Description

Technical Field

[0001] This utility model relates to the field of rotary worktable technology, and in particular to a rotary worktable for precision flange production. Background Technology

[0002] Currently, with the continuous maturation of the machinery industry, flange connectors, as a widely used mechanical part, are well-known to people.

[0003] Traditional flange grinding equipment can perform horizontal grinding on the flange end face, thereby improving the sealing effect of the flange during use. However, traditional grinding equipment can only perform horizontal grinding on the flange end face. When it is necessary to use a raised face flange, the traditional equipment usually cannot grind it. However, since the outer arc surface area of ​​the raised face flange is larger than that of the flat face flange, the usage rate of raised face flanges is higher than that of flat face flanges in the application environment where high sealing performance is required for pipeline connection. Therefore, it is necessary to grind the outer arc surface of the raised face flange. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a rotary worktable for precision flange production.

[0005] This utility model is achieved by the following technical solution: a rotary worktable for precision flange production, including a base and a frustum provided on its top via a support column, a rotating component provided on the frustum, the rotating component including a turntable, and a fixed component provided on the top of the turntable;

[0006] The base has two lifting components slidably connected to its top. The two lifting components are symmetrically distributed on both sides of the truncated cone. One lifting component is connected to a lifting plate, and the other lifting component is connected to a rangefinder. The lifting plate is equipped with a grinding component.

[0007] As a further improvement to the above solution, the grinding component includes a rotating bracket connected to the bottom of the lifting plate. The rotating bracket has a rotating shaft A on its side, and an inclined component is sleeved on the rotating shaft A. A grinding component is connected to the bottom of the inclined component. An adjusting bracket is connected to the other end of the inclined component away from the rotating bracket. The adjusting bracket has a rotating shaft B on its side, and an adjusting screw is connected to the side of the rotating shaft B. A sliding abutment is slidably connected to the top of the lifting plate. A through groove is provided in the center of the lifting plate. The adjusting screw passes through the through groove and is rotatably connected to the sliding abutment. A nut is provided on the top of the sliding abutment, and the nut is threadedly connected to the adjusting screw.

[0008] As a further improvement to the above solution, the fixing component includes a sliding column, and the top of the turntable is provided with multiple sets of circumferentially distributed sliding grooves. The inner wall of the sliding groove is connected to the sliding column, and a spring is sleeved on the outer arc surface of the sliding column. One end of the spring is connected to the inner side wall of the sliding groove, and the other end of the spring is connected to an arc-shaped limiting member. The arc-shaped limiting member is slidably connected to the sliding column.

[0009] The above technical solution enables compatible adjustment of different types of raised flanges. By rotating the nut, the height of the adjusting screw can be adjusted. Furthermore, the combination of the nut and the reverse thread nut prevents the adjusting screw from sliding vertically during the grinding process, thereby ensuring the grinding accuracy of this device.

[0010] As a further improvement to the above solution, the rotating component includes a rotating motor disposed at the bottom of the truncated cone, the output end of the rotating motor passing through the truncated cone and connected to the turntable, and a plurality of supporting rollers connected to the top of the truncated cone, the top of the supporting rollers contacting the bottom of the turntable.

[0011] As a further improvement to the above solution, the bottom of the base is rotatably connected to several rollers, which are distributed at the four corners of the base.

[0012] Through the above technical solution, the structure of the rotating motor can drive the convex flange to rotate horizontally at high speed, thereby achieving uniform grinding of the outer arc surface of the convex flange. At the same time, the principle of conservation of angular momentum and the support of the supporting rollers can ensure that the flange will not tilt due to grinding vibration during the grinding process.

[0013] As a further improvement to the above solution, the base is connected to a rotating connector, and a horizontal screw is rotatably connected to the side of the rotating connector. The horizontal screw is threadedly connected to the bottom of the lifting bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, by setting up a rotating component, drives the flange to rotate at high speed, thereby reducing the vibration of the flange during the grinding process through the principle of conservation of angular momentum, thus improving the precision of the flange surface grinding.

[0016] This invention, by setting up a grinding component, can make targeted adjustments based on the different inclination angles of the outer arc surface of different convex flanges, thereby effectively improving the processing compatibility of convex flanges of different sizes and models.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0026] Please combine Figure 1-6 This embodiment of a rotary worktable for precision flange production includes a base 1 and a frustum 2 on its top via a support column. The frustum 2 is provided with a rotating component 3, which includes a turntable 303. The top of the turntable 303 is provided with a fixing component 4.

[0027] Specifically, the rotating component 3 includes a rotating motor 301 disposed at the bottom of the truncated cone 2. The output end of the rotating motor 301 passes through the truncated cone 2 and is connected to the turntable 303. Several supporting rollers 302 are connected to the top of the truncated cone 2. The top of the supporting rollers 302 contacts the bottom of the turntable 303. The structure of the rotating motor 301 can achieve the effect of driving the flange to rotate at high speed. At the same time, the structure of the supporting rollers 302 can support the high-speed rotating turntable 303, which helps to prevent the turntable 303 from tilting during the grinding process.

[0028] The base 1 has two lifting components 5 slidably connected to its top. The two lifting components 5 are symmetrically distributed on both sides of the truncated cone 2. One lifting component 5 is connected to a lifting plate 6, and the other lifting component 5 is connected to a rangefinder 7. The lifting plate 6 is equipped with a grinding component 8.

[0029] Furthermore, the grinding component 8 includes a rotating bracket 801 connected to the bottom of the lifting plate 6. A rotating shaft A is provided on the side of the rotating bracket 801, and an inclined component 802 is sleeved on the rotating shaft A. A grinding component 803 is connected to the bottom of the inclined component 802. An adjusting bracket 804 is connected to the other end of the inclined component 802 away from the rotating bracket 801. A rotating shaft B is provided on the side of the adjusting bracket 804, and an adjusting screw 805 is connected to the side of the rotating shaft B. A sliding abutment 807 is slidably connected to the top of the lifting plate 6. A through groove is provided in the center of the lifting plate 6, through which the adjusting screw 805 passes and slides against the groove. The component 807 is rotatably connected, and the top of the sliding abutment component 807 is provided with a nut 806. The nut 806 includes a positive thread nut and a negative thread nut. The negative thread nut is located above the positive thread nut. The positive thread nut and the negative thread nut are threadedly connected to the adjusting screw 805. The adjustable tilt angle grinding component 803 structure can effectively realize the compatibility of this device with convex flanges of different tapers. The combination of positive thread nut and negative thread nut fastening method can prevent the height of the adjusting screw 805 from changing during the grinding process, thereby fixing the tilt angle of the tilting component 802.

[0030] The fixing component 4 includes a sliding column 402. The top of the turntable 303 is provided with multiple sets of circumferentially distributed sliding grooves 401. The inner wall of the sliding groove 401 is connected to the sliding column 402. A spring 403 is sleeved on the outer arc surface of the sliding column 402. One end of the spring 403 is connected to the inner side wall of the sliding groove 401, and the other end of the spring 403 is connected to an arc-shaped limiting member 404. The arc-shaped limiting member 404 is slidably connected to the sliding column 402. Through the structure of the spring 403 and the arc-shaped limiting member 404, flanges of different diameters can be clamped and fixed, thereby improving the compatibility of this device with flanges of different diameters. At the same time, the circumferential clamping method can improve the uniformity of force on the flange in all directions and avoid the impact on the side of the flange during the clamping process.

[0031] The base 1 has several rollers rotatably connected to its bottom, and the rollers are distributed at the four corners of the base 1. The lifting assembly 5 includes a lifting bracket, a lifting motor is connected to the top of the lifting bracket, the lifting bracket is in the shape of an inverted U, and the bottom output end of the lifting motor passes through the lifting bracket and is connected to a lifting screw. The lifting screw is threadedly connected to the lifting plate 6, and the lifting plate 6 is slidably connected to the inner side wall of the lifting bracket.

[0032] The base 1 is connected to a rotating connector, and a horizontal screw is rotatably connected to the side of the rotating connector. The horizontal screw is threaded to the bottom of the lifting bracket.

[0033] The implementation principle of a rotary table for precision flange production in this embodiment is as follows: By placing the flange to be processed on the turntable 303, the device can easily limit and fix the flange material. After the flange material is placed, the arc-shaped limiting member 404 is manually pushed outward, so that the flange contacts the top of the turntable 303. At this time, several arc-shaped limiting members 404 contact and press with the side of the flange. The height of the arc-shaped limiting member 404 is lower than the thickness of the flange. The arc-shaped limiting member 404 clamps and limits the side of the flange under the action of the spring 403. The structure of the sliding column 402 can ensure that the arc-shaped limiting member 404 slides linearly and prevents the arc-shaped limiting member 404 from tilting or other problems.

[0034] After the flange is clamped and fixed, the rotating motor 301 in the rotating component 3 is started. The rotating motor 301 drives the turntable 303 to rotate, which in turn drives the flange to rotate horizontally at high speed. At this time, the top of the support roller 302 contacts the bottom of the turntable 303, thereby providing support for the turntable 303 and avoiding problems such as tilting of the turntable 303 during high-speed rotation.

[0035] When the flange is rotating horizontally at high speed, adjusting the lifting assembly 5 allows the lifting plate 6 to be positioned appropriately on the side of the turntable 303. At this time, the unlocking nut 806 allows the adjusting screw 805 to move up and down. By adjusting the lifting of the adjusting screw 805, the tilt angle of the tilting member 802 can be changed. Since one end of the tilting member 802 is rotatably connected to the rotating bracket 801, the movement trajectory of the tilting member 802 is an arc-shaped swing motion. Therefore, while the adjusting screw 805 is adjusting vertically, it slides inside the through groove, thus ensuring that the device will not jam during adjustment. When the adjusting screw 805 slides inside the through groove, the sliding abutment 807 slides along with the adjusting screw 805.

[0036] When the tilting component 802 is adjusted to a suitable tilt angle, the nut 806 is rotated. At this time, the bottom of the nut 806 contacts the sliding abutment 807, thus determining the current height of the adjusting screw 805. Then, the reverse nut is rotated, so that the reverse nut contacts and presses against the top of the nut 806, ensuring that the adjusting screw 805 will not loosen during the grinding process. After tightening, the horizontal screw can drive the lifting component 5 to move closer to the turntable 303, so that the grinding component 803 contacts the flange surface, thereby achieving the grinding effect.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
