle 65 is hinged between the first hinge block 63 and the second hinge block 64. The pressure handle 65 is prior art (not described in detail here). A connecting arm 66 is fixedly connected to the side of the second hinge block 64 away from the first hinge block 63. An adjustable pressure head 67 is connected to the end of the connecting arm 66 away from the connecting arm 66. The adjustable pressure head 67 is prior art (not described in detail here). The adjustable pressure head 67 can adjust the distance between itself and the base plate 2 to accommodate fixing six-split spacer frame 6 of different thicknesses.
[0042] Specifically, by rotating the pressure handle 65, the adjustable pressure head 67 rotates and comes into contact with the six-split spacer frame 6, thereby fixing the six-split spacer frame 6. This pressing unit is manually operated, which can reduce the consumption of electrical energy and can be used as a substitute when the cylinder 3 fails or the air pressure is insufficient.
