Description
Technical Field
[0001] The utility model relates to the technical field of trays, in particular to a tray for fixing multiple valve bodies. Background Art
[0002] In the modern injection molding industry, hydraulic valve plates are key components that face an increasing demand for precise and efficient processing. Valve plates are made from valve body raw materials through multiple processes such as milling, drilling, and tapping. Traditional valve plate processing requires the valve body to be clamped and fixed separately on different processing equipment, which is very inefficient.
[0003] With the popularity of flexible production lines, automation and process optimization of valve plate production for injection molding machines have become crucial. Existing automation solutions usually place valve bodies on storable shelf pallets, which are automatically grasped and transported by robots. However, the existing pallet design has the following limitations: Due to the diverse specifications and sizes of valve plates, existing pallets can usually only clamp and fix valve body materials of a single specification, which cannot meet the needs of simultaneous processing of valve bodies of multiple specifications.
[0004] To solve the above problems, there is an urgent need for a pallet that can simultaneously fix multiple valve bodies of different specifications and effectively prevent the valve bodies from moving, so as to improve the processing efficiency and precision of the valve plate and meet the needs of flexible production lines. Utility Model Content
[0005] The purpose of the utility model is to solve the defects in the prior art and provide a multi-valve body fixing tray that can simultaneously fix multiple valve bodies of different specifications and effectively prevent the valve bodies from moving.
[0006] The cam is secured to the base by a spring, and the cam is secured to the base by a spring, and the cam is secured to the base by a spring, and the cam is secured to the base by a spring.
[0007] Compared with the existing technology, the benefits of the present invention are: the present invention realizes flexible adjustment of the size of the clamping area by arranging the first fixed block and the second fixed block on the track and utilizing the cooperation of the wedge block and the sliding block. When it is necessary to clamp valve bodies of different specifications, it is only necessary to adjust the fixed positions of the first fixed block and the second fixed block on the track to change the size of the clamping area, thereby ensuring the clamping and fixation of valve bodies of different specifications, thereby improving the applicability and flexibility of the pallet.
[0008] As an improvement, two adjacent rails form a support rail assembly for positioning the clamping mechanism. An expansion rail is installed on one side of the support rail assembly, and the clamping mechanism is installed on the expansion rail. The expansion rail effectively enhances the pallet's applicability, allowing it to clamp valve bodies with larger longitudinal dimensions. When a larger valve body needs to be clamped, the clamping mechanism can be installed on the expansion rail, thereby expanding the longitudinal range of the clamping area.
[0009] Specifically, the track is provided with an inverted T-shaped groove extending along its length direction, and a first T-shaped block corresponding to the first fixed block and a second T-shaped block corresponding to the second fixed block are slidably arranged in the inverted T-shaped groove, the first T-shaped block is provided with a first threaded hole, a first bolt is threadedly connected in the first threaded hole, the first fixing block is provided with a first through hole for inserting the first bolt, the first fixing block is locked and fixed to the track by the first bolt, the second T-shaped block is provided with a second threaded hole, a second bolt is threadedly connected in the second threaded hole, the second fixing block is provided with a second through hole for inserting the second bolt, and the second fixing block is locked and fixed to the track by the second bolt. This structural design can firmly lock and fix the first fixing block and the second fixing block to the track, and has the advantages of simple structure and easy implementation. When in use, the first fixing block and the second fixing block are firmly fixed through the threaded connection of the bolts and the T-block, effectively preventing loosening when clamping the valve body, ensuring the stability and reliability of the clamping. At the same time, the design of the inverted T-slot, combined with the bolts and T-blocks, allows the first fixing block and the second fixing block to slide freely on the track, making it convenient to quickly adjust the size of the clamping area according to valve bodies of different specifications, thereby improving the practicality and ease of operation of the pallet.
[0010] Specifically, the locking mechanism includes a third bolt and a third T-shaped block corresponding to the wedge block. The third T-shaped block is slidably arranged in the inverted T-shaped groove and has a third threaded hole for threading the third bolt. The wedge block is provided with a third through hole for inserting the third bolt. The wedge block is locked and fixed to the track by the third bolt. The locking mechanism of this structural design has the advantages of simple structure, low cost, and easy implementation. When in use, the third bolt is used to drive the third T-shaped block to rise and press it into the inverted T-shaped groove. At the same time, the bolt head of the third bolt descends and presses the wedge block. The inclined structure of the wedge block transmits pressure to push the sliding block to slide toward the clamping area, thereby clamping and fixing the valve body. When the sliding block and the first fixed block clamp the valve body in the clamping area, the locking mechanism locks and fixes the wedge block between the sliding block, the second fixed block and the track, ensuring stability and reliability during the clamping process.
[0011] As an improvement, a first placement step is provided at the rear bottom of the first fixed block, extending into the clamping area, and a second placement step is provided at the front bottom of the sliding block, extending into the clamping area. This structure prevents the valve body from directly contacting the track, effectively protecting the track's integrity. The placement step also serves as an auxiliary clamping mechanism, making the valve body more secure during the clamping process and avoiding machining errors caused by loosening.
[0012] As an improvement, a limit plate is provided on the outer wall of the first fixed block. One end of the limit plate is detachably connected to the first fixed block, and the other end of the limit plate extends into the clamping area. In this structure, the provision of the limit plate simplifies the valve body positioning operation. The operator only needs to place the valve body into the clamping area to achieve accurate positioning, avoiding the tedious steps of manually adjusting the valve body position and improving production efficiency. At the same time, the provision of the limit plate can effectively prevent the valve body from shifting during the clamping process, ensuring that the valve body is always in the preset position, thereby improving the accuracy and consistency of valve body processing.
[0013] As an improvement, the front and rear ends of the wedge block have a first dovetail guide block and a second dovetail guide block, the rear end of the sliding block is provided with a first dovetail guide groove that plugs into and mates with the first dovetail guide block, the front end of the second fixed block is provided with a second dovetail guide groove that plugs into and mates with the second dovetail guide block, and the bottom of the sliding block is fixedly provided with a sliding limit block that slides in an inverted T-shaped groove. This structural design effectively prevents the sliding block and the wedge block from sliding off to the sides of the track when the wedge block is pressed down. The two dovetail guide blocks on the wedge block plug in and mate with the two dovetail guide grooves, allowing the wedge block to move up and down along the plug-in mating surface between the sliding block and the second fixed block, preventing it from moving off to the sides of the track. At the same time, the sliding block is prevented from slipping off to the sides of the track when it slides back and forth on the track through the sliding limit block. This structural design not only improves the stability and reliability of the clamping mechanism, but also simplifies the structural design and enhances the overall performance of the clamping mechanism.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0022] like Figure 1 、 Figure 3 and Figure 4 As shown, in the utility model, the multi-valve body fixing tray includes a base 1 and a plurality of clamping mechanisms 2 arranged on the base 1. At least two rails 3 are arranged in parallel and spaced apart on the top of the base 1. The clamping mechanism 2 includes a first fixed block 21, a sliding block 24, a wedge block 23 and a second fixed block 22 arranged on the rail 3 from front to back. The first fixed block 21 and the second fixed block 22 are positioned and arranged on the rail 3 along the front-to-back direction. The sliding block 24 is slidably arranged on the rail 3. A clamping area 20 is formed between the sliding block 24 and the first fixed block 21. The wedge block 23 abuts between the sliding block 24 and the second fixed block 22, and the contact surfaces of the wedge block 23 and the sliding block 24 slide obliquely up and down, and are inclined from top to bottom toward the direction of the second fixed block 22. A locking mechanism 4 is provided between the wedge block 23 and the track 3, and the locking mechanism 4 is used to drive the wedge block 23 to move downward and push the sliding block 24 to slide toward the clamping area 20. When the sliding block 24 and the first fixed block 21 clamp the valve body in the clamping area 20, the locking mechanism 4 locks the wedge block 23 between the sliding block 24, the second fixed block 22 and the track 3.
[0023] The present utility model achieves flexible adjustment of the size of the clamping area 20 by providing a first fixing block 21 and a second fixing block 22 on the track 3 and utilizing the cooperation of the wedge block 23 and the sliding block 24. When it is necessary to clamp valve bodies of different specifications, the size of the clamping area 20 can be changed by simply adjusting the fixed positions of the first fixing block 21 and the second fixing block 22 on the track 3, thereby ensuring the clamping and fixation of valve bodies of different specifications and improving the applicability and flexibility of the pallet. Its operating principle is to utilize the cooperation of the inclined surface of the wedge block 23 and the sliding block 24, and drive the wedge block 23 downward through the locking mechanism 4, pushing the sliding block 24 to slide toward the clamping area 20, thereby achieving clamping and fixation of the valve body.
[0024] like Figure 1 and Figure 2As shown, two adjacent rails 3 form a support rail assembly for positioning the clamping mechanism 2. An expansion rail 31 is provided on one side of the support rail assembly, and the clamping mechanism 2 is mounted on the expansion rail 31. The provision of the expansion rail 31 effectively enhances the pallet's applicability, enabling it to clamp valve bodies with larger longitudinal dimensions. When a larger valve body needs to be clamped, the clamping mechanism 2 can be mounted on the expansion rail 31, thereby expanding the longitudinal extent of the clamping area 20. The operating principle is to utilize the additional space provided by the expansion rail 31 to install the clamping mechanism 2 on the expansion rail 31, thereby increasing the longitudinal dimension of the clamping area 20 and enabling the clamping and securing of larger valve bodies.
[0025] like Figure 2 and Figure 3 As shown, the rail 3 is provided with an inverted T-shaped slot 30 extending along its length direction, and a first T-shaped block 51 corresponding to the first fixed block 21 and a second T-shaped block 52 corresponding to the second fixed block 22 are slidably arranged in the inverted T-shaped slot 30. The first T-shaped block 51 is provided with a first threaded hole 61, and a first bolt 71 is threadedly connected to the first threaded hole 61. The first fixing block 21 is provided with a first through hole 81 for inserting the first bolt 71. The first fixing block 21 is locked and fixed to the rail 3 by the first bolt 71. The second T-shaped block 52 is provided with a second threaded hole 62, and a second bolt 72 is threadedly connected to the second threaded hole 62. The second fixing block 22 is provided with a second through hole 82 for inserting the second bolt 72. The second fixing block 22 is locked and fixed to the rail 3 by the second bolt 72. This structural design can more firmly lock and fix the first fixing block 21 and the second fixing block 22 to the track 3, and has the advantages of simple structure and easy implementation. When in use, the first fixing block 21 and the second fixing block 22 are firmly fixed by the threaded connection of the bolts and the T-block, which effectively prevents loosening when clamping the valve body and ensures the stability and reliability of the clamping. At the same time, the design of the inverted T-slot 30, combined with the bolts and T-blocks, allows the first fixing block 21 and the second fixing block 22 to slide freely on the track 3, making it convenient to quickly adjust the size of the clamping area 20 according to valve bodies of different specifications, thereby improving the practicality and ease of operation of the pallet.
[0026] like Figure 3As shown, the locking mechanism 4 includes a third bolt 73 and a third T-block 53 arranged corresponding to the wedge block 23. The third T-block 53 is slidably arranged in the inverted T-slot 30 and has a third threaded hole 63 for threaded connection of the third bolt 73. A third through hole 83 is provided on the wedge block 23 for inserting the third bolt 73. The wedge block 23 is locked and fixed on the rail 3 by the third bolt 73. The locking mechanism 4 of this structural design has the advantages of simple structure, low cost and easy implementation. When in use, the third bolt 73 is used to drive the third T-block 53 to rise and press it into the inverted T-slot 30. At the same time, the bolt head of the third bolt 73 descends and presses the wedge block 23. Through the inclined structure of the wedge block 23, the pressure is transmitted to push the sliding block 24 to slide toward the clamping area 20, thereby clamping and fixing the valve body. When the sliding block 24 and the first fixed block 21 clamp the valve body in the clamping area 20, the locking mechanism 4 locks and fixes the wedge block 23 between the sliding block 24, the second fixed block 22 and the track 3, ensuring stability and reliability during the clamping process.
[0027] like Figure 3 or Figure 5 As shown, the rear end bottom of the first fixed block 21 is provided with a first placement step 91 that extends into the clamping area 20, and the front end bottom of the sliding block 24 is provided with a second placement step 92 that extends into the clamping area 20. With this structure, the placement steps prevent the valve body from directly contacting the track 3, effectively protecting the integrity of the track 3. At the same time, the placement steps also serve to assist in clamping, making the valve body more secure during the clamping process and avoiding processing errors caused by loosening.
[0028] like Figure 5As shown, a limiting plate 9 is provided on the outer wall of the first fixed block 21, and one end of the limiting plate 9 is detachably connected to the first fixed block 21, and the other end of the limiting plate 9 extends into the clamping area 20. There are many ways to implement the detachable connection between one end of the limiting plate 9 and the first fixed block 21, which can be a threaded connection, a card connection, or other fixing methods. Specifically, as a threaded connection, a through hole can be opened on the limiting plate 9, and a threaded hole can be opened on the first fixed block 21, and the limiting plate 9 can be fixed to the first fixed block 21 by bolts. As a card connection, a card slot can be opened in the first fixed block 21, and a buckle can be provided on the limiting plate 9 to achieve it. The advantage of the detachable connection between the limiting plate 9 and the first fixed block 21 is that when the expansion rail 31 is used, the limiting plate 9 on the track 3 between the support rail group and the expansion rail 31 can be removed to avoid structural interference. In this structure, the setting of the limit plate 9 simplifies the operating steps of valve body positioning. The operator only needs to place the valve body into the clamping area 20 to achieve accurate positioning, avoiding the tedious steps of manually adjusting the valve body position and improving production efficiency. At the same time, the setting of the limit plate 9 can effectively prevent the valve body from shifting during the clamping process, ensuring that the valve body is always in the preset position, thereby improving the accuracy and consistency of valve body processing.
[0029] like Figure 3 and Figure 5 As shown, the front and rear ends of the wedge block 23 have a first dovetail guide block 231 and a second dovetail guide block 232, the rear end of the sliding block 24 is provided with a first dovetail guide groove 240 that is plugged into and matched with the first dovetail guide block 231, the front end of the second fixed block 22 is provided with a second dovetail guide groove 220 that is plugged into and matched with the second dovetail guide block 232, and the bottom of the sliding block 24 is fixedly provided with a sliding limit block 241 that is slidably arranged in the inverted T-slot 30. This structural design effectively prevents the sliding block 24 and the wedge block 23 from sliding and detaching to the sides of the track 3 when the wedge block 23 is pressed down. The two dovetail guide blocks on the wedge block 23 are plugged into the two dovetail guide grooves to realize the lifting and lowering movement of the wedge block 23 along the plug-in fitting surface between the sliding block 24 and the second fixed block 22, avoiding movement and detachment to the sides of the track 3. At the same time, the sliding block 24 is prevented from slipping to the sides of the track 3 when sliding back and forth on the track 3 through the sliding limit block 241. This structural design not only improves the stability and reliability of the clamping mechanism 2, but also simplifies the structural design and enhances the overall performance of the clamping mechanism 2.
[0030] Although the disclosure is as described above, the scope of protection of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the scope of protection of the utility model.
