Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a deformation-resistant support tooling for turning thin-walled bearing guide rings. Background Technology

[0002] The anti-deformation support fixture used for turning guide rings of thin-walled bearings mainly adopts a fan-shaped auxiliary fixture and a shaft protection positioning system, which achieves the anti-deformation effect by increasing the contact area and dispersing the clamping force.

[0003] To effectively prevent deformation of large towers, a large-scale anti-deformation support fixture for tower bodies has been developed (see patent number: 201711429752.X). This fixture includes: a support base plate; multiple telescopic parts arranged radially at equal angles, with one end of each telescopic part fixed to the support base plate and the other end supporting the inner wall of the large tower body; and a distance measuring device, including a signal transmitting unit and a signal receiving unit. The signal transmitting unit is located at the center of the support base plate, and the signal receiving unit receives information transmitted by the signal transmitting unit. The distance measuring device measures the distance from the central axis of the large tower body to its inner wall. The large-scale anti-deformation support fixture controls the multiple telescopic parts based on the measurement results from the distance measuring device.

[0004] However, existing anti-deformation support fixtures used for turning thin-walled bearing guide rings can cause excessive local stress on thin-walled parts, which can easily lead to deformation. When the thin-walled structure of the guide ring is radially clamped, the clamping force is concentrated at the edge of the workpiece, which can cause errors in the workpiece plane and reduce its utilization rate.

[0005] Therefore, a deformation-resistant support fixture for turning thin-walled bearing guide rings is proposed to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a deformation-resistant support fixture for turning thin-walled bearing guide rings in order to solve the problem of deformation or workpiece plane error caused by uneven clamping force.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a deformation-resistant support fixture for turning thin-walled bearing guide rings, comprising a fixed disk, support rods provided at the four corners inside the fixed disk, a sliding groove provided at one end of each support rod, an external tooling fixture provided at one end of the fixed disk, and an internal tooling fixture provided inside the external tooling fixture. Among them, a first motor is installed at the bottom of one side of the external tooling fixture, a first active screw is provided at the output end of the first motor, a first fixed ring is provided on both sides of the first active screw, a first driven screw is provided at the top of the first fixed ring, a first sliding block is threaded at the top and bottom of the first driven screw and extends to the other end of the sliding groove, and an external support plate is provided at the four corners of the other end of the fixed plate and fixedly connected to the first sliding block. All four sets of sliding grooves are inclined at 45° to the lower left and lower right. The inner tooling fixture has a second motor installed on the top of one side. The output end of the second motor is provided with a second driving screw. The two sides of the second driving screw are provided with second fixing rings. The bottom of the second fixing ring is provided with a second driven screw. The top and bottom of the second driven screw are threaded with a second sliding block extending to the other end of the sliding groove. The other four corners of the fixed plate and the inner side of the outer support plate are provided with an inner support plate that is fixedly connected to the second sliding block.

[0008] As a further aspect of the present invention: both sides of the first driving screw and the second driving screw are provided with leftward and rightward external spiral patterns, and the top and bottom ends of the first driven screw and the second driven screw are provided with upward and downward external spiral patterns.

[0009] As a further embodiment of the present invention: each of the two sets of first sliding blocks has an inner spiral thread to the left and right that matches the first active screw on one side, and both sets of first sliding blocks are threadedly connected to the first active screw.

[0010] As a further embodiment of the present invention: each of the two sets of second fixing rings is provided with a leftward and rightward internal spiral thread matching the second driving screw on one side, and both sets of second fixing rings are threadedly connected to the second driving screw.

[0011] As a further embodiment of the present invention: each of the upper and lower sets of the first sliding block and the second sliding block is respectively provided with upward and downward external spiral threads that match the first driven screw and the second driven screw, and the first sliding block and the second sliding block are both threadedly connected to the first driven screw and the second driven screw.

[0012] As a further embodiment of the present invention: mounting plates are provided on the top and bottom of one side of the fixed plate, and the first motor and the second motor are respectively mounted on the top of the mounting plates.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By having the output end of the first motor directly carry the first driving screw, the first fixed ring, the first driven screw and the first sliding block to move, and directly carry the outer support plate to retract inward along the sliding groove and move to the outer wall of the thin-walled bearing guide ring, the clamping of the outer side of the thin-walled bearing guide ring is realized, thereby realizing the tooling clamping operation of the outer side of the thin-walled bearing guide ring. 2. By reversing the rotation direction of the output end of the second motor, the second driving screw, the second fixed ring, the second driven screw, and the second sliding block can be directly moved. Simultaneously, the inner support plate is also directly moved outward along the sliding groove and onto the inner wall of the thin-walled bearing guide ring, thus achieving clamping of the thin-walled bearing guide ring. This method allows for the fixing of thin-walled bearing guide rings of different diameters, increasing the clamping range. Furthermore, the simultaneous internal and external clamping prevents deformation under stress, improving clamping stability. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0017] Please see Figures 1-5 In this embodiment of the invention, a deformation-resistant support fixture for turning thin-walled bearing guide rings includes a fixed disk 1, with support rods 101 provided at the four corners inside the fixed disk 1, a sliding groove 102 provided at one end of the support rods 101, an outer tooling fixture 2 provided at one end of the fixed disk 1, and an inner tooling fixture 3 provided inside the outer tooling fixture 2. Among them, a first motor 201 is installed at the bottom of one side of the external tooling fixture 2. A first active screw 202 is provided at the output end of the first motor 201. A first fixing ring 203 is provided on both sides of the first active screw 202. A first driven screw 204 is provided at the top of the first fixing ring 203. A first sliding block 205 extending to the other end of the sliding groove 102 is threaded at the top and bottom of the first driven screw 204. An external support plate 206 fixedly connected to the first sliding block 205 is provided at the four corners of the other end of the fixed plate 1. The four sets of sliding grooves 102 are all inclined at 45° to the lower left and lower right.

[0018] In this embodiment, the sliding grooves 102, which are inclined at 45° to the lower left and lower right, better restrict the range of motion of the outer support plate 206 and the inner support plate 306, allowing the four sets of outer support plates 206 and the four sets of inner support plates 306 to expand and contract simultaneously with the center point as the base point. This reduces the difficulty of operation. Furthermore, the first active screw 202, the first driven screw 204, the second active screw 302, and the second driven screw 304 used to support the outer support plate 206 and the inner support plate 306 can form a stable triangular structure with the outer support plate 206 and the inner support plate 306, thereby improving its stability during tooling clamping and support and enhancing the firmness of operation. Among them, a second motor 301 is installed on the top of one side of the inner tooling fixture 3. A second driving screw 302 is provided at the output end of the second motor 301. A second fixing ring 303 is provided on both sides of the second driving screw 302. A second driven screw 304 is provided at the bottom of the second fixing ring 303. A second sliding block 305 extending to the other end of the sliding groove 102 is threaded at the top and bottom of the second driven screw 304. An inner support plate 306 fixedly connected to the second sliding block 305 is provided at the four corners of the other end of the fixed plate 1 and on the inner side of the outer support plate 206.

[0019] like Figures 1 to 5 As shown, both sides of the first driving screw 202 and the second driving screw 302 are provided with leftward and rightward external spiral patterns, and the top and bottom of the first driven screw 204 and the second driven screw 304 are provided with upward and downward external spiral patterns.

[0020] like Figures 1 to 5 As shown, each of the two sets of first sliding blocks 205 has a leftward and rightward internal spiral pattern on one side that matches the first active screw 202, and both sets of first sliding blocks 205 are threadedly connected to the first active screw 202.

[0021] In this embodiment, the leftward and rightward internal spiral grooves are used so that the first sliding block 205 can be driven by the first active screw 202, and the two adjacent sets of first sliding blocks 205 can be moved downward or upward. The internal spiral groove holes on the first sliding block 205 are arranged longitudinally, so that it can be moved upward or downward better and improve the sufficient activity space.

[0022] like Figures 1 to 5 As shown, each of the two sets of second fixing rings 303 has a matching leftward and rightward internal spiral thread on one side of the second driving screw 302, and both sets of second fixing rings 303 are threadedly connected to the second driving screw 302.

[0023] In this embodiment, the second fixing ring 303 can move horizontally to the left or right along the second driving screw 302 when subjected to force, which facilitates the adjustment of the position of the second driven screw 304.

[0024] like Figures 1 to 5 As shown, each of the upper and lower sets of first sliding blocks 205 and second sliding blocks 305 is provided with upward and downward external spiral threads that match the first driven screw 204 and the second driven screw 304 respectively. The first sliding block 205 and the second sliding block 305 are threadedly connected to the first driven screw 204 and the second driven screw 304.

[0025] In this embodiment, when the first sliding block 205 and the second sliding block 305 are moved under force, they will move along the inclined direction of the sliding groove 102. At the same time, both sets of first driven screws 204 and second driven screws 304 move horizontally to the left or right. The moving first driven screws 204 and second driven screws 304 can be restricted by the first sliding block 205 and the second sliding block 305, so that they are always in an active connection with the fixed disk 1. The first sliding block 205 and the second sliding block 305 located on the first driven screw 204 and the second driven screw 304 can be moved vertically upward or downward under force. Combined with the restriction of the sliding groove 102, the first sliding block 205 and the second sliding block 305 can be tilted under force to achieve the effect of expansion or contraction.

[0026] like Figures 1 to 5 As shown, mounting plates are provided on the top and bottom of one side of the fixed plate 1. The first motor 201 and the second motor 301 are respectively mounted on the top of the mounting plates, which facilitates the fixing of the first motor 201 and the second motor 301.

[0027] Working principle: In use, the thin-walled bearing guide ring is placed between the outer support plate 206 and the inner support plate 306. Then, the output end of the first motor 201 drives the first driving screw 202 to rotate under the action of electricity. Since the bottom of the first driven screw 204 is threadedly connected to the first driving screw 202 through two sets of first fixing rings 203 and left- and right-facing internal spiral threads (the outer sides of the first driving screw 202 are provided with left- and right-facing external spiral threads, and the top and bottom of the outer side of the first driven screw 204 are provided with upward and downward external spiral threads), the bearing guide ring is able to rotate on both sides. The first driven screw 204 generates a pulling force, causing the two sets of first driven screws 204 to move in opposite directions. Then, due to the threaded connection between the first sliding block 205 and the first driven screw 204, the upper and lower sets of outer support plates 206 can move in opposite directions. At the same time, affected by the inclined range of the sliding groove 102, the four sets of outer support plates 206 can move towards the center point of the fixed plate 1, thereby allowing the four sets of outer support plates 206 to move better to the outside of the thin-walled bearing guide ring and be located at the four corners, thus fixing and clamping the four corners of the thin-walled bearing guide ring. Then, by reversing the rotation direction of the output end of the second motor 301 in the same way, the second driving screw 302, the second fixed ring 303, the second driven screw 304, and the second sliding block 305 can be moved directly. At the same time, the inner support plate 306 is moved outward along the sliding groove 102 and moved to the inner wall of the thin-walled bearing guide ring, thereby achieving the clamping of the thin-walled bearing guide ring. This method can be used to fix thin-walled bearing guide rings of different diameters, which improves the clamping range. At the same time, the operation of clamping from both inside and outside can avoid deformation under force and improve the stability of clamping.

[0028] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
