Description

Technical Field

[0001] This invention belongs to the technical field of railway rail support castings. Specifically, this invention relates to an auxiliary device for processing railway rail support castings. Background Technology

[0002] A rail brace is a rail component installed on the outside of the rail. It is mainly used to counteract the lateral force between the wheel and the rail, and to prevent excessive lateral displacement of the rail when a train passes over a curved track, thus avoiding the rail from tipping over.

[0003] Rail braces are generally produced using casting technology. After casting, due to the rough surface and irregular shape of the casting, they cannot be used directly and require further processing. This necessitates the use of clamping devices to hold the rail brace casting in place for easy processing by operators. Furthermore, given the large quantity of rail braces produced, the clamping devices must be reusable, highly efficient, easy to operate, and have stable clamping accuracy. Additionally, because the surface of the rail brace casting is irregular, operators must constantly adjust the angle to process the planes of the rail brace casting at different angles. Summary of the Invention

[0004] The present invention aims to provide an auxiliary device for processing railway rail support castings that can be reused, has high clamping efficiency, stable clamping accuracy, and adjustable angle.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an auxiliary device for processing railway rail support castings, including a mounting base, a fixing component that can fix and adjust the angle of the rail support casting on the mounting base, a rotating ball inside the fixing component, a support rod on the rotating ball, a support plate at the top of the support rod, and a clamping device for fixing the rail support casting on the support plate.

[0006] The fixing component includes a spherical shell mounted on a mounting base, a rotating ball disposed inside the spherical shell, a socket at the bottom of the spherical shell that is inserted into the mounting base, a fixing rod inside the mounting base, the top end of the fixing rod being located inside the spherical shell and in contact with the rotating ball.

[0007] The top of the fixed rod is provided with an arc plate to support the rotating ball, the inner surface of the top of the ball shell is provided with a friction plate, and a support spring is provided between the bottom of the fixed rod and the inner wall of the mounting base.

[0008] The fixing rod passes through the socket, and a sleeve and a plug shaft are provided between the fixing rod and the mounting base. The support spring is fitted outside the sleeve and the plug shaft.

[0009] The mounting base has pressing rods on both sides, and a connecting shaft is provided between the pressing rods and the mounting base. The pressing rods are located at one end of the mounting base and are in contact with the socket.

[0010] The socket has a push groove on its side, one end of the pressing rod inside the mounting base is located in the push groove, and the other end of the pressing rod outside the mounting base is equipped with a pressing plate.

[0011] The top of the socket is hinged with a swivel ring, the side of the swivel ring is provided with a push plate, and the mounting base is provided with a slot that mates with the push plate.

[0012] The clamping device includes a main mold base and a secondary mold base set on the support plate. The main mold base has a contour block on the side near the secondary mold base, and the secondary mold base has a contour groove on the side near the main mold base. The main mold base has a slot that mates with the rail support casting.

[0013] The main mold base has mounting plates on both sides, and the mounting plates have first adjusting screws. The side of the secondary mold base has a second adjusting screw, and the end of the second adjusting screw extends into the contour groove.

[0014] A clamping method for an auxiliary device for machining railway rail support castings, implemented using such an auxiliary device, comprises the following steps: S1: Place the rail support casting between the main mold base and the auxiliary mold base, and insert the rail support casting into the contour groove and the slot respectively; S2: After the rail support casting is inserted, the rail support casting is fixed by the first adjusting screw and the second adjusting screw, in conjunction with the main mold base and the auxiliary mold base; S3: Push the pressing plate to drive the pressing rod to rotate. The pressing rod, together with the push groove, lifts the socket. After the ball shell is pushed up, the inner wall surface of the ball shell separates from the rotating ball. S4: After the rotating ball separates from the inner wall of the spherical shell, the support plate is rotated, thereby driving the support rod and the rotating ball to rotate. This allows the angle of the fixed rail support casting to be adjusted, making it easier for operators to process the rail support casting. S5: Press the push plate to lower the socket, then push the rotating ring to rotate and insert the push plate into the slot; S6: As the socket descends, the ball rises relative to the shell, and the ball contacts the friction pad on the inner wall surface of the shell, compressing the support spring.

[0015] The technical advantages of this invention are as follows: After the rail support casting is fixed by the clamping device, the angle of the rail support casting can be adjusted by rotating the clamping device and the support plate, which facilitates the operator to process the rail support casting. When the clamping device is rotated, the rotating ball will rotate inside the fixing part. After the angle is determined, the rotating ball can be fixed by the fixing part, thereby fixing the support plate and achieving the purpose of fixing the angle of the rail support casting. This can prevent the rail support casting from shaking during processing, and achieve the effect of fixing the processing while arbitrarily adjusting the processing angle.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] Please see Figure 1-6 An auxiliary device for processing railway rail support castings includes a mounting base 1. The mounting base 1 has a fixing member 2 for fixing and adjusting the angle of the rail support casting. A rotating ball 3 is located inside the fixing member 2. A support rod 4 is mounted on the rotating ball 3, and a support plate 5 is located at the top of the support rod 4. The fixing member 2 includes a spherical shell 201 mounted on the mounting base 1. The rotating ball 3 is located inside the spherical shell 201. A socket 202 is located at the bottom of the spherical shell 201 and is inserted into the mounting base 1. A fixing rod 203 is located inside the mounting base 1, with its top end positioned within the spherical shell 201 and aligned with the rotating ball 3. The top of the fixed rod 203 is provided with an arc plate 204 to support the rotating ball 3. The inner surface of the top of the ball shell 201 is provided with a friction plate 205. A support spring 206 is provided between the bottom of the fixed rod 203 and the inner wall of the mounting base 1. The fixed rod 203 passes through the socket 202. A sleeve 207 and a plug shaft 208 are provided between the fixed rod 203 and the mounting base 1. The support spring 206 is fitted outside the sleeve 207 and the plug shaft 208. A rotating ring 213 is hinged to the top of the socket 202. A push plate 214 is provided on the side of the rotating ring 213. A slot 215 that mates with the push plate 214 is provided on the mounting base 1.

[0020] The support plate 5 is provided with a clamping device 6 for fixing the rail support casting. The clamping device 6 includes a main mold base 61 and a secondary mold base 62 set on the support plate 5. The main mold base 61 is provided with a contour block 63 on the side near the secondary mold base 62. The secondary mold base 62 is provided with a contour groove 64 on the side near the main mold base 61. The main mold base 61 is provided with a slot 68 that mates with the rail support casting. Mounting plates 65 are provided on both sides of the main mold base 61. The mounting plates 65 are provided with a first adjusting screw 66. The side of the secondary mold base 62 is provided with a second adjusting screw 67. The end of the second adjusting screw 67 extends into the contour groove 64.

[0021] After the rail support casting is fixed in place by the clamping device 6, the support plate 5 is rotated. The support plate 5, through the support rod 4, drives the rotating ball 3 to rotate within the fixing part 2, thereby adjusting the angle of the rail support casting. This facilitates the operator's processing of the rail support casting. After the angle is adjusted, the rotating ball 3 is fixed in place by the fixing part 2. Once the rotating ball 3 is fixed by the fixing part 2, the support rod 4 and the support plate 5 achieve the effect of fixing the clamping device 6 and the rail support casting clamped by the clamping device 6, preventing the rail support casting from shaking during operator processing. In this situation, since the rotating ball 3 is located inside the spherical shell 201 and is placed at the top of the fixed rod 203, when the socket 202 moves the spherical shell 201 downward, the rotating ball 3 rises relatively inside the spherical shell 201. The rotating ball 3 comes into contact with the inner wall of the spherical shell 201, and the friction generated by the mutual pressure between the rotating ball 3 and the spherical shell 201 fixes the rotating ball 3, thereby preventing the rotating ball 3 from rotating. The arc plate 204 can better push the rotating ball 3 to move and can reduce the slippage of the rotating ball 3 relative to the fixed rod 203. In the event of this situation, a support spring 206 is installed at the bottom of the fixing rod 203. On the one hand, this prevents the rotating ball 3 from being squeezed between the ball shell 201 and the socket 202 due to the large descent of the socket 202, thus avoiding breakage. On the other hand, the outward elasticity of the support spring 206 increases the pressure between the rotating ball 3 and the ball shell 201. Combined with the friction plate 205 installed inside the ball shell 201, this increases the friction and further prevents the rotating ball 3 from rotating. Through the cooperation of the sleeve 207 and the insertion shaft 208, and with the joint action of the socket 202, the fixing rod 203 can be prevented from tilting or breaking. The presence of the push plate 214 makes it easy for the operator to push the socket 202 down. When the socket 202 is pushed down to the bottom, the push plate 214 can be rotated and inserted into the slot 215. The cooperation between the slot 215 and the push plate 214 fixes the socket 202, preventing the socket 202 from rising back and causing the rotating ball 3 to be unable to be properly fixed.

[0022] Using the main mold base 61 and the auxiliary mold base 62, along with the contour block 63 and the contour groove 64, the rail support casting is clamped. At the same time, the slot 68 on the main mold base 61 can position the rail support casting and also assist the contour block 63 and the contour groove 64 in further fixing the position of the rail support casting. After the rail support casting is placed, by tightening the first adjusting screw 66 and the second adjusting screw 67, the rail support casting can be fixed on the main mold base 61 and the auxiliary mold base 62, thus achieving the purpose of clamping the rail support casting.

[0023] The mounting base 1 has pressing rods 209 on both sides, and a connecting shaft 210 is provided between the pressing rods 209 and the mounting base 1. One end of the pressing rod 209 is in contact with the socket 202. By pressing the pressing rod 209, the pressing rod 209 is pushed to rotate, and the pressing rod 209 rotates around the connecting shaft 210, so that the pressing rod 209 can push the socket 202 up and pull the socket 202 out of the mounting base 1.

[0024] The socket 202 has a push groove 212 on its side. One end of the pressing rod 209 located inside the mounting base 1 is located in the push groove 212, and the other end of the pressing rod 209 located outside the mounting base 1 is equipped with a pressing plate 211. The pressing plate 211 allows the operator to push the pressing rod 209 to rotate. Since the end of the pressing rod 209 located inside the mounting base 1 is located in the push groove 212, when the pressing rod 209 rotates, the end of the pressing rod 209 located in the push groove 212 will move to the inner wall of the push groove 212, thereby using the push groove 212 to push the socket 202 up.

[0025] A clamping method for an auxiliary device for machining railway rail support castings, implemented using such an auxiliary device, comprises the following steps: S1: Place the rail support casting between the main mold base 61 and the auxiliary mold base 62. The shape of the rail support casting matches the contour block 63 and the contour groove 64. Use the contour block 63 and the contour groove 64 to initially fix the position of the rail support casting. At the same time, use the slot 68 on the main mold base 61 to achieve a further fixing effect. S2: After the rail support casting is inserted, tighten the first adjusting screw 66 and the second adjusting screw 67. The first adjusting screw 66 and the second adjusting screw 67 move inward and come into contact with the surface of the rail support casting. The rail support casting is fixed by the first adjusting screw 66 and the second adjusting screw 67. S3: After fixing the rail support casting, rotate the push plate 214 to unscrew it from the slot 215. After unscrewing the push plate 214, press the pressing rod 209. The pressing rod 209 is pushed to rotate around the connecting shaft 210. The other end of the pressing rod 209 moves in the push groove 212. After the end of the pressing rod 209 moves to the inner wall surface of the end of the push groove 212, the pressing rod 209 pushes the socket 202 to rise. The socket 202 pushes the ball shell 201 to rise. The rotating ball 3 descends relative to the ball shell 201. The rotating ball 3 separates from the ball shell 201. S4: After the rotating ball 3 separates from the inner wall of the spherical shell 201, the support plate 5 is rotated, thereby driving the support rod 4 and the rotating ball 3 to rotate, which can adjust the angle of the fixed rail support casting, making it easier for the operator to process the rail support casting; S5: Press the push plate 214 to push the socket 202 down, then push the rotating ring 213 to rotate, insert the push plate 214 into the slot 215, fix the push plate 214 and the socket 202, and prevent the socket 202 from rising back; S6: As the socket 202 descends, the rotating ball 3 rises relative to the spherical shell 201. The rotating ball 3 contacts the friction plate 205 on the inner wall surface of the spherical shell 201, and the support spring 206 is compressed. Using the force of the support spring 206, the rotating ball 3 is lifted up, increasing the pressure between the rotating ball 3 and the spherical shell 201 and the friction plate 205, thereby achieving the effect of fixing the rotating ball 3 and preventing the rotating ball 3 and the rail support casting from rotating.

[0026] The technical effect of this invention is as follows: After the rail support casting is fixed by the clamping device 6, the angle of the rail support casting can be adjusted by rotating the clamping device 6 and the support plate 5, which facilitates the operator to process the rail support casting. When the clamping device 6 is rotated, the rotating ball 3 will rotate within the fixing part 2. After the angle is determined, the rotating ball 3 can be fixed by the fixing part 2, thereby fixing the support plate 5, achieving the purpose of fixing the angle of the rail support casting. This can prevent the rail support casting from shaking during processing, and achieve the effect of fixing the processing while arbitrarily adjusting the processing angle.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
