[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0035] Example 1
[0036] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a clamping fixture with movable core pulling. The clamping fixture with movable core pulling includes a bearing component 1, a product body 2 and an air supply component 3. By setting the bearing component 1 and the air supply component 3, a preliminary side positioning can be performed, followed by a stable clamping operation. The overall operation sequence is controlled quickly and conveniently, reducing positioning time and facilitating the efficient execution of subsequent machining processes.
[0037] Specifically, the bearing assembly 1 includes a bearing plate 11, a side positioning seat 12 fixed on the top of the bearing plate 11, a side push cylinder 13 fixed on the top of the bearing plate 11, a pressing component 14 provided on the bearing plate 11, a lifting cylinder 15 fixed on the bearing plate 11, and a positioning column 16 fixed at the output end of the lifting cylinder 15.
[0038] With the side positioning seat 12 and the side push cylinder 13, the side positioning seat 12 can support the downward-moving product body 2, and then, in conjunction with the side push cylinder 13 which extends, the product body 2 can be initially positioned and installed.
[0039] Specifically, the product body 2 is located on the top of the support plate 11, including the product base 21 located on the top of the side positioning seat 12.
[0040] Specifically, the gas delivery assembly 3 is located at the bottom of the support plate 11 and includes a sequence regulating valve 31 fixed to the bottom of the support plate 11. A transmission head 32 is provided on the outside of the sequence regulating valve 31, and a filter element 33 is installed inside the transmission head 32.
[0041] The sequential control valve 31 is a pressure control valve that controls multiple actuators to operate in a predetermined sequence through a fluid pressure signal. It is widely used in hydraulic and pneumatic industrial systems. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here. In this application, the sequential control valve 31 can be used to make the side push cylinder 13 act first, which drives multiple pressing parts 14 to act and clamp, and finally the lifting cylinder 15 acts to drive the positioning column 16 to move down.
[0042] Example 2
[0043] Reference Figures 2 to 10 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0044] Specifically, the pressing component 14 includes a fixed seat 14-1 fixed to the top of the bearing plate 11, a pressing cylinder 14-2 bolted to the bottom of the fixed seat 14-1, a movable rod 14-3 rotatably connected to the output end of the pressing cylinder 14-2, and a movable block 14-4 rotatably connected to the bottom end of the movable rod 14-3.
[0045] A support column 14-5 is fixed to the top of the fixed base 14-1, a pressure block 14-31 is fixed on the movable rod 14-3, and the bottom end of the movable block 14-4 is rotatably connected to the fixed base 14-1.
[0046] The movable rod 14-3 is L-shaped. When the pressing cylinder 14-2 extends, the short part of the movable rod 14-3 tilts up, so that the long part of the movable rod 14-3 rotates and closes under the connection of the movable block 14-4, and then the pressing block 14-31 presses the product base 21.
[0047] The support columns 14-5 can support and position the bottom of the product base 21, ensuring the flatness and stability of the product base 21.
[0048] The product base 21 has a pressure groove 22 on its top side, which is slidably connected to the pressure block 14-31. The product base 21 has a positioning hole 23, which is slidably engaged with the positioning post 16.
[0049] By setting up the pressure groove 22 and the pressure block 14-31, multiple pressure blocks 14-31 and pressure groove 22 can cooperate to press and position the product base 21 in multiple positions when the movable rod 14-3 moves.
[0050] The positioning holes 23 and positioning posts 16 are designed to assist in positioning, which helps operators to quickly and accurately lower and place the product base 21.
[0051] The sequential regulating valve 31 is equipped with an air inlet 31-1, and there are two transmission heads 32, one of which is fixed inside the air inlet 31-1, and the other is fixed to the bottom of the support plate 11.
[0052] One end of the transmission head 32 has a slot 32-1, and the inside of the transmission head 32 has a screw groove 32-2.
[0053] The filter element 33 includes a housing 33-1 disposed between two transmission heads 32, and an integrated mesh plate 33-2 is fixed inside the housing 33-1.
[0054] Both ends of the housing 33-1 are slidably connected to connecting sleeves 33-3 and sealed. The connection between the thread 33-31 and the thread groove 32-2 is also sealed. This design is used to meet the requirements of good transmission of compressed gas in the pneumatic system.
[0055] The connecting sleeve 33-3 has a threaded opening 33-31 on the outside. The two threads 33-31 rotate in opposite directions and are threadedly connected to the threaded groove 32-2.
[0056] A spring 33-4 is fixed between the two connecting sleeves 33-3.
[0057] The central angle of the slot 32-1 is 180 degrees, which is used to meet the lateral movement space requirements of the connecting sleeve 33-3.
[0058] The integrated mesh plate 33-2 consists of a dust filter and an activated carbon mesh plate that adsorbs moisture, arranged sequentially from the external air source to the air inlet 31-1. Both the filter and the activated carbon mesh plate are cone-shaped. This design increases the contact area with the transmitted gas, achieving good filtration, impurity removal, and moisture absorption protection.
[0059] The outer shell of the storage shell 33-1 and the inner wall of the connecting sleeve 33-3 are both hexagonal. With this design, when one connecting sleeve 33-3 is driven to rotate, the other connecting sleeve 33-3 will rotate synchronously in the same direction.
[0060] Since the threads 33-31 on the two connecting sleeves 33-3 rotate in opposite directions, when the connecting sleeve 33-3 is driven to rotate forward under the engagement of the threaded groove 32-2, the threads 33-31 and the threaded groove 32-2 drive each other, allowing the two connecting sleeves 33-3 to move outward simultaneously and enter the transmission head 32. Similarly, when the connecting sleeve 33-3 is driven to rotate in reverse, the two connecting sleeves 33-3 will move inward simultaneously and disengage from the transmission head 32.
[0061] The spring 33-4 provides elastic support to the connecting sleeve 33-3, so that the operator does not need to press the connecting sleeve 33-3. Simply rotating the connecting sleeve 33-3 will make the thread 33-31 engage with the thread groove 32-2.
[0062] In practical applications, the external machining equipment processes the inner wall of the positioning hole 23.
[0063] When in use, first, with the positioning post 16 and the side positioning seat 12 in place, accurately place the product base 21 so that the positioning post 16 enters the positioning hole 23, the support post 14-5 supports the bottom of the product base 21, and the side of the product base 21 contacts the side positioning seat 12.
[0064] Compressed air is then fed into the sequence regulating valve 31 through the transmission head 32 and the filter element 33, which causes the side push cylinder 13 to act first, pressing the product base 21 against the side positioning seat 12. Then, multiple pressing cylinders 14-2 extend and rotate, causing the movable rod 14-3 to rotate. The pressing block 14-31, in conjunction with the pressing groove 22, stably presses and installs the product base 21. Then, the lifting cylinder 15 retracts, causing the positioning post 16 to move down and disengage from the positioning hole 23, exposing the positioning hole 23 for subsequent machining.
[0065] During the above process, when compressed air flows through the housing 33-1, it is intercepted and purified by the integrated mesh plate 33-2, ensuring gas cleanliness. As the usage time increases, when it is necessary to disassemble and replace the filter element 33, simply reverse the connecting sleeve 33-3 so that the thread 33-31 is no longer threaded into the threaded groove 32-2, and then move the connecting sleeve 33-3 through the slot 32-1 to remove it. Similarly, when installing the filter element 33, simply move the connecting sleeve 33-3 through the slot 32-1 to align the thread 33-31, and then rotate the connecting sleeve 33-3 forward. Under the support of the spring 33-4, a screwing force is applied to the connecting sleeve 33-3, which is beneficial to the installation process. At the same time, in the installed state, the friction force of the connecting sleeve 33-3 is increased to prevent the connecting sleeve 33-3 from rotating and moving out at will, thus improving safety.
[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
