Technical Field

[0001] The present invention relates to the technical field of adapter sleeve production, in particular to a heat treatment device for adapter sleeve production. Background Art

[0002] An adapter sleeve is a component commonly used to position a bearing with a tapered hole on a cylindrical shaft. It is widely used in many industries such as textiles, light industry, papermaking, metallurgy, belt transportation and conveying equipment. It plays an important supporting role in the normal operation of the equipment. In the production process of adapter sleeves, heat treatment is a key link.

[0003] Understanding the application of heat treatment equipment for current adapter sleeve production: During the production and processing of adapter sleeves, due to the influence of various factors, irregular round defective products often appear. Currently, there are many technical difficulties in dealing with such defective products: 1. Traditional shaping methods are difficult to accurately restore the internal shape of the adapter sleeve and cannot effectively solve the problem of local irregularities of the adapter sleeve, resulting in poor shaping effects and difficulty in making the adapter sleeve meet the requirements. 2. During the shaping and heat treatment process of the adapter sleeve, there is a lack of stable and reliable positioning and fixing devices, which makes the adapter sleeve prone to displacement or shaking during the treatment process, which not only affects the shaping and heat treatment effects, but may also cause further damage to the adapter sleeve.

[0015] After placing the adapter sleeve to be processed between the two positioning clamps, starting the positioning motor can rotate the positioning gear ring, driving the positioning slider and the positioning clamp to move toward each other, so that the adapter sleeve can be stably and reliably clamped and positioned. At the same time, when the sliding clamp is used to expand the adapter sleeve, by starting the cylinder B, the chuck can be clamped by utilizing the cooperation of the swing arm, rotating block A, rotating block B, clamping arm A and clamping arm B and other structures, thereby limiting the rotation of the entire transmission group, avoiding the rotational displacement of the adapter sleeve during the expansion process. This stable positioning and fixing method provides a reliable basis for the shaping and heat treatment of the adapter sleeve, ensuring the stability of the processing process and the quality of the adapter sleeve.

[0016] By adjusting the horizontal position of the flame heater and then starting cylinder A to move the flame heater up and down, the flame heater can be accurately adjusted to the appropriate position directly above the adapter sleeve. When the adapter sleeve is heated, it can help to evenly heat all parts of the adapter sleeve during the reset process, effectively avoiding expansion and damage caused by uneven heating. This flexible and uniform heating method improves the quality of the adapter sleeve heat treatment, reduces the defective rate, improves production efficiency and product qualification rate, and enables more defective adapter sleeves to reach qualified status through shaping and heat treatment.

[0028] Among them, a positioning frame 3 is fixedly installed in the middle position inside the instrument frame 1, and a lifting block 301 is slidably connected to the upper part of the front end of the positioning frame 3. A threaded hole is opened inside the lifting block 301, and a lifting screw 302 is rotatably connected to the front end of the positioning frame 3. The lifting screw 302 is located in the threaded hole of the lifting block 301.

[0029] Among them, the front end lower position of the lifting block 301 is fixedly connected to the top rear position of the positioning ring 303, the middle position of the positioning ring 303 is a through design, and the internal position of the positioning ring 303 is rotatably connected to the positioning gear ring 304, and a sliding groove is respectively opened on the left and right sides of the top of the positioning ring 303, and a positioning slider 305 is slidably connected in the two sliding grooves of the positioning ring 303.

[0030] Among them, an arc-shaped groove is provided at the top position of the positioning gear ring 304, and an arc-shaped tooth is provided at the bottom position of the positioning slider 305. The arc-shaped tooth position of the positioning slider 305 engages with the arc-shaped groove position of the positioning gear ring 304. A positioning splint 306 is fixedly installed at the outer position of the two positioning sliders 305, and an arc-shaped splint is provided at the lower end of the positioning splint 306. The two arc-shaped splints are located on both sides below the positioning ring 303. The positioning ring 303 is located directly below the processing seat 401. A positioning motor 307 is fixedly installed at the middle position of the front end of the positioning ring 303. The rotating shaft of the positioning motor 307 is provided with a bevel gear, and the bevel gear position of the positioning motor 307 engages with the positioning gear ring 304.

[0031] When using: Place the adapter sleeve to be processed in the middle position of the two positioning clamps 306, start the positioning motor 307, and the bevel gear on the rotating shaft of the positioning motor 307 engages with the positioning gear ring 304, causing the positioning gear ring 304 to rotate. The arc groove on the top of the positioning gear ring 304 engages with the arc teeth at the bottom of the positioning slider 305, driving the two positioning sliders 305 to slide in the sliding groove of the positioning ring 303, thereby causing the two positioning clamps 306 to move toward each other, clamping the adapter sleeve in place.

[0032] Rotate the lifting screw 302. Since the lifting screw 302 is located in the threaded hole of the lifting block 301, the lifting block 301 will move up and down above the front end of the positioning frame 3, adjusting the height of the positioning ring 303 and the adapter sleeve so that the bottom position of the adapter sleeve fits the top position of the processing seat 401 and the three curved plates of the processing slide clamp 404 are located inside the adapter sleeve. The processing motor 402 is started, and the bevel gear on the rotating shaft of the processing motor 402 engages with the lower position of the processing gear ring 403, causing the processing gear ring 403 to rotate. The spiral groove on the top of the processing gear ring 403 engages with the arc-shaped teeth on the bottom of the three processing slide clamps 404. As the processing gear ring 403 rotates, the three processing slide clamps 404 slide and expand in the three slide grooves of the processing base 401. The arc-shaped plates on their tops expand the interior of the adapter sleeve, thereby realizing the internal restoration operation of the adapter sleeve. The limit motor 201 is started, and the bevel gear on the rotating shaft of the limit motor 201 engages with the bevel gear of the transmission group 4, so that the transmission group 4 rotates, and the transmission group 4 drives the processing seat 401 to rotate to a suitable angle. When the three processing slide clamps 404 expand and restore the interior of the tightening sleeve, the current positions of the three processing slide clamps 404 can be changed, so as to ensure the restoration standard of the tightening sleeve in a wider range and avoid that a local position of the tightening sleeve is not affected by the expansion force.

[0033] When the three processing slide clamps 404 are expanding the fastening sleeve, in order to avoid the rotation of the transmission group 4, the cylinder B203 is started, and the cylinder B203 pushes the rotating block A205 to move upward. The swing arm 204 rotates with its rotating connection point with the bracket 202 as the axis, driving the rotating block B206 and the clamping arm A207 to move downward. The clamping arm A207 cooperates with the clamping arm B208 to clamp the chuck 405, thereby limiting the overall rotation of the transmission group 4, and avoiding the rotation displacement of the three processing slide clamps 404 during the expansion process.

[0034] The operating screw member 103 is rotated. Since the screw member 103 is located in the threaded hole of the horizontal sliding block 102, the horizontal sliding block 102 slides horizontally in the horizontal adjustment frame 101, and the horizontal position of the flame heater 105 is adjusted so that the flame heater 105 is located directly above the adapter sleeve. The cylinder A104 is started, and the cylinder A104 drives the flame heater 105 to move downward. The flame heater 105 is started to heat the adapter sleeve, which helps the adapter sleeve to be evenly heated in the process of resetting, thereby avoiding expansion and damage.

[0035] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure should be based on the protection scope of the claims.
