Description

Technical Field

[0001] This utility model relates to the field of guide sleeve processing technology, specifically to a guide sleeve clamping fixture adapted for internal hole turning. Background Technology

[0002] Mold guide bushings are solid lubricant products primarily used in the guiding system of molds to protect punches and dies, improving mold precision and lifespan. Their base material is often high-strength brass, inlaid with solid lubricants such as graphite or molybdenum disulfide, effectively reducing friction and wear even in oil-free or high-temperature environments. The product structure includes an integral design, combining flange positioning and positioning hole machining functions, making it suitable for various complex conditions such as high pressure, low temperature, and enclosed structures. As of 2025, mold guide bushings have been widely used in automotive molds, metallurgy, plastic injection molding machines, water conservancy projects, construction machinery, papermaking machines, shipbuilding, and other fields.

[0003] For example, CN221495355U discloses a guide sleeve clamping fixture adapted for internal turning. It includes a clamping fixture that is adapted and fixed to a hydraulic chuck. The clamping fixture comprises multiple clamping units arranged in an array along its center. Each clamping unit includes a fixing block and a clamping block. The clamping block is an arc-shaped block, and the fixing block is connected to the outer wall of the clamping block. The multiple clamping units together form a clamping station for clamping the guide sleeve within the inner wall of the clamping block. The fixing block is fixedly installed on the jaws of the hydraulic chuck. This clamping fixture is used to fix itself on the hydraulic chuck of a machine tool. By increasing the clamping contact area with the guide sleeve through the clamping blocks of the clamping units, the clamping stability of the guide sleeve is improved, reducing the risk of damage to the guide sleeve, resulting in more stable machining dimensions and improved yield. This clamping fixture is also adapted for use with diamond inserts for internal precision turning. Finally, the inner hole is opened by an internal diameter fixture before external diameter machining.

[0004] However, in implementing the relevant technology, the above-mentioned guide sleeve clamping fixture adapted for internal hole turning has the following problems: it is difficult to simultaneously tighten and clamp the inner and outer walls of the guide sleeve, resulting in the guide sleeve not being firmly fixed, reducing the stability of the guide sleeve clamping and fixing, and easily causing the guide sleeve to fall off during processing. It is also difficult to cover the guide sleeve during processing, resulting in the guide sleeve falling off and waste scattering and injuring workers, thereby reducing the safety of guide sleeve processing production. Therefore, a guide sleeve clamping fixture adapted for internal hole turning is proposed. Utility Model Content

[0005] This utility model proposes a guide sleeve clamping fixture suitable for internal hole turning, which solves the problem in related technologies that it is difficult to simultaneously tighten and clamp the inner and outer walls of the guide sleeve, resulting in an unstable guide sleeve fixation, reduced stability of the guide sleeve clamping and fixation, easy for the guide sleeve to fall off during processing, and difficulty in covering the guide sleeve during processing, leading to the guide sleeve falling off and waste material flying and injuring workers, thereby reducing the safety of guide sleeve processing production.

[0006] The technical solution of this utility model is as follows: A guide sleeve clamping fixture adapted for internal hole turning includes: a housing, a fixing plate fixedly installed on the top of the housing, a rotating mechanism disposed on the fixing plate, and a clamping fixture disposed at one end of the rotating shaft of the rotating mechanism.

[0007] The clamping fixture includes a fixed plate, a cross-shaped groove formed on the fixed plate, and four electric telescopic rods and four cylinders respectively fixedly installed inside the cross-shaped groove;

[0008] Each of the four cylinders has a push plate fixedly connected to its output end, and each of the four electric telescopic rods has a pull plate fixedly connected to its output end.

[0009] The protective mechanism is located on the top of the enclosure;

[0010] The cleaning mechanism is located between the containers.

[0011] Preferably, the rotating mechanism includes a motor fixedly mounted on the top of the housing, a gear one fixedly connected to the output end of the motor, and a gear two that rotates through the fixed plate via a rotating shaft.

[0012] Preferably, the protective mechanism includes a slide rail that is relatively fixedly installed on the top of the housing, and a transparent protective cover that is slidably connected to the slide rail.

[0013] Preferably, a toothed plate is fixedly installed on the lower rear side of the transparent protective cover, a fixing block is fixedly installed on the rear side of the box, a motor is fixedly installed on the top of the fixing block, and a gear three is fixedly connected to the output end of the motor, and the gear three is meshed with the toothed plate.

[0014] Preferably, the cleaning mechanism includes a support plate fixedly installed below the inner wall of the transparent protective cover, and a brush fixedly installed at the bottom of the support plate, the bristles of the brush being in contact with the top of the housing.

[0015] Preferably, the cleaning mechanism further includes a discharge trough extending through the top of the box body, and a collection box placed inside the box body, the collection box being located directly below the discharge trough.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. The electric telescopic rod drives the pull plate to retract, making the pull plate firmly adhere to the inner wall of the guide sleeve. Then, the cylinder is activated, which pushes the push plate forward, so that the push plate contacts the outer wall of the guide sleeve. The tension and clamping between the inner and outer walls effectively fixes the guide sleeve firmly, thereby improving the stability of the guide sleeve clamping and fixing, and effectively preventing the guide sleeve clamping mechanism from falling off.

[0018] Second, the motor drives the gear three to rotate, and the toothed plate connected in linkage drives the transparent protective cover to slide on the slide rail. This is used to cover the guide sleeve during processing, preventing the guide sleeve from falling off and waste from flying and injuring the workers, effectively improving the safety of guide sleeve processing.

[0031] Please see Figure 1 - Figure 4 A guide sleeve clamping fixture adapted for internal hole turning includes: a housing 1, a fixing plate 2 fixedly installed on the top of the housing 1, a rotating mechanism 3 set on the fixing plate 2, and a clamping fixture 4 set at one end of the rotating shaft of the rotating mechanism 3.

[0032] The clamping fixture 4 includes a fixed plate 41, a cross-shaped groove 42 formed on the fixed plate 41, four electric telescopic rods 43 and four cylinders 44 respectively fixedly installed inside the cross-shaped groove 42, a push plate 46 fixedly connected to the output end of each of the four cylinders 44, and a pull plate 45 fixedly connected to the output end of each of the four electric telescopic rods 43. The rotating mechanism 3 includes a motor 31 fixedly installed on the top of the housing 1, a gear 32 fixedly connected to the output end of the motor 31, and a gear 33 that passes through the fixed plate 2 through a rotating shaft.

[0033] This utility model provides a guide sleeve clamping fixture adapted for internal hole turning. By inserting the guide sleeve into the pull plate 45, activating the electric telescopic rod 43, the electric telescopic rod 43 drives the pull plate 45 to retract, so that the pull plate 45 is firmly attached to the inner side wall of the guide sleeve. Next, the cylinder 44 is activated, and the cylinder 44 pushes the push plate 46 forward, so that the push plate 46 contacts the outer side wall of the guide sleeve. Through the tension and clamping between the inner side wall and the outer side wall, the guide sleeve is effectively fixed firmly, thereby improving the stability of the guide sleeve clamping and fixing.

[0034] By starting the motor 31, the motor 31 drives the first gear 32 to rotate, and the second gear 33, which is in linkage with the motor, drives the rotating shaft to rotate, so that the clamping fixture 4 rotates, which is used to adjust the rotation of the guide sleeve.

[0035] Example 2

[0036] Based on Embodiment 1, this embodiment includes: a protective mechanism 5, which is disposed on the top of the housing 1. The protective mechanism 5 includes a slide rail 51 that is fixedly installed on the top of the housing 1, a transparent protective cover 52 that is slidably connected to the slide rail 51, a toothed plate 53 that is fixedly installed on the lower rear side of the transparent protective cover 52, a fixing block 54 that is fixedly installed on the rear side of the housing 1, and a motor 55 that is fixedly installed on the top of the fixing block 54. The output end of the motor 55 is fixedly connected to a gear 3 56, and the gear 3 56 is meshed with the toothed plate 53.

[0037] The technical solution provided in this embodiment is as follows: by starting the motor 55, the motor 55 drives the gear 3 56 to rotate, and the toothed plate 53 connected in linkage drives the transparent protective cover 52 to slide on the slide rail 51, which is used to cover the guide sleeve during processing, to prevent the guide sleeve from falling off and waste from flying and injuring the workers, thereby improving safety.

[0038] Example 3

[0039] Based on Embodiment 1, this embodiment includes: a cleaning mechanism 6, which is disposed between the boxes 1 and the boxes 1. The cleaning mechanism 6 includes a support plate 61 fixedly installed below the inner side wall of the transparent protective cover 52, a brush 62 fixedly installed at the bottom of the support plate 61, the bristles of the brush 62 being in contact with the top of the box 1, and the cleaning mechanism 6 also includes a discharge trough 63 that passes through the top of the box 1, and a collection box 64 placed inside the box 1, the collection box 64 being located directly below the discharge trough 63.

[0040] The technical solution provided in this embodiment is as follows: when the transparent protective cover 52 is opened, the brush 62 is driven to move to one side. When it moves, the brush 62 sweeps the waste generated by the processing of the guide sleeve at the top of the box 1 to the position of the discharge trough 63, so that the waste falls into the inside of the collection box 64 for collection, thereby achieving the purpose of cleaning the waste from the processing of the guide sleeve.
