Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and more specifically, to a pull-out anodizing clamping fixture. Background Technology
[0002] The core of anodizing is placing a metal as the anode in an electrolyte solution and applying an external current to cause an oxidation reaction on its surface. The anodized film effectively isolates the metal substrate from the external environment, significantly improving its corrosion resistance. For example, it can withstand thousands of hours of corrosion in salt spray tests. The film density generated by electrolytes such as sulfuric acid and chromic acid varies, but all can enhance the protective effect after sealing treatment. During the anodizing reaction, the metal needs to be clamped and fixed using a pull-out clamping fixture to facilitate subsequent entry into the electrolyte solution. Pull-out clamps refer to those fixtures that can fix and release the workpiece through a push-pull operation.
[0003] Some existing pull-out clamping fixtures lack pressure detection structures. When the equipment clamps metal, the mechanical drive may cause excessive or insufficient clamping force, resulting in product damage. Therefore, we propose a pull-out anodizing clamping fixture. Utility Model Content
[0004] To solve the above problems, this utility model provides a pull-out anodizing clamping fixture, which adopts the following technical solution:
[0005] A pull-out anodizing clamp includes a mounting frame, in which two symmetrically distributed support blocks are slidably mounted. A dual-axis cylinder is provided on the inner wall of the top of the mounting frame. The piston shaft end of the dual-axis cylinder is fixedly connected to the opposite side of the support block on the same side. Mounting blocks are provided at the bottom of both support blocks. Clamping plates are provided on the opposite sides of the two mounting blocks. A pressure detection component is provided between the mounting blocks and the clamping plates on the same side. A lifting component is provided at the top of the mounting frame.
[0006] By adopting the above technical solution, when the equipment is in use, two support blocks are driven by a dual-axis cylinder to slide within the mounting frame. The support blocks, along with the mounting block and clamping plate on the same side, move synchronously, so that the clamping plate contacts the opposite side of the product, thus clamping and fixing the product. A pressure detection component is provided between the clamping plate and the mounting block on the same side. By setting a constant pressure value, when the clamping plate contacts the product, the clamping plate acts on the pressure detection component on the same side under the push of the dual-axis cylinder. The pressure detection component tests the pressure value on the product. When the preset constant value is reached, the operation of the dual-axis cylinder stops, achieving the effect of protecting the product. This helps to prevent the product from being damaged due to excessive clamping force and also helps to prevent the product from falling due to insufficient clamping force. A lifting component is provided at the top of the mounting frame to adjust the height of the product, facilitating the subsequent processing of the product in the electrolyte.
[0007] Furthermore, the pressure detection assembly includes a support column fixedly installed on one side of two mounting blocks. Each of the two support columns has a movable groove on one side. A support rod is slidably installed in each of the two movable grooves. One end of each support rod is fixedly connected to the opposite side of the clamping plate on the same side. A spring is fixedly connected between the opposite ends of each support rod and the inner wall of the opposite side of the movable groove on the same side. A pressure sensor is provided on the inner wall of the opposite side of the two movable grooves. A fixing component is provided on the side wall of each support rod.
[0008] By adopting the above technical solution, when the clamping plate contacts the opposite side of the product, the clamping plate pushes the support rod to slide in the same-side movable groove under the pushing force of the dual-axis cylinder, thereby causing the same-side spring to contract, which can play a buffering role. The support rod contacts the same-side pressure sensor, which can detect the magnitude of the clamping force, helping to avoid damage to the product due to excessive clamping force, thus improving the clamping effect of the equipment. In addition, the side wall of the support rod is equipped with a fixing component. When the product is clamped stably, the support rod can be fixed by the fixing component, which helps to prevent the support rod and clamping plate from moving under the elastic force of the same-side spring due to vibration or other reasons, thus helping to maintain the clamping effect of the equipment on the product.
[0009] Furthermore, the fixing assembly includes mounting cylinders fixedly installed on the side walls of the two support columns. The bottom ends of the two mounting cylinders extend into the movable grooves on the same side. The inner walls of the top ends of the two mounting cylinders are fixedly installed with second telescopic rods. The ends of the two second telescopic rods are fixedly installed with mounting plates. The bottom ends of the two mounting plates are fixedly installed with rubber pads. The side walls of the two support columns are provided with grooves. The inner walls of the bottom ends of the two grooves are fixedly installed with multiple toothed blocks arranged in a linear array. The toothed blocks in the same group are located below the mounting plates on the same side.
[0010] By adopting the above technical solution, after the product is clamped stably, the mounting plate and rubber pad on the same side are driven to descend synchronously by the second telescopic rod, so that the mounting plate and rubber pad move into the movable groove on the same side, and the rubber pad contacts the toothed block installed on the side wall of the support rod on the same side. Under the driving force of the second telescopic rod on the same side, the rubber pad is in close contact with the toothed block on the same side and deforms, so that the rubber pad and the toothed block are in a locked state, thereby playing the role of restricting and fixing the support rod. This helps to prevent the support rod and clamping plate from moving under the elastic force of the spring on the same side due to vibration or other reasons, which is conducive to maintaining the clamping effect of the equipment on the product.
[0011] Furthermore, two symmetrically distributed sliders are fixedly installed on the opposite sidewalls of the two support rods, and the inner walls of the two movable slots are provided with grooves that match the sliders on the same side.
[0012] By adopting the above technical solution, when the support rod slides in the same side movable groove, the support rod, along with the slider, slides in the same side sliding groove. The cooperation between the slider and the sliding groove helps to prevent the support rod from leaving the same side movable groove.
[0013] Furthermore, the lifting assembly includes a connecting frame fixedly installed on the top of the mounting frame, a sleeve provided above the mounting frame, a lifting rod slidably installed inside the sleeve, the bottom end of the lifting rod being fixedly connected to the top end of the connecting frame, and a first telescopic rod fixedly installed on the inner wall of the top end of the sleeve, the end of the first telescopic rod being fixedly connected to the top end of the lifting rod.
[0014] By adopting the above technical solution, the sleeve and the mounting point in the prior art are fixed by a flange, and then the bottom part is raised and lowered by the first telescopic rod driving the lifting rod, thereby adjusting the height of the product and facilitating subsequent processing.
[0015] Furthermore, two symmetrically distributed limiting grooves are provided on both sides of the mounting frame, and limiting blocks are slidably installed in each limiting groove. The two limiting blocks on the same side and the opposite side of the support block on the same side are fixed by the first bolt. Two symmetrically distributed positioning blocks are fixedly installed on the side of the limiting block near the support block on the same side. The side wall of the support block is provided with positioning grooves that match the positioning blocks on the same side.
[0016] By adopting the above technical solution, when the support block slides within the mounting frame, the support block, along with the limiting block, slides within the limiting groove on the same side. The cooperation between the limiting block and the limiting groove helps to restrict and stabilize the support block, which is beneficial to maintaining the stability of the support block's movement. Furthermore, a positioning block is provided on the inner side of the limiting block. The positioning block engages with the positioning groove opened on the side wall of the support block, which helps to restrict the positioning and limiting block, making it easier to fix it with the first bolt later.
[0017] Furthermore, each of the two mounting blocks has an assembly groove at its top that matches the bottom of the support block on the same side. Two symmetrically distributed inserts are fixedly installed on the inner walls of both sides of the two assembly grooves. The side walls of the two support blocks have slots that match the inserts on the same side.
[0018] By adopting the above technical solution, an assembly groove is provided at the top of the mounting block. The assembly groove at the top of the mounting block engages with the bottom of the support block. The inner wall of the assembly groove is provided with an insert block, which engages with the slot on the side wall of the support block to limit and position the mounting block, making it easier to fix it with a second bolt later.
[0019] In summary, this utility model has the following beneficial technical effects:
[0020] (1) In this utility model, by setting up a pressure detection component, the support block, the mounting block and the clamping plate are moved synchronously by the dual-axis cylinder to clamp and fix the product. A support column, a support rod and a spring are provided between the clamping plate and the mounting block on the same side, which can play a buffering role. A pressure sensor is provided in the support column. When the clamping plate contacts the product, the clamping plate pushes the support rod to slide in the movable groove on the same side under the pushing force of the dual-axis cylinder, thereby causing the spring on the same side to contract and the support rod to contact the pressure sensor on the same side, which plays a role in detecting the magnitude of the clamping force. This helps to avoid damage to the product due to excessive clamping force, thereby improving the clamping effect of the equipment.
[0021] (2) In this utility model, by setting up the lifting component, the sleeve and the installation point in the prior art are fixed by the flange, and then the lifting rod is driven by the first telescopic rod to drive the bottom part to rise and fall, thereby playing the role of adjusting the product height and facilitating subsequent processing.

[0033] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.
[0034] Please see Figure 1-6 A pull-out anodizing clamping fixture includes a mounting frame 1. Two symmetrically distributed support blocks 10 are slidably installed inside the mounting frame 1. A dual-axis cylinder 14 is provided on the inner wall of the top of the mounting frame 1. The piston shaft end of the dual-axis cylinder 14 is fixedly connected to the opposite side of the support block 10 on the same side. Mounting blocks 2 are provided at the bottom of the two support blocks 10. Clamping plates 5 are provided on opposite sides of the two mounting blocks 2. A pressure detection assembly is provided between the mounting blocks 2 and the clamping plates 5 on the same side. The pressure detection assembly includes a support column 3 fixedly installed on the opposite side of the two mounting blocks 2. Movable grooves 21 are opened on the opposite side of the two support columns 3. Support rods 4 are slidably installed in the two movable grooves 21. One end of the two support rods 4 is fixedly connected to the opposite side of the clamping plate 5 on the same side. Springs 20 are fixedly connected between the opposite ends of the two support rods 4 and the inner wall of the opposite side of the movable groove 21 on the same side. Pressure sensors 19 are provided on the inner wall of the opposite side of the two movable grooves 21.
[0035] When in use, the device can be driven by a dual-axis cylinder 14 to slide two support blocks 10 within the mounting frame 1. The support blocks 10 move synchronously with the mounting block 2 and clamping plate 5 on the same side, so that the clamping plate 5 contacts the opposite side of the product, thus clamping and fixing the product. After the clamping plate 5 contacts the opposite side of the product, the clamping plate 5 pushes the support rod 4 to slide within the movable groove 21 on the same side under the pushing force of the dual-axis cylinder 14, thereby causing the spring 20 on the same side to contract, which can play a buffering role. The support rod 4 contacts the pressure sensor 19 on the same side, which can detect the magnitude of the clamping force, helping to avoid damage to the product due to excessive clamping force, thus improving the clamping effect of the device.
[0036] Both support rods 4 have fixing components on their side walls. These components include mounting cylinders 6 fixedly installed on the side walls of the two support columns 3. The bottom ends of both mounting cylinders 6 extend into the movable grooves 21 on the same side. Second telescopic rods 18 are fixedly installed on the inner walls of the tops of both mounting cylinders 6. Mounting plates are fixedly installed at the ends of both second telescopic rods 18. Rubber pads are fixedly installed at the bottom ends of both mounting plates. Grooves 16 are formed on the side walls of both support rods 4. Multiple toothed blocks 17 arranged in a linear array are fixedly installed on the inner walls of the bottom ends of both grooves 16. The toothed blocks 17 in the same group are located below the mounting plates on the same side. Once the product is stably clamped, it can be moved... The second telescopic rod 18 drives the mounting plate and rubber pad on the same side to descend synchronously, moving them into the movable groove 21 on the same side. This causes the rubber pad to contact the toothed block 17 mounted on the side wall of the support rod 4 on the same side. Under the driving force of the second telescopic rod 18 on the same side, the rubber pad makes close contact with the toothed block 17 and deforms, causing the rubber pad to engage with the toothed block 17. This helps to restrict and fix the support rod 4, preventing the support rod 4 and clamping plate 5 from moving due to vibration or other reasons under the elastic force of the spring 20 on the same side. This helps to maintain the clamping effect of the equipment on the product.
[0037] Two symmetrically distributed sliders are fixedly installed on the opposite side walls of the two support rods 4. The inner walls of the two movable grooves 21 are provided with sliding grooves that match the sliders on the same side. When the support rod 4 slides in the movable groove 21 on the same side, the support rod 4 slides in the sliding groove on the same side with the slider. The cooperation between the slider and the sliding groove helps to prevent the support rod 4 from leaving the movable groove 21 on the same side.
[0038] Two symmetrically distributed limiting grooves 12 are provided on both sides of the mounting frame 1. Limiting blocks 11 are slidably installed in each limiting groove 12. The two limiting blocks 11 on the same side and the opposite side of the support block 10 on the same side are fixed by the first bolt. Two symmetrically distributed positioning blocks 23 are fixedly installed on the side of the limiting block 11 near the support block 10 on the same side. The side wall of the support block 10 is provided with a positioning groove that matches the positioning block 23 on the same side. When the support block 10 slides in the mounting frame 1, the support block 10 slides in the limiting groove 12 on the same side with the limiting block 11. The cooperation of the limiting block 11 and the limiting groove 12 plays a role in restricting and stabilizing the support block 10, which helps to maintain the stability of the movement of the support block 10. The positioning block 23 is provided on the inner side of the limiting block 11. The positioning block 23 engages with the positioning groove on the side wall of the support block 10 to restrict and position the limiting block 11, which is convenient for subsequent fixing with the first bolt.
[0039] The top of the mounting frame 1 is equipped with a lifting assembly, which includes a connecting frame 7 fixedly installed on the top of the mounting frame 1. A sleeve 9 is provided above the mounting frame 1, and a lifting rod 8 is slidably installed inside the sleeve 9. The bottom end of the lifting rod 8 is fixedly connected to the top end of the connecting frame 7. A first telescopic rod 13 is fixedly installed on the inner wall of the top end of the sleeve 9. The end of the first telescopic rod 13 is fixedly connected to the top end of the lifting rod 8. The sleeve 9 and the mounting point in the prior art are fixed by a flange. Then, the lifting rod 8 is driven by the first telescopic rod 13 to drive the bottom parts to rise and fall, thereby adjusting the height of the product and facilitating subsequent processing.
[0040] Both mounting blocks 2 have an assembly groove 15 at their top ends that matches the bottom end of the support block 10 on the same side. Two symmetrically distributed inserts 22 are fixedly installed on the inner walls of both sides of the assembly groove 15. The side walls of the two support blocks 10 have slots that match the inserts 22 on the same side. The mounting block 2 has an assembly groove 15 at its top end. The mounting block 2 engages with the bottom of the support block 10 through the assembly groove 15 at its top end. The inner wall of the assembly groove 15 has inserts 22 that engage with the slots on the side walls of the support block 10 through the inserts 22. This serves to limit and position the mounting block 2, making it easier to fix it with the second bolt later.
[0041] The implementation principle of this utility model embodiment is as follows: When the device is in use, the two support blocks 10 can be driven by the dual-axis cylinder 14 to slide within the mounting frame 1. The support blocks 10 move synchronously with the mounting block 2 and clamping plate 5 on the same side, so that the clamping plate 5 contacts the opposite side of the product, thereby clamping and fixing the product. A pressure detection component is provided between the clamping plate 5 and the mounting block 2 on the same side. By setting a constant pressure value, when the clamping plate 5 contacts the product, the clamping plate 5 acts on the pressure detection component on the same side under the push of the dual-axis cylinder 14. The pressure detection component tests the pressure value on the product. When the preset constant value is reached, the operation of the dual-axis cylinder 14 can be stopped, thereby achieving the effect of protecting the product. This helps to prevent the product from being damaged due to excessive clamping force and also helps to prevent the product from falling due to insufficient clamping force. A lifting component is provided at the top of the mounting frame 1 to adjust the height of the product, which facilitates the subsequent processing of the product in the electrolyte.
[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
