Description
Technical Field
[0001] This utility model relates to the field of vacuum pump processing technology, specifically a quick positioning and locking device for a vacuum pump base. Background Technology
[0002] When machining large batches of vacuum pump bases, traditional machining centers require hole diameter and orientation positioning for each base due to its irregular shape, which takes a long time. After flipping the base, hole diameter and orientation positioning must be performed again, with the two positioning and locking processes taking at least 10 minutes. This clamping method is inefficient, delays the production cycle, and is a huge waste of equipment and manpower. Therefore, there is an urgent need for a device that can quickly position and lock vacuum pump bases. Utility Model Content
[0003] The purpose of this invention is to provide a quick positioning and locking device for a vacuum pump base, so as to solve the problems mentioned in the background art.
[0004] This utility model provides the following technical solution: a quick positioning and locking device for a vacuum pump base, including a mounting base. Several sets of reverse locking mechanisms and front locking mechanisms for mounting and positioning the vacuum pump base are respectively arranged on the top side of the mounting base. The reverse locking mechanisms and front locking mechanisms are symmetrically arranged at equal intervals on both halves of the mounting base. A pressure monitoring device is arranged near the air inlet of the reverse locking mechanism and the front locking mechanism to monitor the effectiveness of the pressure locking device in real time. A directional positioning block is fixedly installed on the top side of the mounting base corresponding to the front locking mechanism. Two sets of pressure valve plates controlling the reverse locking mechanism and the front locking mechanism are arranged on one side of the front of the mounting base. Each set of reverse locking... A gas pipe connects the mechanism and the front locking mechanism, and the gas pipes are connected to each other through a T-junction. The center of the reverse locking mechanism and the front locking mechanism is provided with a positioning rod for centering the vacuum pump base. It also includes a locking bracket installed on the top side of the vacuum pump base for positioning and distributing pressure. Gas is supplied to the reverse locking mechanism to provide power to the reverse locking mechanism and the front locking mechanism, which can then be activated to clamp and position the reverse and front sides of the vacuum pump base. The stability of the front clamping is further improved by the directional positioning block, and the pressure of the reverse locking mechanism and the front locking mechanism is distributed by the locking bracket, so that the force is more even when the vacuum pump is clamped.
[0005] As an optimization, the reverse locking mechanism and the front locking mechanism are pneumatic locking mechanisms, and are connected to an external pneumatic power source through air pipes.
[0006] As an optimization, the reverse locking mechanism is circular in shape and has a pin hole on the outer side of its outer circle to facilitate the installation and positioning of the vacuum pump base.
[0007] As an optimization, the orientation positioning block has a groove adapted to the structure of the vacuum pump base and is also provided with a spring locking pin. The groove adapted to the vacuum pump base and the spring locking pin facilitate the installation and positioning of the front of the vacuum pump base.
[0008] As an optimization, the locking bracket has several intersecting connecting rods inside, and a positioning plate is fixedly installed at the corresponding positioning rod of each connecting rod. The center of the positioning plate has a notch corresponding to the locking bracket, and the center of the positioning plate has a groove for positioning the locking bracket. By installing the locking bracket as a whole on the top of the vacuum pump after positioning, and pushing the locking bracket so that the positioning rod enters the groove along the notch, the positioning can be locked, thereby improving the stability of the locking bracket after installation.
[0009] As an optimization, the positioning rod includes a support rod slidably inserted into the fixed sleeve, a locking head fixedly installed at the top of the support rod, and a slider fixedly installed on the outer side of the section of the support rod inside the fixed sleeve. A compression spring is fixedly installed between the slider and the bottom wall of the fixed sleeve. When the support rod is inserted into the notch, the locking head is squeezed, which lifts the locking head upward. This causes the slider to stretch the compression spring upward. After the locking head is fully inserted into the groove, the spring's own rebound force can lock the locking head into the groove, thereby improving stability.
[0010] As an optimization, limit blocks are fixedly installed on both sides of the slider, and limit grooves are opened on the inner side walls of the fixed sleeve corresponding to the limit blocks. The limit blocks are slidably connected in the limit grooves. When the slider slides, it will drive the limit blocks to slide inside the limit grooves, thereby playing a limiting and guiding role, preventing the support rod from rotating and allowing it to slide only vertically.
[0011] Compared with the prior art, the beneficial effects of this utility model include: the vacuum pump base quick positioning and locking device, by supplying gas to the reverse locking mechanism and the front locking mechanism through the reverse locking mechanism, can activate the reverse locking mechanism and the front locking mechanism to clamp and position the reverse and front of the vacuum pump base. The directional positioning block further improves the stability of the front clamping, and the locking bracket distributes the pressure of the reverse locking mechanism and the front locking mechanism, making the force more uniform when clamping the vacuum pump, thereby fully improving the utilization rate of the equipment and reducing the clamping and correction time of parts, significantly reducing the product processing cycle; the vacuum pump base quick positioning and locking device, by pushing the locking bracket, causes the support rod to enter the groove along the notch, which will squeeze the clamp head and lift the clamp head upward, thus driving the slider upward to stretch the compression spring. After the clamp head is fully inserted into the groove, the compression spring itself can drive the clamp head to lock in the groove, thereby further improving the stability of the installation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3This utility model provides a technical solution: a vacuum pump base quick positioning and locking device, including a mounting base 1. The top side of the mounting base 1 is respectively provided with twelve sets of reverse locking mechanisms 2 and front locking mechanisms 3 for mounting and positioning the vacuum pump base. The reverse locking mechanisms 2 and front locking mechanisms 3 are arranged in a 4-row, 6-column configuration. A pressure monitoring device is installed near the air inlet of the reverse locking mechanisms 2 and front locking mechanisms 3 to monitor the effectiveness of the pressure locking device in real time. A directional positioning block 4 is fixedly installed on the top side of the mounting base 1 corresponding to the front locking mechanism 3. Two sets of pressure valve plates 5 are provided on the front side of the mounting base 1 to control the reverse locking mechanisms 2 and front locking mechanisms 3 respectively. Each set of reverse locking mechanisms 2 and front locking mechanisms 3 is connected by an air pipe 6. The reverse locking mechanisms 2 and front locking mechanisms 3 are pressure locking mechanisms, and are... The air pipe 6 is connected to an external pneumatic power source, and the sections of the air pipe 6 are connected by a three-way pipe 7. The center of the reverse locking mechanism 2 and the front locking mechanism 3 is provided with a positioning rod 8 for centering the vacuum pump base. It also includes a locking bracket 9 installed on the top side of the vacuum pump base for positioning and distributing pressure. Gas is supplied to the reverse locking mechanism 2 and the front locking mechanism 3 to provide power, which can start the reverse locking mechanism 2 and the front locking mechanism 3 to clamp and position the reverse and front sides of the vacuum pump base. The directional positioning block 4 further improves the stability of the front clamping, and the locking bracket 9 distributes the pressure of the reverse locking mechanism 2 and the front locking mechanism 3, so that the force is more even when the vacuum pump is clamped. This can fully improve the utilization rate of the equipment and reduce the clamping and correction time of parts, and significantly reduce the processing cycle of the product.
[0016] Please see Figure 1-3 The reverse locking mechanism 2 is in the shape of an outer circle, and a pin hole is provided on the outer side of its outer circle to facilitate the installation and positioning of the vacuum pump base. The directional positioning block 4 has a groove that adapts to the structure of the vacuum pump base, and also has a spring locking pin. Through the groove that adapts to the vacuum pump base and the spring locking pin, it is convenient to install and position the front of the vacuum pump base. Please see Figure 4 The locking bracket 9 has several intersecting connecting rods inside, and a positioning plate 10 is fixedly installed at the corresponding positioning rod 8. The center of the positioning plate 10 has a notch 11 corresponding to the locking bracket 9, and the center of the positioning plate 10 has a groove 12 for positioning the locking bracket 9. By installing the locking bracket 9 as a whole on the top of the vacuum pump after positioning, and pushing the locking bracket 9 so that the positioning rod 8 enters the groove 12 along the notch 11, the positioning can be locked, thereby improving the stability of the locking bracket 9 after installation. Please see Figure 5The positioning rod 8 includes a support rod 14 slidably inserted inside the fixed sleeve 13, a locking head 15 fixedly installed at the top of the support rod 14, a slider 16 fixedly installed on the outer side of a section of the support rod 14 inside the fixed sleeve 13, and a compression spring 17 fixedly installed between the slider 16 and the bottom wall of the fixed sleeve 13. When the support rod 14 is inserted into the notch 11, the locking head 15 will be squeezed, which will lift the locking head 15 upward. This will cause the slider 16 to stretch the compression spring 17 upward. After the locking head 15 is fully inserted into the groove 12, the compression spring 17 can be used to lock the locking head 15 into the groove 12, thereby improving stability. Please see Figure 5 Limiting blocks 18 are fixedly installed on both sides of the slider 16. Limiting grooves 19 are opened on the inner side walls of the fixed sleeve 13 corresponding to the limiting blocks 18, and the limiting blocks 18 are slidably connected in the limiting grooves 19. The sliding of the slider 16 will drive the limiting blocks 18 to slide inside the limiting grooves 19, thereby playing a limiting and guiding role, preventing the support rod 14 from rotating and allowing it to slide only vertically.
[0017] The pneumatic locking mechanism, pneumatic monitoring device, spring pin, etc. are references to existing technologies, and will not be described in detail in this application. When using them, the preferred method can be selected under the premise of meeting the driving conditions.
[0018] Working principle: When clamping the vacuum pump base, simply place the vacuum pump base stably on top of the front locking mechanism 3. The hole and end face on the vacuum pump base are self-centered with the outer circle and end face on the front locking mechanism 3. One side of the outer circle of the air inlet of the vacuum pump base rests on the end face of the positioning groove on the directional positioning block 4, and the other side is locked by the spring device. At this time, the front locking mechanism 3 has completed the clamping of one base. When clamping from the reverse side, the holes and end faces on the vacuum pump base are self-centered with the outer circle and end face on the reverse locking mechanism 2. The circumferential positioning of the vacuum pump base is completed by the positioning pin on the reverse locking mechanism 2 cooperating with the inner hole on the base. At the same time, the pressure of the reverse locking mechanism 2 and the front locking mechanism 3 is distributed by installing the locking bracket 9, so that the force is more even when the vacuum pump is clamped.
[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
