Description

Technical Field

[0001] This application relates to the technical field of riveting tooling molds, and in particular to an induction pressing steel sleeve tooling. Background Technology

[0002] The wheel hub is the part of the car where the axle is mounted at the center of the wheel; it's commonly referred to as the wheel rim or rim. Bolts are typically installed on the wheel hub, and to ensure the tire is stably mounted on the axle, thus supporting the weight of the entire vehicle and cushioning external impacts, a steel sleeve is usually riveted to the bolt mounting point on the wheel hub. The bolt is then secured to the wheel hub through the steel sleeve.

[0003] After the steel sleeve is riveted onto the wheel hub, it is necessary to measure the firmness of the connection between the steel sleeve and the wheel hub. This is usually done manually using a plug gauge. However, manual inspection using a plug gauge is cumbersome, time-consuming, and labor-intensive. Furthermore, the wheel hub and steel sleeve may become loose after inspection, causing the product to be scrapped. This problem urgently needs to be solved. Utility Model Content

[0004] To facilitate the measurement of the connection strength between the steel sleeve and the wheel hub, and to prevent the product from being scrapped due to testing, this application provides an inductive pressure steel sleeve tooling.

[0005] This application provides an induction pressing steel sleeve tooling, which adopts the following technical solution:

[0006] An inductive steel pressing sleeve fixture is mounted on a hydraulic cylinder. The fixture includes an upper template and a lower template that cooperate with each other. The hydraulic cylinder drives the upper template to move towards or away from the lower template. A support seat is provided on the surface of the lower template facing the upper template, and a positioning post is provided on the support seat. A pressure cylinder is correspondingly provided on the surface of the upper template facing the lower template. The pressure cylinder is movably sleeved on the positioning post. A pressure sensor is provided between the pressure cylinder and the upper template. The pressure sensor is connected to a control system. The control system is electrically connected to both the pressure sensor and the hydraulic cylinder.

[0007] By adopting the above technical solution, the workers first place the wheel hub and steel sleeve on the support base, which supports the wheel hub and steel sleeve. At the same time, the wheel hub and steel sleeve are fitted onto the positioning post, which positions the wheel hub and steel sleeve. Then, the hydraulic cylinder drives the upper template to move closer to the lower template. The upper template drives the pressure cylinder to move on the positioning post to rivet the steel sleeve and wheel hub together. During this process, the pressure sensor senses the pressure on the pressure cylinder and feeds the pressure data back to the control system. The control system sends an electrical signal to the hydraulic cylinder based on the pressure data to adjust the thrust of the hydraulic cylinder on the pressure cylinder. The connection between the steel sleeve and the wheel hub is measured during the pressing process, eliminating the need for subsequent inspection operations, saving time and effort, and preventing the product from being scrapped due to inspection.

[0008] Preferably, the control system has a human-machine interface.

[0009] By adopting the above technical solutions, the human-computer interaction interface can be adjusted and set according to actual needs, making it convenient and quick.

[0010] Preferably, the control system has pre-stored pressure upper and lower limit data.

[0011] By adopting the above technical solution, it is possible to detect whether the pressing pressure is within the predetermined range, which is convenient, quick, and easy to understand.

[0012] Preferably, the number of positioning posts is set to a plurality of them, which are arranged in a ring and adapted to the position where the steel sleeve needs to be installed on the wheel hub. The number of pressure cylinders and pressure sensors is the same as the number of positioning posts, and one pressure sensor corresponds to one pressure cylinder.

[0013] By adopting the above technical solution, the number of positioning pins, pressure cylinders and pressure sensors is set according to the number of steel sleeves to be installed on the wheel hub. All steel sleeves on a wheel hub can be installed at one time, which helps to improve work efficiency and allows for the detection of the pressing pressure between each steel sleeve and the wheel hub.

[0014] Preferably, each pressure sensor is provided with a different marking section, and the control system is provided with a number of data storage units corresponding to the pressure sensors with different marking sections.

[0015] By adopting the above technical solution, the pressure data of the induction pressure steel sleeve tooling has output, input and storage functions. The control system sets up several data storage units for pressure sensors with different markings, which makes it easy to quickly find the pressure data of the corresponding pressure sensor according to the markings of the data storage unit.

[0016] Preferably, the control system is connected to an alarm system. When the pressure data detected by the pressure sensor is not between the upper and lower pressure limits stored in the control system, the control system sends an electrical signal to the alarm system.

[0017] By adopting the above technical solution, when the pressure data detected by the pressure sensor is not between the upper and lower pressure limits stored in the control system, it proves that there is an abnormality in the pressing process. At this time, the control system sends an electrical signal to the alarm system to remind the staff to handle the problem. This is convenient, quick, and timely.

[0018] Preferably, the pressure sensor is arranged in the shape of a circular plate, and the pressure sensor is attached to the upper end of the pressure cylinder and coaxial with the pressure cylinder.

[0019] By adopting the above technical solution, this setting helps to improve the sensing accuracy of the pressure sensor.

[0020] Preferably, the upper end of the positioning post is pointed.

[0021] By adopting the above technical solution, this setting makes it easier for workers to put the wheel hub and steel sleeve on the positioning post, and also makes it easier for the pressure cylinder to be put on the positioning post during the pressing process.

[0022] Preferably, the positioning post is detachably connected to the support base.

[0023] By adopting the above technical solution, the positioning post can be detachably connected to the support base, making the positioning post replaceable and thus adaptable to the pressing operation of wheel hubs and steel sleeves of different specifications and sizes, with strong applicability.

[0024] Preferably, the support base is provided with a fixing member for fixing the positioning column.

[0025] By adopting the above technical solution, when the positioning column is connected to the support base, the fixing component will fix the positioning column to the support base, which is conducive to improving the stability of the connection between the positioning column and the support base, thereby improving the stability of the pressing process and thus improving the pressing quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a pressure sensor and control system, during the pressing process of the wheel hub and steel sleeve, the pressure sensor senses the pressure on the pressure cylinder and feeds the pressure data back to the control system. The control system sends an electrical signal to the hydraulic cylinder according to the pressure data to adjust the thrust of the hydraulic cylinder on the pressure cylinder. During the pressing process, the connection between the steel sleeve and the wheel hub is measured, eliminating the need for subsequent inspection operations, saving time and effort, and preventing the product from being scrapped due to inspection.

[0028] 2. By pre-storing the upper and lower pressure limit data in the control system, it is possible to detect whether the press-fitting pressure is within the predetermined range, which is convenient, quick, and easy to understand.

[0029] 3. By setting different markings on each pressure sensor and setting different data storage units for pressure sensors with different markings in the control system, the pressure data of the inductive pressure sleeve tooling has output, input and storage functions. The control system sets several data storage units for pressure sensors with different markings, which makes it easy to quickly find the pressure data of the corresponding pressure sensor according to the markings of the data storage units.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an inductive pressure steel sleeve tooling, referring to... Figure 1 and Figure 2 This device is mounted on a hydraulic cylinder (not shown in the figure), which provides power to the induction pressing steel sleeve tooling. Specifically, the induction pressing steel sleeve tooling includes an upper template 1 and a lower template 2 that cooperate with each other. The lower template 2 is horizontally fixed to the bottom of the hydraulic cylinder, and the upper template 1 is horizontally fixed to the drive rod of the hydraulic cylinder, with the upper template 1 located directly above the lower template 2. The hydraulic cylinder drives the upper template 1 to move vertically up and down in the direction of approaching or moving away from the lower template 2 to provide power for the pressing steel sleeve operation.

[0038] Reference Figure 1 and Figure 2A support base 3 is fixedly installed on the surface of the lower template 2 facing the upper template 1. The support base 3 supports the wheel hub and steel sleeve. A positioning post 4 is vertically installed on the support base 3, limiting the position of the wheel hub and steel sleeve on the support base 3 to improve the accuracy of pressing. Correspondingly, a pressure cylinder 5 is vertically installed on the surface of the upper template 1 facing the lower template 2. The pressure cylinder 5 is located directly above and aligned with the positioning post 4, allowing it to be movably fitted onto the positioning post 4. When pressing the wheel hub and steel sleeve together, the operator first places the wheel hub on the support base 3, then places the steel sleeve at the position where the bolts need to be tightened. The positioning post 4 passes through the wheel hub and steel sleeve to position them. Then, the hydraulic cylinder drives the pressure cylinder 5 vertically downwards through the upper template 1, allowing the pressure cylinder 5 to fit onto the positioning post 4 and press the steel sleeve and wheel hub together tightly.

[0039] Reference Figure 1 and Figure 2 The upper end of the positioning post 4 is pointed to facilitate the worker in placing the wheel hub and steel sleeve onto the positioning post 4, and also to facilitate the placement of the pressure cylinder 5 onto the positioning post 4 during the pressing process. It should be noted that the positioning post 4 is detachably connected to the support base 3. In this embodiment, the positioning post 4 is detachably connected to the support base 3 by means of a threaded connection. At the same time, in order to improve the stability of the positioning post 4 connected to the support base 3, the support base 3 is also provided with a fixing member for fixing the positioning post 4. In this embodiment, the fixing member is a clamping bolt 7. After the positioning post 4 bolt is inserted into the support base 3, the clamping bolt 7 is threaded into the support base 3 from the side wall of the support base 3 and abuts against the side wall of the positioning post 4.

[0040] Reference Figure 1 and Figure 2 The support base 3 is connected to a number of positioning pins 4. In this embodiment, the number of positioning pins 4 is set to five. The five positioning pins 4 are arranged in a circle and are adapted to the position where the steel sleeves need to be installed on the wheel hub. The number of pressure cylinders 5 is the same as the number of positioning pins 4, which is five, so that all the steel sleeves on a wheel hub can be pressed in one go, thereby improving work efficiency.

[0041] Reference Figure 1 and Figure 3Each pressure cylinder 5 and the upper template 1 is equipped with a pressure sensor 6, with each pressure sensor 6 corresponding to the pressure data of one pressure cylinder 5. Simultaneously, the pressure sensor 6 is connected to a control system (not shown in the figure), and the control system is electrically connected to the pressure sensor 6 and the hydraulic cylinder. The pressure sensor 6 detects the pressure during the pressing process and feeds the pressure data back to the control system. The control system sends an electrical signal to the hydraulic cylinder based on the pressure data to adjust the thrust of the hydraulic cylinder. During the pressing process, the connection strength between the steel sleeve and the hub is measured, eliminating the need for subsequent inspection operations, saving time and labor, and preventing product scrapping due to inspection.

[0042] Reference Figure 3 and Figure 4 The pressure sensor 6 is arranged in a circular plate shape. Its upper surface is fixed to the lower plate of the upper template 1, and its lower surface is attached to the upper end of the pressure cylinder 5 and coaxially arranged with it to improve the accuracy of pressure sensing. In addition, the control system has a human-machine interface, allowing operators to easily and quickly adjust settings according to actual needs. The control system also stores upper and lower pressure limit data to detect whether the pressing pressure is within the predetermined range. Furthermore, each pressure sensor 6 has a different marking section, and the control system has five data storage units corresponding to the pressure sensors 6 with different marking sections. This allows for the output, input, and storage of pressure data from the sensing steel sleeve tooling, and facilitates quick retrieval of pressure data from the corresponding pressure sensor 6 based on the marking section of the data storage unit.

[0043] Reference Figure 3 and Figure 4 The control system is also connected to an alarm system (not shown in the figure). When the pressure data detected by the pressure sensor 6 after the hydraulic cylinder thrust adjustment is still not between the upper and lower pressure limits preset by the control system, it indicates that an abnormality has occurred in the pressing process. The control system sends an electrical signal to the alarm system to remind the staff to handle the situation, which is convenient, quick, and timely. It is worth mentioning that if the pressure data fed back by the pressure sensor 6 does not change during operation, it indicates that the steel sleeve has been misplaced, allowing the staff to react quickly.

[0044] The implementation principle of the inductive pressing steel sleeve tooling in this application embodiment is as follows: During the pressing process of the steel sleeve and the wheel hub, the operator first places the wheel hub and the steel sleeve on the support base 3. The positioning column 4 positions the wheel hub and the steel sleeve. Then, the hydraulic cylinder drives the upper template 1 to move the pressing cylinder 5 onto the positioning column 4 and presses the steel sleeve and the wheel hub so that the steel sleeve is fixed at the position where the wheel hub needs to install bolts. During the pressing process, the pressure sensor 6 senses the pressure on the pressing cylinder 5 and feeds the pressure data back to the control system. The control system sends an electrical signal to the hydraulic cylinder according to the pressure data to adjust the thrust of the hydraulic cylinder on the pressing cylinder 5. During the pressing process, the connection firmness between the steel sleeve and the wheel hub is measured. No subsequent inspection operation is required, which saves time and effort and prevents the product from being scrapped due to inspection.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
