Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a bearing housing end face leveling fixture. Background Technology

[0002] In the field of machining, machining fixtures are crucial devices for fixing workpieces and ensuring machining accuracy; their performance directly affects the machining quality and efficiency. For end-face machining of components such as bearing housings, traditional leveling fixtures typically employ rigid supports or manual adjustments, which have significant technical drawbacks: Firstly, traditional fixtures rely on operator experience for visual leveling, failing to accurately quantify the height differences between points on the bearing housing end face, leading to large errors in cutting quantity calculations. This often results in material waste due to over-cutting or affects subsequent assembly accuracy due to insufficient leveling precision. Secondly, existing fixtures mostly employ fixed structures, making it difficult to flexibly adjust support points according to the actual shape of the bearing housing blank. Furthermore, insufficient clamping stability leads to displacement during machining, requiring repeated clamping and adjustments, significantly reducing production efficiency. In addition, traditional fixtures lack efficient height measurement and feedback mechanisms, making it impossible to quickly determine the optimal cutting quantity, resulting in prolonged machining time and high costs.

[0003] The bearing seat end face leveling fixture proposed in this utility model effectively solves the problems of low leveling accuracy, poor material utilization, and low processing efficiency in the prior art through electromagnetic adsorption, elastic measuring rod measurement, and precise drive structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a bearing housing end face leveling fixture to address these issues.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A bearing housing end face leveling fixture includes an electromagnet, which is fixedly mounted on the table of a machine tool. Clamping components are fixedly mounted at both ends of the electromagnet. A spacer and an ejector seat are respectively adsorbed on the top surface of the electromagnet. Several ejector seats are provided, and a measuring rod is fixedly connected to the top of each ejector seat. The measuring rod passes through the spacer and abuts against the bottom surface of the bearing housing. A spring is sleeved on the outer side of the measuring rod, and a spacer is fixedly connected to the top of the spring. The spacer is sleeved on the outside of the measuring rod and fixedly connected to it. The bottom surface of the spring abuts against the top surface of the spacer. The measuring rod, in cooperation with the spacer, is used to measure the height of the ejected measuring rod.

[0008] Preferably, the clamping member includes a fixed base, a support plate is fixedly connected to the top surface of the fixed base, and a plurality of screws are screwed to the side of the support plate, the screws abutting against the side of the bearing seat.

[0009] Preferably, the partition includes a partition plate and several legs. The top surface of the partition plate has several through holes, and the measuring rod passes through one of the through holes and slides in contact with the through hole. The partition plate is arranged parallel to the top surface of the magnetic disk. The bottom edge of the partition plate is fixedly connected to the top end of each leg, and the bottom end of each leg is detachably connected to the magnetic disk.

[0010] Preferably, the measuring rod has a scale bar on its side for marking length.

[0014] Compared with the prior art, the present invention has the following advantages and technical effects:

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0024] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Depend on Figure 1-4The bearing housing end face leveling fixture shown includes an electromagnet 1, also known as an electro-permanent magnet chuck, which is a device that generates basic attraction through a permanent magnet and controls the magnetic force using an excitation coil. Its working principle is based on the superposition effect of electromagnetic and permanent magnetic fields. The attraction force is switched by changing the direction of the coil current, with a switching time of less than 1 second, and no continuous power supply is required during operation. This is existing technology and will not be described in detail here. The electromagnet 1 is fixedly installed on the table of a machining tool. Clamping components are fixedly installed at both ends of the electromagnet 1. A spacer and ejector seats are respectively attracted to the top surface of the electromagnet 1. Several ejector seats are provided, and a measuring rod 2 is fixedly connected to the top of each ejector seat. The measuring rod 2 passes through the spacer and abuts against the bottom surface of the bearing housing 3. A spring 4 is sleeved on the outer side of the measuring rod 2, and a spacer 5 is fixedly connected to the top of the spring 4. The spacer 5 is sleeved on the outside of the measuring rod 2 and fixedly connected to the measuring rod 2. The bottom surface of the spring 4 abuts against the top surface of the spacer. The measuring rod 2, in conjunction with the spacer, is used to measure the height of the ejected measuring rod 2.

[0026] Furthermore, the spring 4 can support the measuring rod 2 by cooperating with the spacer 5, and can also pull the measuring rod 2 back by the drive of the ejector seat, so that the measuring rod 2 is in stable contact with the ejector seat.

[0027] Further optimizing the design, the ejector base includes two fixed plates 6, with a sliding plate 7 fixedly connected between them. A telescopic component 8 is fixedly connected to one end of the top surface of the sliding plate 7, and a driving block 9 is fixedly connected to one end of the telescopic component 8. The driving block 9 is connected to an ejector block 10, whose top surface is fixedly connected to the bottom surface of the measuring rod 2. The ejector block 10 slides in contact with both fixed plates 6. Furthermore, a limiting block 18 is abutting against the bottom surface of the ejector block 10. The limiting block 18 is fixedly connected to both fixed plates 6, and the top surfaces of any two limiting blocks 18 are parallel to and at the same height as the top surface of the electromagnet 1. By setting the limiting blocks 18, the measuring rod 2 can be kept at the same height, facilitating the operator to adjust the ejection height of the measuring rod 2 and calculate the cutting amount.

[0028] Furthermore, the telescopic component 8 preferably uses an electric cylinder, which has high repeatability, typically between 0.01-0.02 mm, which is beneficial for the high-precision drive of the telescopic drive block 9 to push up the measuring rod 2 via the push-out block 10.

[0029] Furthermore, the fixing plate 6 and the sliding plate 7 are made of ferrous metal, which facilitates magnetic connection with the electric disk 1, enabling flexible adjustment of the ejector seat on the electric disk 1.

[0030] The design is further optimized. The clamping component includes a fixed base 11, which is fixedly connected to the table surface by bolts. A support plate 12 is fixedly connected to the top surface of the fixed base 11, and several screws 13 are screwed to the side of the support plate 12. The screws 13 abut against the side of the bearing seat 3. The rotation of the screws 13 abuts against the bearing seat 3, and the bearing seat 3 is stably fixed by clamping it from both sides. To improve the clamping stability of the bearing seat 3, a push plate 19 is fixedly connected to one end of the screws 13. One side of the push plate 19 abuts against the side of the bearing seat 3. A grid groove 20 is opened on the side of the push plate 19 near the bearing seat 3. The push plate 19 increases the clamping area of ​​the bearing seat 3, and the grid groove 20 improves the clamping friction between the push plate 19 and the bearing seat 3.

[0031] The design is further optimized. The partition includes a partition plate 14 and several support legs 15. The top surface of the partition plate 14 has several through holes 16. The measuring rod 2 passes through one of the through holes 16 and slides in contact with the through hole 16. The partition plate 14 is arranged parallel to the top surface of the electromagnet 1. The bottom edge of the partition plate 14 is fixedly connected to the top of the support legs 15, and the bottom end of the support legs 15 is detachably connected to the electromagnet 1. The presence of several through holes 16 facilitates the adjustment of the position of the measuring rod 2 and improves the convenience of ejecting the bearing seat 3.

[0032] To further optimize the design, a scale bar 17 for marking length is provided on the side of the measuring rod 2. By using the connection between the measuring rod 2 and the top surface of the partition 14 as the reading line of the scale bar 17, the lifting height of the measuring rod 2 can be quantified.

[0033] In a further optimized design, the driving surfaces of the ejector block 10 and the drive block 9 are inclined planes, each with mutually sliding and adaptable teeth 21 and slots 22. The tooth crests of the teeth 21 are tilted away from the drive block 9. Through the cooperation of the teeth 21 and the different slots 22, the drive block 9 can continuously drive the ejector block 10 to rise, and the problem of the ejector block 10 reversing and driving the drive block 9 back due to excessive load can be prevented.

[0034] Furthermore, the lateral spacing between two adjacent inserts 21 is preferably set to 0.2mm-1mm, which, in conjunction with the telescopic component 8, enables precise lifting and lowering of the measuring rod 2.

[0035] The working process of this embodiment is as follows:

[0036] First, visually inspect the end face of the blank bearing housing 3 and select several support points to facilitate the placement of the measuring rod 2 to support the bearing housing 3. Based on the position of the measuring rod 2, the position of the ejector seat can be determined, and it is magnetically held in place along with the spacer using the electromagnet 1. Using the reading of the measuring rod 2 at the lowest point of the bearing housing 3's end face as the base zero point, and the values ​​of the readings of the other measuring rods 2 after visually leveling the bearing housing 3 as the database, subtract the value of the lowest measuring rod 2 from each value to obtain the maximum value T. T quantifies the cutting amount. To maximize the use of the material of the bearing housing 3, a cutting amount of T / 2 can be selected to mill the end face of the bearing housing 3. Then, using the milled end face as the reference surface, mill the other end face of the bearing housing 3 again. This completes the leveling of the end face of the bearing housing 3.

[0037] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
