Description

TECHNICAL FIELD

[0001] The utility model belongs to the precise machinery manufacturing technical field, concretely relates to a pre -line body processing limiting device. BACKGROUND

[0002] In the field of pre-line body processing and manufacturing, with the continuous improvement of processing precision requirements and the increasing complexity of processing technology, positioning and limiting requirements during processing become extremely critical. The pre-line body itself has specific shape, size and structural characteristics. When performing processing operations such as cutting, drilling and polishing, it is necessary to ensure that the processing tool operates at an accurate position to avoid unnecessary damage to the pre-line body or cause processing errors. The pre-line body processing limiting device can accurately limit the movement range of the processing tool or the pre-line body itself during pre-line body processing, thereby providing necessary basic protection for accurate processing.

By the above structure, the flexible circuit board is placed in the placing groove, the cylindrical block is pressed downward, the displacement rod tends to be horizontal, the moving rod moves, the limiting rod extends outward, thereby limiting the flexible circuit board, and the motor is driven, the limiting strip is pressed against the cylindrical block, the limiting block is pressed against the flexible circuit board, thereby further limiting the flexible circuit board, and ensuring that the flexible circuit board does not displace due to external factors during operation of the machine.

[0004] Although the above technical solution can ensure that the flexible circuit board does not displace due to external factors during operation of the machine, it cannot well adapt to pre-line bodies with complex shapes or large size specifications.

Moreover, when the size of the pre-line body changes in a large range, the limiting device may need to be adjusted or replaced to meet the limiting requirements, which increases the processing cost and time cost.

DETAILED DESCRIPTION

[0023] In order to make the above objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0024] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0026] Embodiment 1

[0027] Reference Figures 1-4 For the first embodiment of the present application, the embodiment provides a pre-body machining limiting device, comprising,

[0028] The bearing mechanism 100 comprises a bearing frame 101, a support plate 102 fixedly installed on the outer side of the bearing frame 101, and a clamping assembly 103 arranged at the bottom of the support plate 102.

[0029] The limiting mechanism 200 comprises a casing 201, an air pump 202 fixedly installed on the top of the casing 201, and a limiting assembly 203 arranged at the bottom of the casing 201.

[0030] Among them, the air bag limiter 203e in the limiting assembly 203 can adapt to the shape and size change of the pre-body due to its inflatable characteristics, for the pre-body with curved surface, the air bag body 203e-1 can be inflated to fit the curved surface, realizing stable limiting, and the clamping assembly 103 can additionally assist in positioning the bottom or other parts around the pre-body.

[0031] Specifically, the limiting assembly 203 comprises a horizontal plate 203a fixedly installed on the top of the bearing frame 101, a drive motor 203b fixedly installed on the top of the horizontal plate 203a, a drive push rod 203c fixedly installed on the output end of the drive motor 203b through the output shaft, a bearing sleeve 203d movably sleeved on the end of the drive push rod 203c, and an air bag limiter 203e arranged at the end of the drive push rod 203c.

[0032] The driving motor 203b can accurately control the movement of the driving push rod 203c. During the preform processing, the driving push rod 203c can be adjusted in length according to the processing requirements, so as to drive the air bag positioner 203e to the appropriate position, thereby achieving accurate positioning of the preform.

[0033] Further, the limiting assembly 203 further comprises a hose 203f fixedly connected to the outer side of the air bag positioner 203e, a connecting pipe 203g fixedly installed at the end of the hose 203f, and a limiting block 203h fixedly installed at the outer side of the driving motor 203b. The end of the hose 203f is in communication with the air bag positioner 203e, and the top of the limiting block 203h is fixedly connected to the bottom of the shell 201.

[0034] The hose 203f communicates the air pump 202 with the air bag positioner 203e, and the connecting pipe 203g ensures the reliable connection between the hose 203f and the air bag positioner 203e. Together, they ensure that the gas can be smoothly transmitted from the air pump 202 to the air bag positioner 203e, so that the air pump 202 can be installed at an appropriate position, while providing stable air supply for the air bag positioner 203e.

[0035] Preferably, the air bag positioner 203e comprises an air bag body 203e-1 located at the outer side of the end of the driving push rod 203c, a damping shaft seat 203e-2 fixedly installed on the outer surface of the air bag body 203e-1, a rotating rod 203e-3 fittedly installed in the inner cavity of the damping shaft seat 203e-2, and a damping member 203e-4 fixedly installed at the end of the rotating rod 203e-3. The damping member 203e-4 comprises a gear 203e-4a engaged in the inner cavity of the damping shaft seat 203e-2, a plurality of grooves 203e-4b formed on the surface of the gear 203e-4a, a spring 203e-4c fixedly installed in the inner cavity of the groove 203e-4b, a tooth block 203e-4d fixedly installed at the end of the spring 203e-4c, a clamping block 203e-4e fixedly installed at the bottom of the tooth block 203e-4d, and a clamping groove 203e-4f formed on the inner surface of the groove 203e-4b, wherein the clamping block 203e-4e is movably clamped in the inner cavity of the clamping groove 203e-4f.

[0036] The air bag body 203e-1 is directly in contact with the preform and achieves the limiting function. Due to the inflatable characteristics, the air bag body 203e-1 can adapt to the shape and size changes of the preform. When the shape of the preform is irregular or the size fluctuates within a certain range, the air bag body 203e-1 can change its shape by adjusting the inflation amount, tightly fit the surface of the preform, and provide uniform limiting force. For the preform with a curved surface, the air bag body 203e-1 can inflate and expand to fit the curved surface, achieving stable limiting. The damping member 203e-4 can play a role in buffering and shock absorption during the contact between the air bag limiter 203e and the preform. When the preform collides with the air bag limiter 203e or has relative movement, the damping member 203e-4 can consume energy through the movement of the rotating rod 203e-3 in the damping shaft seat 203e-2, reducing the impact force on the device and the preform. When the preform quickly enters the limiting device, the damping member 203e-4 can avoid damage to the preform caused by sudden impact, and also protect the internal components of the device from excessive impact force.

[0037] In use, first place the preform at the limiting assembly 203, the clamping assembly 103 starts to work, the rotating disc 103a, the first mechanical arm 103b, the second mechanical arm 103c, the drive shaft 103d, the positioning block 103e and the protrusion 103f cooperate with each other to preliminarily position and clamp the preform.

[0038] The drive motor 203b starts to drive the drive push rod 203c to move, the bearing sleeve 203d reduces the friction of the drive push rod 203c movement, and the air bag limiter 203e at the end of the drive push rod 203c reaches the appropriate position. In this process, the inflation pump 202 in the limiting mechanism 200 can inflate the air bag body 203e-1 of the air bag limiter 203e through the hose 203f and the connecting pipe 203g according to the shape of the preform and the processing requirements, so that the air bag body 203e-1 is in contact with the preform, the damping member 203e-4 plays a role in buffering and shock absorption, and the limiting block 203h limits the movement range of the drive motor 203b, thereby completing the accurate limiting processing of the preform.

[0039] In summary, the limiting assembly 203 can adapt to the shape and size changes of the preform through the cooperation between various structures. For the preform with a curved surface, the air bag body 203e-1 can inflate and expand to fit the curved surface, achieving stable limiting. The clamping assembly 103 can additionally assist in positioning the bottom or other parts of the preform.

[0040] Embodiment 2

[0041] Reference Figure 1 and Figure 4The second embodiment of the utility model differs from the previous embodiment in that the embodiment provides auxiliary clamping and positioning of the preform.

[0042] Specifically, the clamping assembly 103 includes a rotating disc 103a fixedly installed at the bottom of the support plate 102, a first mechanical arm 103b fixedly installed at the bottom of the rotating disc 103a, a second mechanical arm 103c hingedly connected at the end of the first mechanical arm 103b, a driving shaft 103d fixedly installed at the end of the second mechanical arm 103c, a positioning block 103e fixedly installed outside the driving shaft 103d, and a protruding block 103f fixedly installed outside the positioning block 103e.

[0043] The clamping assembly 103 provides multi-dimensional auxiliary positioning and limiting functions for the preform through the coordinated action of multiple components, can adapt to preforms of different shapes and sizes, improves the stability of the preform during the machining process, reduces machining errors, and can flexibly adjust the clamping force and position, which helps to improve the precision and efficiency of the entire machining process.

[0044] In use, the rotating disc 103a can perform rotational motion to drive the first mechanical arm 103b to adjust the orientation, the second mechanical arm 103c can continue to change the angle relative to the first mechanical arm 103b to adjust the position in different planes, the driving shaft 103d can be rotated as needed, the positioning block 103e is used to determine the approximate position of the preform, and the protruding block 103f further increases the contact stability with the preform to position and limit the preform from multiple directions, ensuring that the preform maintains an accurate position during the machining process.

[0045] In summary, the clamping assembly 103 can adapt to preforms of different shapes and sizes, improves the stability of the preform during the machining process, reduces machining errors, and can flexibly adjust the clamping force and position, which helps to improve the precision and efficiency of the entire machining process.
