Description

Technical Field

[0001] The invention relates to the technical field of automobile stabilizer bar processing, in particular to a stabilizer bar vulcanized bushing press-fitting and heating integrated equipment. Background Art

[0002] In the automobile suspension system, the stabilizer bar (also known as the anti-roll bar) plays a vital role. It can effectively reduce the body roll of the vehicle when turning, and improve the vehicle's handling stability and ride comfort. The working principle of the stabilizer bar is to connect the suspension on the left and right sides. When the suspension on one side of the vehicle is compressed, the stabilizer bar will transfer part of the force to the other side, thereby balancing the body posture. The bushing is a key component connecting the stabilizer bar to the frame or suspension. Its performance directly affects the performance of the stabilizer bar and the durability of the entire suspension system.

[0003] Bushings are usually made of rubber or composite materials to absorb vibration, reduce noise and allow necessary movement while maintaining a firm connection between components. To ensure reliable installation and long-term performance of bushings, the press-fit and vulcanization processes are critical steps.

[0004] In the traditional vulcanization process, press-fitting and heating are two independent stations, and the stabilizer bar needs to be transferred between the two stations, which not only increases the handling time, but also may cause the production line to stop and wait, greatly reducing production efficiency and extending the overall manufacturing cycle of the product. In addition, in the sub-station operation, each transfer of the stabilizer bar may introduce positioning errors, especially in the transfer process from press-fitting to heating. A slight change in the position of the bushing may affect the assembly accuracy and performance consistency of the final product.

[0005] Separate press-fitting and heating stations require additional space layout, which not only increases the factory floor space, but may also affect the optimization of the workshop logistics line and production layout. In addition, for changing product design requirements, traditional press-fitting and heating separation equipment often requires more customized molds and adjustment time, which limits the production line's ability to quickly adapt to new products and slows down the response to the market. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an integrated press-fitting and heating equipment for a stabilizer bar vulcanized bushing, so as to solve the problem that the press-fitting and heating are two separate workstations in the prior art, which reduces production efficiency and affects product assembly accuracy.

[0007] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0008] A stabilizer bar vulcanized bushing press-fitting and heating integrated equipment, comprising a base, two press-fitting heating devices symmetrically arranged on the left and right sides of the base through a spacing adjustment device, and a centering device arranged in the middle of the base;

[0009] Both of the press-fitting heating devices are provided with a temperature control device for real-time adjustment of the vulcanization temperature of the bushing;

[0010] The press-fit heating device is composed of a mounting seat, an upper press-fit heating component, a lower press-fit heating component and two conduction devices. The mounting seat is formed by a bottom machine seat, a side machine seat and a top machine seat. The upper press-fit heating component is arranged on the top machine seat, and the lower press-fit heating component is arranged on the bottom machine seat. The two conduction devices are symmetrically arranged at the front and rear ends of the lower press-fit heating component, and the conduction devices are used to form electrical conduction between the upper press-fit heating component and the lower press-fit heating component so as to facilitate heating of the bushing.

[0011] The centering device comprises a support seat arranged in the middle of the base, and a centering clamp movably mounted on the support seat and used for tightening the two ends of the stabilizing rod.

[0012] To implement the above technical solution, the distance between the two press-fitting heating devices is adjusted by the distance adjusting device, so as to facilitate the vulcanization of stabilizer bars of different sizes and specifications, thereby improving the practicality of the equipment; the temperature control device can separately control the temperature of the two press-fitting heating devices according to the temperature range set for vulcanization, so as to improve the vulcanization effect of the bushing; the centering fixture is movably installed on the support seat, so different centering fixtures can be easily replaced according to stabilizer bars of different specifications; during operation, the upper press-fitting heating assembly presses the stabilizer bar and the bushing onto the lower press-fitting heating assembly, and then the conduction device forms an electrical connection between the upper press-fitting heating assembly and the lower press-fitting heating assembly, thereby heating the bushing and the stabilizer bar; the present application integrates the press-fitting and heating processes of the stabilizer bar bushing, can be formed in one step, reduces the transfer time at the press-fitting and heating stations, improves processing efficiency, and can prevent the transfer of the stabilizer bar from causing precision errors, thereby ensuring the consistency and reliability of product quality.

[0013] In one embodiment of the present invention, the upper press-fit heating assembly includes a push device disposed on the push base, a push plate disposed on the output shaft of the push device, a guide assembly disposed between the push plate and the push base, and an upper press-fit body disposed at the lower end of the push plate;

[0014] The press-down heating assembly comprises a bottom plate arranged on the bottom machine seat, a guide plate arranged on the bottom plate, and a press-down body arranged in the middle of the guide plate.

[0015] To implement the above technical solution, during operation, the pushing device pushes the pushing plate downward, and enables the upper pressing body and the lower pressing body to align, thereby completing the pressing of the stabilizer bar and the bushing. The guide assembly can improve the precise positioning of the pushing device and ensure the stability of the pressing heating process.

[0016] In one embodiment of the present invention, the upper press-fit body and the lower press-fit body each include a press block, an inner lining body fixed on the press block, and an outer lining body nested outside the inner lining body, a groove is provided in the middle of the outer lining body, a press-fit sleeve is embedded in the groove, and a receiving cavity for placing a stabilizing rod and a bushing is provided on the press-fit sleeve;

[0017] The upper press-fit body also includes an upper heating plate disposed between the outer lining body and the inner lining body;

[0018] The lower press-fit body also includes a lower heating plate arranged between the outer lining body and the inner lining body.

[0019] To implement the above technical solution, the press-fitting sleeve is movably arranged on the outer lining body, so different press-fitting sleeves can be replaced according to stabilizer bars of different specifications, thereby improving the applicability of the equipment. During operation, the upper heating plate and the lower heating plate transfer heat to the outer lining body and further to the press-fitting sleeve, thereby completing the heating of the bushing and the stabilizer bar. The outer lining body and the press-fitting sleeve are preferably made of metal thermal conductive material to reduce the heat energy loss during the vulcanization process of the bushing. The inner lining body is made of insulating material to prevent leakage from causing short circuits and causing harm to equipment or human body. The conducting device is used to complete the electrical conduction between the upper heating plate and the lower heating plate. The specific working process is to conduct electricity on one of the conducting devices and then complete the electrical connection of the lower heating plate, the other conducting device, and the upper heating plate in turn, thereby ensuring the thermal efficiency of the vulcanized bushing and promoting the thermal uniformity of the vulcanization process.

[0020] In one embodiment of the present invention, guide grooves are symmetrically formed at both ends of the guide plate, and rectangular windows penetrating from top to bottom are formed at both ends of the guide plate close to the guide grooves.

[0021] The conduction device comprises a slider sliding on the guide groove, a mounting plate arranged on the slider, and a conduction component arranged on the mounting plate and capable of connecting the upper heating plate and the lower heating plate;

[0022] The conduction device also includes a conduction cylinder and a wedge-shaped block arranged on the output shaft of the conduction cylinder;

[0023] A large rectangular window of the same size as the rectangular window is provided at the lower end of the slider, a small rectangular window that penetrates the large rectangular window is provided at the upper end of the slider, and an inclined surface that fits the wedge block is connected between the large rectangular window and the small rectangular window;

[0024] Abutment plates are symmetrically arranged at both ends of the sliding block, and abutment blocks corresponding to the abutment plates are arranged on the bottom plate.

[0025] To implement the above technical solution, in the present application, a wedge-shaped block arranged on the conducting cylinder is brought into abutment with the inclined surface of the slider, so that the conducting component is brought into abutment with the upper heating plate and the lower heating plate, and an electrical connection is formed between the upper heating plate, the lower heating plate and the conducting component, which is convenient for vulcanization heating of the stabilizer bar bushing. Through the coordinated work of the slider, the guide plate, the conducting cylinder and the conducting component, rapid press-fitting and heating of the bushing are achieved. The setting of the abutment plate and the abutment block can effectively limit the maximum stroke of the slider, and at the same time can prevent the conducting component from being hard-abutted with the upper heating plate and the lower heating plate, which may cause surface damage or even poor connection.

[0026] In one embodiment of the present invention, the upper heating plate and the lower heating plate both include an annular portion, and the upper heating plate further includes upper positioning portions symmetrically arranged at both ends of the annular portion, and an upper positioning hole penetrating from top to bottom is opened in the middle of the upper positioning portion;

[0027] The lower heating plate further comprises lower positioning parts arranged at both ends of the annular part, and a lower positioning hole penetrating from top to bottom is opened in the middle of the lower positioning part;

[0028] The front and rear ends of the lower heating plate are both provided with positioning seats, and the positioning seats are provided with positioning pins that penetrate the lower positioning holes, and the positioning pins can be embedded in the upper positioning holes under the joint action of the conduction cylinder and the pushing device.

[0029] To implement the above technical solution, the present application further improves the structures of the upper heating plate and the lower heating plate. By setting the annular portion, the heating area of ​​the bushing can be effectively increased, thereby improving the vulcanization efficiency. The setting of positioning holes and positioning pins is introduced to achieve precise positioning and stable connection of the upper press-fit heating assembly and the lower press-fit heating assembly. The positioning seat is made of insulating material, which can effectively prevent leakage and cause harm to equipment or human body.

[0030] In one embodiment of the present invention, the conductive component includes an insulating spacer, a connecting electrical sheet disposed on the insulating spacer, and a large conductive sheet disposed on the connecting electrical sheet;

[0031] A plurality of small conductive sheets are provided on the side of the upper positioning portion and the side of the lower positioning portion opposite to the large conductive sheet;

[0032] The large conductive sheet and the small conductive sheet can form an electrical connection under the joint action of the pushing device and the conductive cylinder.

[0033] To implement the above technical solution, the insulating spacer is made of insulating material such as nylon to prevent leakage and affect the safety of the equipment. The material of the upper heating plate and the lower heating plate is preferably copper, and the material of the large conductive plate and the small conductive plate is preferably silver. Through the careful layout of the conductive components and the joint action of the pushing device and the conductive cylinder, efficient current transmission is achieved, ensuring the precise control of the heating process, thereby improving the vulcanization quality.

[0034] In one embodiment of the present invention, the support seat is provided with a plurality of asymmetrically arranged positioning blocks, and the centering fixture comprises a centering plate that can be sleeved on the positioning blocks, a centering slide rail arranged in the middle of the centering plate along the front-back direction, a centering slide plate slidably arranged on the centering slide rail, and a centering cylinder driving the centering slide plate to move along the centering slide rail;

[0035] The centering slide plate is provided with two symmetrically arranged waist-shaped holes, and a centering long rod is hinged in the two waist-shaped holes. The ends of the centering long rod are provided with a centering short rod abutting against the stabilizing rod. The centering plate is provided with a positioning sleeve for sleeve-mounting the centering long rod, and an insulating pad is provided at one end of the centering plate close to the centering short rod.

[0036] To implement the above technical solution, during operation, the output shaft of the centering cylinder extends out and causes the centering plate to slide along the centering slide rail. Since waist-shaped holes are symmetrically arranged on both sides of the centering slide plate, the long centering rod will move along the positioning sleeve, and finally the two short centering rods will abut against the two ends of the stabilizer bar, thereby completing the centering positioning of the stabilizer bar and improving the vulcanization accuracy of the bushing. The material of the insulating pad and the short centering plate is preferably nylon, which is a synthetic fiber with good insulation and mechanical properties. The present application ensures the consistency and stability of the vulcanized bushing of the stabilizer bar and improves the qualified rate of the vulcanized bushing press-fitting through the linkage setting of the centering slide plate, the centering slide rail and the centering cylinder.

[0037] In one embodiment of the present invention, the spacing adjustment device includes a bidirectional screw arranged on the base, and two nuts symmetrically screwed on both ends of the bidirectional screw, and the press-fit heating device is arranged on both nuts;

[0038] The base is also provided with a guide rail arranged in parallel with the bidirectional screw rod, and a guide block is slidably provided on the guide rail, and the guide block is fixed at the lower end of the bottom machine seat.

[0039] To implement the above technical solution, the spacing adjustment device facilitates the adjustment of the distance between the two press-fitted heating devices through the cooperation of the bidirectional screw and the nut. The design of the guide rail and the guide block can effectively improve the stability of the press-fitted heating device during movement. During operation, only the hand wheel needs to be manually turned to make the two press-fitted heating devices move closer to or farther away from each other. Therefore, flexible equipment adjustment capability is provided, which facilitates rapid adaptive adjustment according to stabilizer bars of different sizes, improves the versatility and flexibility of the equipment, reduces changeover time, and improves production efficiency.

[0040] In one embodiment of the present invention, the temperature control device comprises:

[0041] Infrared thermometer probe, used to monitor the vulcanization temperature of the bushing in real time;

[0042] A cooling water pipe is arranged on the outer periphery of the lower heating plate;

[0043] The cooling machine connected to the cooling water pipe can adjust the cooling capacity according to the control system instructions and quickly respond to temperature change requirements;

[0044] A heating electric cabinet, wherein a temperature controller is provided in the heating electric cabinet and connected to the connecting electric sheet, and the heating temperature of the bushing is accurately controlled by the temperature controller;

[0045] A control system receives the temperature data of the infrared thermometer probe, and automatically adjusts the cooling capacity of the cooler and the heating temperature of the heating cabinet according to a preset temperature control strategy, so that the vulcanization temperature of the bushing is controlled within a set range.

[0046] To implement the above technical solution, two infrared thermometer probes are used in this application to monitor the two press-fit heating devices separately. For example, after the vulcanization of the bushing on one side is completed, it may be kept warm and pressurized, while the other bushing continues to vulcanize. The temperature control device includes a combination of infrared thermometer probes, cooling water pipes and coolers, as well as intelligent regulation of the heating cabinet and control system, forming a closed-loop temperature control circuit. This design can not only monitor and accurately control the vulcanization temperature in real time, but also respond quickly to temperature changes to ensure that the bushing is vulcanized within the most suitable temperature range, significantly improving product quality and controllability of the production process, and reducing the defective rate.

[0047] In one embodiment of the present invention, the pushing device is a gas-liquid booster cylinder, and the guide assembly includes a guide sleeve arranged on the pushing base, and a guide rod inserted into the guide sleeve and fixed on the pushing plate.

[0048] The above technical solution is realized by using a gas-liquid booster cylinder as a push device, and a guide assembly composed of a guide sleeve and a guide rod, which ensures a smooth and accurate push process, reduces vibration and noise during equipment operation, and improves the stability and service life of the overall equipment. This design not only optimizes the control of the press-fitting force, improves the accuracy and consistency of the press-fitting, but also makes the equipment operation safer and more reliable, which can effectively improve production efficiency and product quality.

[0049] As described above, the integrated press-fitting and heating equipment for vulcanizing bushings of a stabilizer bar of the present invention has the following beneficial effects: the distance between the two press-fitting and heating devices is adjusted by the distance adjusting device, so that it is convenient to vulcanize stabilizer bars of different sizes and specifications; the centering fixture is movably installed on the support seat, so different centering fixtures can be easily replaced according to stabilizer bars of different specifications; during operation, the upper press-fitting and heating component presses the stabilizer bar and the bushing onto the lower press-fitting and heating component, and then the conduction device forms an electrical connection between the upper press-fitting and heating component and the lower press-fitting and heating component, so as to heat the bushing and the stabilizer bar; the present application can adapt to the changing product design requirements and improve the rapid adaptability of the production line to new products;

[0050] The temperature control device can control the temperature of the two press-fitting heating devices separately according to the temperature range set for vulcanization. This design can not only monitor and accurately control the vulcanization temperature in real time, but also respond quickly to temperature changes to ensure that the bushing is vulcanized within the most suitable temperature range, significantly improving product quality and controllability of the production process, and reducing the defective product rate;

[0051] The present application integrates the press-fitting and heating processes of the stabilizer bar bushing, which can be formed in one step, reduces the transfer time between the press-fitting and heating stations, and improves the processing efficiency;

[0052] It can prevent the precision error caused by the shift of the stabilizer bar, ensure the consistency and reliability of product quality, and reduce the factory's floor space, equipment investment cost and operating cost through the integration of press-fitting and heating processes.

During operation, the upper press-fitting heating component presses the stabilizer bar 5 and the bushing 2 onto the lower press-fitting heating component, and then the conduction device forms an electrical connection between the upper press-fitting heating component and the lower press-fitting heating component, thereby heating the bushing 2 and the stabilizer bar 5. The present application integrates the press-fitting and heating processes of the stabilizer bar 5 and the bushing 2, and can be formed in one step, reducing the transfer time at the press-fitting and heating stations, improving the processing efficiency, and preventing the transfer of the stabilizer bar 5 from causing precision errors, thereby ensuring the consistency and reliability of product quality.

The inner lining 11 is made of insulating material to prevent leakage from causing short circuits and causing harm to equipment or human bodies.

[0078] The support seat 4 is provided with a plurality of asymmetrically arranged positioning blocks 29, and the centering fixture includes a centering plate 30 that can be sleeved on the positioning block 29, a centering slide rail 31 arranged in the middle of the centering plate 30 along the front-to-back direction, a centering slide plate 32 slidably arranged on the centering slide rail 31, and a centering cylinder 33 that drives the centering slide plate 32 to move along the centering slide rail 31; the centering slide plate 32 is provided with two symmetrically arranged waist-shaped holes 34, and the two waist-shaped holes 34 are hinged with a centering long rod 35, and the end of the centering long rod 35 is provided with a centering short rod 36 abutting against the stabilizing rod 5, and the centering plate 30 is provided with a positioning sleeve 37 for sleeved on the centering long rod 35, and the centering plate 30 is provided with an insulating pad 38 at one end of the centering plate 30 close to the centering short rod 36.

[0079] During the operation, the output shaft of the centering cylinder 33 extends out and causes the centering plate 30 to slide along the centering slide rail 31. Since waist-shaped holes 34 are symmetrically provided on both sides of the centering slide plate 32, the centering long rod 35 will move along the positioning sleeve 37, and finally the two centering short rods 36 will abut against the two ends of the stabilizer bar 5, thereby completing the centering positioning of the stabilizer bar 5 and improving the vulcanization accuracy of the bushing 2. The material of the insulating pad 38 and the centering short plate is preferably nylon, which is a synthetic fiber with good insulation and mechanical properties. The present application ensures the consistency and stability of the vulcanized bushing 2 of the stabilizer bar 5 through the linkage setting of the centering slide plate 32, the centering slide rail 31 and the centering cylinder 33, and improves the qualified rate of the press-fitting of the vulcanized bushing 2.

[0080] The spacing adjustment device includes a bidirectional screw 39 arranged on the base 1, and two nuts 40 symmetrically screwed on the two ends of the bidirectional screw 39, and the two nuts 40 are provided with the press-fit heating device; the base 1 is also provided with a guide rail 41 arranged parallel to the bidirectional screw 39, and a guide block 42 is slidably provided on the guide rail 41, and the guide block 42 is fixed at the lower end of the base 301.

[0081] The spacing adjustment device facilitates the adjustment of the distance between the two press-fitted heating devices through the cooperation of the bidirectional screw 39 and the nut 40. The design of the guide rail 41 and the guide block 42 can effectively improve the stability of the press-fitted heating device during movement. During operation, only the hand wheel needs to be manually turned to make the two press-fitted heating devices move closer to or farther away from each other. Therefore, flexible equipment adjustment capability is provided, which facilitates rapid adaptive adjustment according to stabilizer bars 5 of different sizes, improves the versatility and flexibility of the equipment, reduces changeover time, and improves production efficiency.

[0082] The temperature control device includes an infrared thermometer probe 43 for real-time monitoring of the vulcanization temperature of the bushing 2; a cooling water pipe 44 arranged on the periphery of the lower heating plate 15; a cooler 45 connected to the cooling water pipe 44, capable of adjusting the cooling capacity according to the control system command and quickly responding to temperature change requirements; a heating electric cabinet 46, wherein a temperature controller is provided in the heating electric cabinet 46 and connected to the connecting electric plate 26, and the heating temperature of the bushing 2 is accurately controlled by the temperature controller; a control system, wherein the control system receives the temperature data of the infrared thermometer probe 43, and according to a preset temperature control strategy, automatically adjusts the cooling capacity of the cooler 45 and the heating temperature of the heating electric cabinet 46, and controls the vulcanization temperature of the bushing 2 within a set range.

[0083] In this application, two infrared thermometer probes 43 are used to monitor the two press-fit heating devices separately. For example, after the vulcanization of the bushing 2 on one side is completed, it may be kept warm and pressurized, while the other bushing 2 continues to vulcanize. The temperature control device includes a combination of an infrared thermometer probe 43, a cooling water pipe 44 and a cooler 45, as well as intelligent regulation of the heating electric cabinet 46 and the control system, forming a closed-loop temperature control circuit. This design can not only monitor and accurately control the vulcanization temperature in real time, but also respond quickly to temperature changes, ensuring that the bushing 2 is vulcanized within the most suitable temperature range, significantly improving product quality and controllability of the production process, and reducing the defective product rate.

[0084] The pushing device 6 is a gas-liquid booster cylinder, and the guide assembly includes a guide sleeve 47 arranged on the pushing base 303, and a guide rod 48 passed through the guide sleeve 47 and fixed on the pushing plate 7.

[0085] By using a gas-liquid booster cylinder as the push device 6, and a guide assembly consisting of a guide sleeve 47 and a guide rod 48, the push process is ensured to be smooth and accurate, the vibration and noise during the operation of the equipment are reduced, and the stability and service life of the overall equipment are improved. This design not only optimizes the control of the press-fitting force, improves the precision and consistency of the press-fitting, but also makes the equipment operation safer and more reliable, which can effectively improve production efficiency and product quality.

[0086] The press-fitting sleeve 13 described in the present invention is movably arranged on the outer lining 12, so different press-fitting sleeves 13 can be replaced according to different specifications of stabilizer bars 5, thereby improving the applicability of the equipment. During operation, the upper heating plate 14 and the lower heating plate 15 transfer heat to the outer lining 12 and further to the press-fitting sleeve 13, thereby completing the heating of the bushing 2 and the stabilizer bar 5. The outer lining 12 and the press-fitting sleeve 13 are preferably made of metal heat-conducting material to reduce the heat energy loss during the vulcanization process of the bushing 2. The inner lining 11 is made of insulating material to prevent leakage from causing short circuits and causing harm to equipment or human bodies. The conduction device is used to complete the electrical conduction between the upper heating plate 14 and the lower heating plate 15. The specific working process is to conduct electricity on one of the conduction devices and then complete the electrical connection of the lower heating plate 15, the other conduction device, and the upper heating plate 14 in turn, thereby ensuring the thermal efficiency of the vulcanized bushing 2 and promoting the thermal uniformity of the vulcanization process.

[0087] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
