Description

Technical Field

[0001] The utility model relates to the technical field of transmission shaft processing, in particular to a device for improving the processing efficiency of a transmission shaft. Background Art

[0002] The drive shaft processing device is a mechanical equipment used to process the drive shaft. It is usually composed of machine tools, fixtures, cutting tools and control systems. The drive shaft is an important component connecting the engine and the transmission. Its processing accuracy directly affects the performance and reliability of the car. Therefore, the drive shaft processing device needs to have the characteristics of high precision, high efficiency and high stability.

[0003] The processing of the transmission shaft processing device usually includes turning, grinding, rolling and stretching. During the processing, high-precision machine tools and cutting tools are required to ensure the dimensional accuracy and surface quality of the transmission shaft. At the same time, in order to ensure the stability and reliability of the processing, professional fixtures and testing equipment are required to accurately position and measure the transmission shaft.

[0004] The control system of the transmission shaft processing device is also a very important component. It needs to realize automatic control and monitoring of the processing process to ensure the stability and accuracy of the processing. At the same time, it is also necessary to monitor and record various parameters in the processing process in real time for quality analysis and traceability. The transmission shaft processing device is a very important mechanical equipment. It can effectively improve the processing accuracy and efficiency of the transmission shaft and provide high-quality transmission shaft parts for the automotive manufacturing industry.

[0005] The existing transmission shaft processing efficiency improvement device generally clamps the middle section of the transmission shaft for the existing processing device, and does not have the function of clamping the transmission shaft in multiple ways. For example, a transmission shaft processing device disclosed in the authorized Chinese patent CN220113143U can be used in combination with structures such as a base, a transmission shaft body, an auxiliary component, a connecting plate 1, a guide rail 1, a moving seat 1, a screw rod 1, a ball nut 1, a motor 1, a connecting plate 2, a guide rail 2, a moving seat 2, a screw rod 2, a ball nut 2, a motor 2, an adjustment bin, an arc guide rail, an arc sleeve, a support plate, a rack, a worm, a motor 3, a pneumatic telescopic rod, a clamp, a clamp and a hand-tightening bolt to make the transmission shaft processing process more flexible, and can select the clamping position according to the section to be processed of the transmission shaft. At the same time, the device can adjust the transmission shaft X, Z, and Y axes, and can also adjust the pitch angle of the transmission shaft to achieve the effect of quickly centering the transmission shaft.

[0006] However, the transmission shaft processing efficiency improvement device in the above-mentioned cited document can complete a milling key with one clamping when in use, while the traditional processing method requires multiple clampings, and each clamping requires calibration of the workpiece position and centering, which is time-consuming and labor-intensive. Frequent clamping requires shutdown operations in the middle, resulting in low processing efficiency. Since the CNC system of the machining center can only control the movement of the tool along the trajectory but cannot control the positioning of the workpiece, the workpiece needs to be fixed on the machining center platform through clamping before milling processing can be performed, resulting in the use effect of the existing transmission shaft processing device to be improved.

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-4 The utility model provides a technical solution: a transmission shaft processing efficiency improvement device, comprising a clamping plate 1, a connecting block 2 and a magnet 4, one side of the connecting block 2 is fixedly mounted on the side of the clamping plate 1 close to the ground, and the magnet 4 is fixedly mounted on the side of the connecting block 2 close to the ground; a processing efficiency improvement mechanism 300 is installed on the side of the clamping plate 1 away from the connecting block 2;

[0032] Through the mutual cooperation between the connecting block 2 on the clamping plate 1, the processing efficiency improving mechanism 300 and the magnet 4, twenty workpieces can be clamped at one time, which not only improves the processing efficiency, but also reduces the clamping error, reduces the labor intensity of workers, improves work efficiency and work quality, and also improves the processing accuracy. In addition, the processing stability can be improved by magnetic attraction, avoiding the problem of deviation caused by the operator's technical level and different attention, thereby improving the processing quality, thereby effectively improving the use effect of the existing transmission shaft processing device.

[0033] It should be noted that the number of magnets 4 is multiple and evenly distributed so as to be able to magnetically attract the entire fixture with the drive shaft installed on the work surface.

[0034] In this embodiment, the machining efficiency improvement mechanism 300 is a structure that can clamp twenty workpieces at one time.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the processing efficiency improvement mechanism 300 includes two clamps 301 fixedly connected to the side of the clamping plate 1 away from the connecting block 2;

[0036] The clamp 301 is provided with slots 302 arranged at equal distances on one side away from the connection block 2;

[0037] The processing efficiency improvement mechanism 300 also includes a bolt hole 303, a transmission shaft 304, a pressure plate 305 and a fixing bolt 306; the outer side of the transmission shaft 304 is clamped on the inner side of the slot 302, and two bolt holes 303 in mirror symmetry are opened on one side of the clamp 301 between the opposite sides of each two transmission shafts 304, and the side between each two transmission shafts 304 away from the clamp 1 is abutted against one side of the pressure plate 305, and the fixing bolt 306 passes through one side of the pressure plate 305 and is threadedly connected to the inner side of the bolt hole 303. The function of the fixing bolt 306 is to tightly abut the transmission shaft 304 and the clamp 1 together to prevent relative movement, thereby ensuring the stability and reliability of the transmission shaft 304. At the same time, the function of the pressure plate 305 is to strengthen the connection between the fixing bolt 306 and the transmission shaft 304, thereby improving the strength and stability of the entire structure.

[0038] It should be noted that the two clamps 301 are distributed in mirror symmetry to achieve a symmetrical clamping effect and improve the clamping accuracy and stability.

[0039] It can be understood that the projection of the pressure plate 305 in the first direction is a rectangle with a length of L. The first direction is parallel to the axial direction of the fixing bolt 306. The distance between the two corresponding opposite sides of the transmission shafts 304 is D. L>D is to ensure that the projection length of the pressure plate 305 in the first direction is greater than the distance between the two transmission shafts 304, thereby ensuring that the transmission shaft 304 can be stably fixed and clamped.

[0040] In addition, the projection of the slot 302 in the second direction is a circle with a diameter of C. The second direction is parallel to the axial direction of the transmission shaft 304. The outer diameter of the transmission shaft 304 is Q, and C=Q, so as to ensure that the transmission shaft 304 can be snugly connected in the slot 302.

[0041] It should also be noted that there are multiple magnets 4 that are evenly distributed and are used for magnetic connection with the processing platform.

[0042] The working principle of the above embodiment is:

[0043] Install the transmission shaft 304 on the slot 302 of the fixture 301 in groups of two, and pass through the pressure plate 305 through the fixing bolts 306 to be threaded into the bolt hole 303 and tightened. Under the thrust of the thread rotation, the pressure plate 305 and the transmission shaft 304 are tightly abutted to fix them in place. The clamping plate 1 with the installed transmission shaft 304 is magnetically attracted to the workbench through the magnet 4 on the connecting block 2. Then adjust the tool and start the keyway processing. Complete the keyway processing of 20 pieces in one pass, check the processing quality, if there are defective products, perform trimming or re-cutting, and the processing is completed. Finally, disassemble the fixture for quality inspection and packaging.

[0044] Compared with the prior art: the transmission shaft processing efficiency improvement device, through the mutual cooperation between the connecting block 2 on the clamping plate 1, the processing efficiency improvement mechanism 300 and the magnet 4, can clamp twenty workpieces at one time, which not only improves the processing efficiency, but also reduces the clamping error, reduces the labor intensity of workers, improves work efficiency and work quality, and also improves the processing accuracy. In addition, the processing stability can be improved by magnetic attraction, avoiding the problem of deviation caused by the operator's technical level and different attention, thereby improving the processing quality, thereby effectively improving the use effect of the existing transmission shaft processing device, and solving the problem of poor use effect of the existing transmission shaft processing device.

[0045] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
