DETAILED DESCRIPTION

[0023] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a processing device for a frame, comprising: The mounting seat 100 is provided with a first driving member 102, a second driving member 104 and a spline shaft 106. The first driving member 102 is in transmission connection with the spline shaft 106 to drive the spline shaft 106 to move along the axial direction of the spline shaft 106; A reduction assembly is transmission-connected between the second driving member 104 and the spline shaft 106, and the second driving member 104 drives the spline shaft 106 to rotate along the circumferential direction of the spline shaft 106 through the reduction assembly; The machining sleeve 108 is used to install the tool and is sleeved on the end of the spline shaft 106 through a bearing assembly. The spline shaft 106 drives the machining sleeve 108 to move synchronously along the axial and circumferential directions of the spline shaft 106 through the bearing assembly.

[0025] According to the processing device for the frame provided by the embodiment of the present invention, since the spline shaft 106 can move in the axial direction and the circumferential direction at the same time, and these movements are realized by a high-precision transmission mechanism, the processing accuracy can be greatly improved. This is particularly important for processing tasks that require precise control of the tool motion trajectory. By adjusting the output parameters (such as rotation speed, torque, etc.) of the first drive member 102 and the second drive member 104, the movement mode and speed of the spline shaft 106 can be flexibly controlled. This enables the processing device to adapt to different types of frame processing requirements and improves the versatility and flexibility of the equipment. Since the processing sleeve 108 and the spline shaft 106 are stably connected and synchronously moved by the bearing assembly, the operator only needs to control the output of the first drive member 102 and the second drive member 104 to realize complex processing operations. This greatly simplifies the processing operation process for the frame and reduces the difficulty and labor intensity of the operation. Since the processing device can realize high-precision processing operations and the operation process is relatively simple, the production efficiency of the frame can be greatly improved. At the same time, since the equipment has high versatility and flexibility, it can adapt to different types of processing tasks, further improving the utilization rate and production efficiency of the equipment.

[0026] Please continue to see Figures 1 to 5 The mounting base 100 serves as the basic supporting structure of the entire processing device, and multiple key components are integrated on the mounting base 100.

[0027] Specifically, the mounting seat 100 is provided with a first driving member 102, a second driving member 104 and a spline shaft 106. The first driving member 102 and the spline shaft 106 are connected to each other through a transmission mechanism (such as a gear, a chain or a belt, etc.), so that the first driving member 102 can drive the spline shaft 106 to move linearly along its axial direction.

[0028] The reduction assembly is located between the second drive member 104 and the spline shaft 106, and plays a role in reducing the rotation speed and increasing the torque. The second drive member 104 transmits power to the spline shaft 106 through the reduction assembly, thereby driving the spline shaft 106 to rotate along its circumference. The introduction of the reduction assembly makes the rotation speed of the spline shaft 106 more controllable, which helps to achieve more sophisticated processing operations.

[0029] The machining sleeve 108 is a key component for installing the tool. The machining sleeve 108 is sleeved on the end of the spline shaft 106 through the bearing assembly, and maintains a relatively fixed position relationship with the spline shaft 106. Due to the presence of the bearing assembly, the machining sleeve 108 can be driven by the spline shaft 106 to perform synchronous movements in the axial direction and the circumferential direction at the same time. In this way, the tool installed on the machining sleeve 108 can perform machining operations according to a predetermined trajectory.

[0030] According to one embodiment of the present invention, the bearing assembly comprises: The bearing inner ring 110 is sleeved on the spline shaft 106 and has a slide groove 112 on the bearing inner ring 110. The friction coefficient of the slide groove 112 is different from the friction coefficient of the inner wall of the processed sleeve 108. The ball bearing 114 is embedded in the slide groove 112 and abuts against the inner wall of the processing sleeve 108 and the slide groove 112 .

[0031] In one embodiment of the present invention, the inner ring 110 of the bearing is one of the core components of the assembly and is designed to be sleeved on the spline shaft 106. This design ensures that the bearing assembly can be firmly fixed on the transmission system. In particular, a series of slide grooves 112 are provided on the inner ring 110 of the bearing. These slide grooves 112 are not only used to accommodate the balls 114, but also through specific materials and surface treatment processes, the friction coefficient of the slide groove 112 is significantly different from the friction coefficient of the inner wall of the processed sleeve 108. This design helps to optimize the rolling behavior of the balls 114 in the slide groove 112 and reduce unnecessary friction and wear. More importantly, since the friction coefficient of the slide groove 112 is significantly different from the friction coefficient of the inner wall of the processed sleeve 108, the balls 114 can rotate along the circumference of the spline shaft 106, and at the same time, the balls 114 can also rotate along the axial tangential direction of the spline shaft 106.

[0032] For example, the friction between the ball 114 and the slide groove 112 is that between steel and nylon, and the friction coefficient is 0.07; the friction between the steel ball and the inner wall of the processed sleeve 108 is that between steel and bearing alloy, and the friction coefficient is 0.2. Since the friction coefficients of the two are very different, under the action of the friction force generated between the ball 114 and the inner wall of the processed sleeve 108 and the friction force generated between the ball 114 and the inner ring 110 of the bearing, the ball 114 will rotate circumferentially along the spline shaft 106. The other movement direction of the ball 114 is rotational motion along the axial tangent direction, realizing a linear and rotational composite rolling motion.

[0033] The balls 114 are precisely embedded in the grooves 112 of the inner ring 110 of the bearing. Their main function is to act as a transmission medium, forming rolling contact between the inner ring 110 of the bearing and the inner wall of the processed sleeve 108, thereby significantly reducing the friction resistance during movement. By accurately designing the friction coefficient of the groove 112 and the rolling contact of the balls 114, the bearing assembly of the present invention can significantly reduce the friction resistance during transmission. This not only helps to reduce energy loss and improve transmission efficiency, but also prolongs the service life of the assembly. The precise rolling of the balls 114 in the grooves 112 ensures the stability and accuracy of the bearing assembly at high speeds. This is particularly important for transmission systems that require high-precision positioning. By reasonably designing the number and size of the balls 114, the bearing assembly of the present invention can withstand greater axial and radial loads. This makes it particularly suitable for heavy-load and high-speed transmission applications. The modular design of the bearing assembly makes its maintenance and replacement simpler and faster. This reduces downtime and maintenance costs and improves the overall operating efficiency of the equipment.

[0034] In the embodiment of the present invention, through the cooperation between the slide groove 112, the ball 114, the ball 114, the slide groove 112 and the processed sleeve 108, the axial motion delay accuracy is <0.01 mm, and the bearing installation pre-tightening can be performed to improve the radial runout accuracy to more than 0.005 mm.

[0035] According to an embodiment of the present invention, the processing device further comprises a tool locking sleeve 116 , which is sleeved on the spline shaft 106 and is located at one end of the bearing inner ring 110 facing the processing sleeve 108 .

[0036] In one embodiment of the present invention, the processing device further includes a tool locking sleeve 116. The tool locking sleeve 116 is designed to be sleeved on the spline shaft 106 and is located at one end of the bearing inner ring 110 facing the processing sleeve 108. This design is intended to ensure that the tool can remain stable during installation and operation, and prevent the tool from loosening or falling off due to vibration or external force.

[0037] Specifically, the tool locking sleeve 116 achieves a secure locking of the tool through its unique structure and material selection. It may use threaded connection, snap connection or other reliable connection methods to ensure a tight fit with the spline shaft 106 and the processing sleeve 108. In addition, the tool locking sleeve 116 may also have an adjustment function, allowing the operator to adjust the tightening degree of the tool within a certain range to adapt to different processing requirements and tool specifications.

[0038] The tool locking sleeve 116 can ensure the stability of the tool during installation and operation, thereby reducing processing errors caused by loosening or falling off of the tool. This helps to improve processing accuracy and product quality. By firmly locking the tool, the tool locking sleeve 116 reduces the vibration and impact of the tool during processing, thereby extending the service life of the tool. Since the tool locking sleeve 116 can ensure the stable operation of the tool, the downtime and maintenance costs caused by tool problems are reduced. This helps to improve production efficiency and equipment utilization. The design of the tool locking sleeve 116 makes the installation and removal of the tool easier and faster, reducing the difficulty of operation and labor intensity.

[0039] According to one embodiment of the present invention, a tool mounting section 118 is provided on the spline shaft 106, and a tool locking sleeve 116 is sleeved on the tool mounting section 118. A tool mounting hole 120 is opened at the end of the tool mounting section 118. From the center of the tool mounting hole 120 to the direction of the tool locking sleeve 116, the tool mounting section 118 gradually tilts toward the direction of the tool locking sleeve 116.

[0040] In one embodiment of the present invention, the design of the spline shaft 106 is further optimized. A special tool installation section 118 is provided on the spline shaft 106, and this design is intended to provide a stable and accurate tool installation platform. The tool locking sleeve 116 is sleeved on the tool installation section 118 to ensure that the tool is firmly fixed.

[0041] In particular, a tool mounting hole 120 is provided at the end of the tool mounting section 118 for mounting a tool. It is worth noting that from the center of the tool mounting hole 120 to the direction of the tool locking sleeve 116, the tool mounting section 118 gradually presents a trend of tilting toward the tool locking sleeve 116.

[0042] The inclined tool mounting section 118 provides a natural guide surface for the installation of the tool. When the tool is inserted into the tool mounting hole 120, this inclined surface can help the tool to be positioned to a predetermined position more easily and accurately.

[0043] When the tool is fully inserted and fixed, the inclined tool mounting section 118 and the tool locking sleeve 116 work together to form a more secure locking structure. This design helps prevent the tool from loosening due to vibration or external force during processing.

[0044] The inclined tool mounting section 118 can also optimize the stress distribution of the tool during the machining process. By adjusting the inclination angle, the tool can be made more stable when subjected to cutting force, reducing tool damage caused by stress concentration.

[0045] The inclined tool mounting section 118 provides a precise guide surface for the installation of the tool, which helps to ensure the stability and accuracy of the tool during the processing. Through the inclined design, the tool mounting section 118 and the tool locking sleeve 116 together form a more secure locking structure, which effectively prevents the tool from loosening and falling off. The inclined tool mounting section 118 helps to optimize the stress distribution of the tool during the processing, reduces tool damage caused by stress concentration, and thus extends the service life of the tool. Since the tool installation is more precise and stable, the downtime and maintenance costs caused by tool problems can be reduced, thereby improving processing efficiency and production efficiency.

[0046] According to one embodiment of the present invention, the deceleration assembly comprises: The driving tooth 122 is mounted on the output end of the first driving member 102; Idle gear teeth 124 are drivingly connected to the driving gear 122; The driven gear set 126 is drivingly connected to the idler gear teeth 124 .

[0047] In one embodiment of the present invention, the reduction assembly is designed as a compact and efficient transmission system.

[0048] The driving tooth 122 is installed at the output end of the first driving member 102. As the starting transmission element of the reduction assembly, the driving tooth 122 is responsible for receiving the power from the first driving member 102 and transmitting it to the subsequent transmission elements. The parameters such as the tooth shape, module and helix angle of the driving tooth 122 are carefully calculated to ensure the best transmission efficiency and load-bearing capacity.

[0049] The idler gear teeth 124 are connected to the driving gear 122. The main function of the idler gear teeth 124 is to change the transmission direction or transmit power to a further driven element, and it does not directly participate in the power output. In the reduction assembly, the idler gear teeth 124 act as a bridge to smoothly transmit the power of the driving gear 122 to the driven gear set 126. The material, size and position of the idler gear teeth 124 are precisely designed to ensure the smoothness and reliability of the transmission.

[0050] The driven gear set 126 is connected to the idler gear 124. As the final transmission element of the reduction assembly, the driven gear set 126 is responsible for receiving the power from the idler gear 124 and converting it into the required output speed and torque. The driven gear set 126 may be composed of one or more driven gear sets 126, and the specific number depends on the required reduction ratio and transmission efficiency. The parameters such as the tooth shape, module and helix angle of the driven gear set 126 match the driving gear 122 and the idler gear 124 to ensure the best transmission performance.

[0051] Through a reasonable gear transmission ratio design, the reduction assembly can convert the high-speed and low-torque output of the first driving member 102 into a low-speed and high-torque output to meet the needs of specific application scenarios. The precise matching and optimized design between the active teeth 122, the idler teeth 124 and the driven gear group 126 reduce the energy loss in the transmission process and improve the transmission efficiency. The gears of the reduction assembly are made of high-strength materials and are processed by heat treatment and other processes. They have excellent load-bearing capacity and wear resistance and can adapt to harsh working environments. The reduction assembly adopts a modular design, and the various components are compactly matched, making the entire transmission system small in size, light in weight, and easy to install and maintain. The transmission ratio and gear parameters of the reduction assembly can be adjusted and optimized according to actual needs to adapt to different application scenarios and power requirements.

[0052] According to an embodiment of the present invention, the reduction assembly further includes a clutch 128 , the driven gear set 126 includes at least two different driven teeth, and the clutch 128 is used to switch the meshing relationship between different driven teeth and the idler gear teeth 124 .

[0053] In one embodiment of the present invention, the reduction assembly is further optimized and innovated on the original basis, a clutch 128 is added, and the driven gear set 126 is improved.

[0054] The clutch 128 is introduced into the reduction assembly as a key component for switching the meshing relationship between different driven teeth and the idler gear teeth 124. The design of the clutch 128 allows the meshing relationship between different driven teeth and the idler gear teeth 124 to be switched without stopping the machine, thereby realizing a quick adjustment of the transmission ratio. This design greatly improves the flexibility and adaptability of the reduction assembly.

[0055] The driven teeth set 126 is designed to include at least two different driven teeth. These driven teeth have different numbers of teeth and modules, and thus can form different transmission ratios with the idler gear teeth 124. By switching the clutch 128, different driven teeth can be selected to mesh with the idler gear teeth 124, thereby adjusting the transmission ratio of the entire reduction assembly. This design enables the reduction assembly to adapt to different working requirements and speed requirements.

[0056] When the transmission ratio needs to be adjusted, the clutch 128 is operated to separate the driven tooth currently meshing with the idler gear tooth 124 from the idler gear tooth 124, while the other driven tooth meshes with the idler gear tooth 124. In this process, the design of the clutch 128 ensures the smoothness and reliability of the switching, and avoids the impact and vibration caused by the switching.

[0057] By switching the clutch 128, the transmission ratio of the reduction assembly can be easily adjusted to adapt to different working needs and speed requirements. This design greatly improves the flexibility and adaptability of the reduction assembly. The introduction of the clutch 128 makes the adjustment of the transmission ratio simpler and faster, and the switching operation can be completed without stopping, thereby improving work efficiency. The design of the clutch 128 ensures the smoothness and reliability of the switching process, avoids the impact and vibration caused by switching, and thus extends the service life of the reduction assembly. Through a reasonable gear transmission ratio design, the reduction assembly can efficiently transfer the power from the input end to the output end, reducing the loss in the energy transfer process. Combined with the design of the clutch 128 and multiple driven teeth, the reduction assembly achieves higher transmission efficiency and a wider range of applications while maintaining a compact structure.

[0058] According to one embodiment of the present invention, the reduction assembly also includes a housing 130, a support sleeve 132 is provided on the housing 130, the idler gear teeth 124 are rotatably mounted on the support sleeve 132, a wedge block 134 is provided on the support sleeve 132, and the wedge block 134 is suitable for switching between a first position and a second position. In the first position, the idler gear teeth 124 are meshed with the active gear 122, and in the second position, the idler gear teeth 124 are separated from the active gear 122.

[0059] In one embodiment of the present invention, the speed reduction assembly is innovative in structure, and related components such as a housing 130 and a support sleeve 132 are newly added.

[0060] The housing 130 is the main support and protection structure of the reduction assembly and is designed to accommodate and fix all transmission components. The material and shape of the housing 130 are optimized according to the working environment and transmission requirements of the reduction assembly to ensure sufficient rigidity and strength.

[0061] The support sleeve 132 is disposed on the housing 130 for supporting and mounting the idler gear 124. The design of the support sleeve 132 allows the idler gear 124 to rotate freely therein while ensuring the stability and accuracy of the idler gear 124 during the transmission process.

[0062] The idler gear 124 is rotatably mounted on the support sleeve 132, so that the idler gear 124 can smoothly transmit power between the driving gear 122 and the driven gear set 126. The material and tooth shape design of the idler gear 124 are optimized according to the transmission requirements to ensure the best transmission efficiency and load-bearing capacity.

[0063] The wedge block 134 is disposed on the support sleeve 132 and can be switched between a first position and a second position. In the first position, the wedge block 134 pushes the idler gear teeth 124 toward the driving gear 122, so that the idler gear teeth 124 are closely meshed with the driving gear 122; in the second position, the wedge block 134 separates from the idler gear teeth 124 or changes the supporting position of the idler gear teeth 124, so that the idler gear teeth 124 are separated from the driving gear 122. This design allows the meshing state of the idler gear teeth 124 and the driving gear 122 to be changed by adjusting the position of the wedge block 134 without disassembling the reduction assembly.

[0064] When the deceleration assembly needs to work, the wedge block 134 is switched to the first position, pushing the idler gear 124 to mesh closely with the driving gear 122. The driving gear 122 transmits power to the driven gear set 126 through the idler gear 124, achieving low-speed and high-torque output of the driven gear set 126. When the deceleration assembly needs to be stopped or the transmission ratio needs to be adjusted, the wedge block 134 is switched to the second position, separating the idler gear 124 from the driving gear 122, thereby interrupting power transmission.

[0065] By switching the wedge block 134, the engagement and separation of the idler gear teeth 124 and the active gear 122 can be easily achieved, thereby improving the transmission flexibility of the reduction assembly. This design enables the reduction assembly to adapt to different work needs and speed requirements, and improves its scope of application. The introduction of the wedge block 134 makes the switching of the transmission state simpler and faster, and the operation can be completed without disassembling the reduction assembly, thereby improving work efficiency. The design of the wedge block 134 ensures the stability and reliability of the switching process, avoids the impact and vibration caused by switching, and thus extends the service life of the reduction assembly. The design of the housing 130 and the support sleeve 132 makes the structure of the reduction assembly more compact and reasonable, reduces unnecessary space occupation and weight, and improves its overall performance. Through a reasonable gear transmission ratio and optimized design, the reduction assembly can efficiently transfer the power of the input end to the output end, reduce the loss in the energy transfer process, and improve the transmission efficiency.

[0066] According to one embodiment of the present invention, a guide sleeve 136 is provided on the mounting seat 100, and a transmission sleeve 138 is provided on the end of the spline shaft 106 away from the processing sleeve 108. The transmission sleeve 138 is embedded in the guide sleeve 136 and a rack portion 140 is provided on the transmission sleeve 138. The rack portion 140 is transmission-connected to the first driving member 102.

[0067] In one embodiment of the present invention, the reduction assembly or the related transmission device is innovatively designed in structure, and in particular, the connection mode between the mounting seat 100 , the spline shaft 106 and the first driving member 102 is optimized.

[0068] The mounting seat 100 is designed to stably fix other transmission elements as the basic supporting structure of the entire transmission device. A guide sleeve 136 is specially provided on the mounting seat 100 to guide and support the transmission sleeve 138 of the spline shaft 106.

[0069] The guide sleeve 136 is disposed on the mounting seat 100, and its inner diameter matches the outer diameter of the transmission sleeve 138 to ensure that the transmission sleeve 138 can slide or rotate smoothly in the guide sleeve 136. The design of the guide sleeve 136 not only improves the stability of the transmission sleeve 138, but also helps to reduce friction and wear during the transmission process.

[0070] The spline shaft 106 is a key element of the transmission device, one end of which is used to connect or support a workpiece such as a processing sleeve 108, and the other end is provided with a transmission sleeve 138. The design of the transmission sleeve 138 enables the spline shaft 106 to achieve reliable transmission connection with the first driving member 102.

[0071] The transmission sleeve 138 is embedded in the guide sleeve 136, and its outer wall is tightly matched with the inner wall of the guide sleeve 136. A rack portion 140 is specially provided on the transmission sleeve 138, and the rack portion 140 extends along the axial direction of the transmission sleeve 138 and meshes with the transmission element (such as a gear, a rack, etc.) of the first driving member 102. This design enables the first driving member 102 to drive the transmission sleeve 138 and the entire spline shaft 106 to rotate or linearly move through the rack portion 140.

[0072] The first driving member 102 is used as the power source of the transmission device, and its output end is connected to the rack portion 140 of the transmission sleeve 138. The first driving member 102 can be a device that can provide rotational or linear power, such as an electric motor, a hydraulic motor, or a pneumatic motor. By adjusting the output parameters (such as speed, torque, etc.) of the first driving member 102, the motion state and transmission efficiency of the transmission sleeve 138 and the spline shaft 106 can be controlled.

[0073] The design of the guide sleeve 136 and the transmission sleeve 138 enables the spline shaft 106 to maintain high stability and accuracy during the transmission process, thereby improving the transmission accuracy of the entire transmission device. The transmission connection between the rack portion 140 and the first drive member 102 makes the transmission process more reliable and stable, reducing the risk of transmission failure caused by loosening or wear of the transmission elements. The compact design of the components such as the mounting seat 100, the guide sleeve 136 and the transmission sleeve 138 makes the structure of the entire transmission device more reasonable and compact, reducing unnecessary space occupation and weight. Through a reasonable transmission ratio and optimized design, the transmission device can efficiently transmit the power of the first drive member 102 to the spline shaft 106 and the processing sleeve 108 and other workpieces, reducing the loss during the energy transfer process. The technical solution of the present invention can be adjusted and optimized according to different transmission requirements and working environments to adapt to different application scenarios and power requirements.

[0074] According to an embodiment of the present invention, a grating ruler 142 is further provided on the mounting seat 100 , a slot 144 is provided on the guide sleeve 136 , the grating ruler 142 corresponds to the slot 144 , and the grating ruler 142 is used to detect the feed amount of the transmission sleeve 138 .

[0075] In one embodiment of the present invention, the transmission device is further innovatively designed on the mounting seat 100 , and a grating ruler 142 is introduced to detect the feed amount of the transmission sleeve 138 .

[0076] The mounting base 100 serves as a basic supporting structure of the transmission device and is not only used to fix other transmission elements, but also has a special position for mounting the grating ruler 142 .

[0077] The grating ruler 142 is a high-precision measuring device that performs precise measurement based on optical principles and provides important technical support for industrial automation. In this embodiment, the grating ruler 142 is used to detect the feed amount of the transmission sleeve 138, that is, the moving distance of the transmission sleeve 138 in the guide sleeve 136.

[0078] The guide sleeve 136 is arranged on the mounting seat 100 for guiding and supporting the transmission sleeve 138. In order to cooperate with the grating ruler 142, a slot 144 is specially provided on the guide sleeve 136.

[0079] The position, shape and size of the slot 144 match the grating ruler 142, ensuring that the grating ruler 142 can accurately detect the feed amount of the transmission sleeve 138. The design of the slot 144 not only facilitates the installation and positioning of the grating ruler 142, but also helps to improve the accuracy and stability of the measurement.

[0080] The grating ruler 142 works on the principle of moiré fringes. When the transmission sleeve 138 moves in the guide sleeve 136, the grating ruler 142 can capture the optical signal changes generated by the movement of the transmission sleeve 138. These optical signal changes are converted into digital pulse signals and processed and analyzed by a corresponding control system or data processor to obtain the precise feed amount of the transmission sleeve 138.

[0081] Feed rate is one of the important parameters in the motion control of the transmission device, which directly affects the transmission accuracy, transmission efficiency and processing quality. Through the accurate detection of the feed rate of the transmission sleeve 138 by the grating ruler 142, the real-time monitoring and control of the motion state of the transmission device can be realized, thereby improving the transmission accuracy and processing quality.

[0082] The high-precision measurement capability of the grating ruler 142 enables the feed amount of the transmission sleeve 138 to be accurately detected and controlled, thereby improving the transmission accuracy of the entire transmission device. By real-time monitoring of the feed amount of the transmission sleeve 138, deviations and errors in the transmission process can be promptly discovered and corrected, thereby enhancing the stability and reliability of the transmission. Accurate feed amount detection helps to achieve accurate control of the processing process, thereby improving processing quality and efficiency. The technical solution of the present invention can be adjusted and optimized according to different transmission requirements and working environments to adapt to different application scenarios and power requirements.

[0083] According to one embodiment of the present invention, a dovetail groove 146 is provided on the mounting seat 100 for mounting the processing device at a target position.

[0084] In one embodiment of the present invention, the transmission device or processing equipment is innovatively designed on the mounting seat 100, and a dovetail groove 146 is specially provided for mounting the processing device at a target position.

[0085] The mounting base 100 is designed to withstand enough loads and maintain stability as the supporting structure of the entire transmission device or processing equipment. On the mounting base 100, a dovetail groove 146 is specially provided to install and fix the processing device.

[0086] The target position refers to the predetermined installation position of the processing device on the transmission device or processing equipment. During the design process, the target position of the processing device is determined according to the overall layout and working requirements of the transmission device or processing equipment, and the dovetail groove 146 is opened on the mounting seat 100 accordingly.

[0087] Through the design of the dovetail groove 146, the processing device can be accurately installed and positioned on the transmission device or processing equipment, thereby improving the installation accuracy of the entire system. The shape and material of the dovetail groove 146 enable the processing device to be firmly installed on the mounting seat 100, and it is not easy to fall off or shake, thereby enhancing the stability of the entire system. Through the design of the dovetail groove 146, the installation process of the processing device can be simplified, and the installation time and cost can be reduced. The design of the dovetail groove 146 allows the processing device to be easily replaced or adjusted to adapt to different processing requirements and working conditions.

[0088] In the embodiment of the present invention, the taper of the dovetail groove can be 7°, which is convenient for installation on the track of other equipment. The taper installation can achieve high-precision centering installation, and the parallelism error with the spline shaft 106 can reach 0.003 mm.
