Description

Technical fields:

[0001] This utility model relates to the field of testing fixture technology, and specifically to a lifting device for edge testing. Background technology:

[0002] In modern industrial production, the quality requirements for products are becoming increasingly stringent, making pre-shipment inspection particularly important. Some products (such as aluminum tubes) require being lifted during inspection to ensure accurate testing.

[0003] In the past, measuring instruments needed to be moved up and down manually. This manual method had the following disadvantages: 1. The measured data fluctuated greatly, requiring repeated testing; 2. Hands easily became fatigued from prolonged up-and-down movement. Later, some manufacturers adopted lifting devices to replace manual lifting.

[0004] Currently available testing equipment uses lifting devices to lift products for testing. For example, Chinese utility model patent application CN215088963 U discloses an automatic screening and testing device, which includes: a testing equipment fixing bracket; a guide plate; a lifting cylinder; and a rotating cylinder, which is installed on the right side of the distribution plate. Its V-shaped structure for the part to be tested can accommodate parts of different sizes, thus allowing for the lifting of parts of varying thicknesses without needing to change the part to be tested, thereby securing the parts. Rubber protective pads protect the parts to be tested, preventing collisions and damage.

[0005] However, this existing automatic screening and inspection equipment limits the parts to be tested by a bracket and adjusts the bracket by lifting a cylinder. However, when inspecting products with high precision requirements, it is difficult to control the measurement force and it is easy to cause damage. In addition, the overall structure of this technical solution is not simple enough, the cost is not low enough, a certain amount of upfront investment is required, and the durability of the device is poor.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

The lifting mechanism includes a first bracket, a second bracket hinged to the first bracket, and a screw structure disposed on the lifting plate for adjusting the lifting of the lifting plate. One end of the first bracket is hinged to the lifting plate, and the other end of the first bracket is slidably disposed in a groove. One end of the second bracket is hinged to the support plate, and the other end of the second bracket is connected to the screw structure and can be driven by the screw structure to swing, thereby driving the lifting plate to rise / fall.

[0009] Furthermore, in the above technical solution, the screw structure includes a limiting block fixed to the lifting pad by a first screw, a slider that is movable back and forth on the limiting block and connected to the second bracket, a screw that passes through the limiting block and through the slider, and a nut that is disposed in the slider and used to match the screw.

A limiting pin is inserted into the limiting insertion hole, and the limiting pin extends into the first limiting hole and cooperates with the limiting annular groove to axially limit the screw.

[0012] Furthermore, in the above technical solution, one end of the lifting pad is fixedly installed with an upper swing positioning block for connecting with the first bracket; one end of the support pad is fixedly installed with a lower swing positioning block for connecting with the second bracket, and the other end of the support pad is fixedly installed with a sliding groove positioning block for slidably connecting with the first bracket, with the sliding groove provided on the sliding groove positioning block.

[0020] Figure 3 This is a cross-sectional schematic diagram of the screw structure in this utility model; Detailed implementation method:

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] See Figures 1 to 3 As shown, a lifting device for edge detection includes: a support plate 1, a lifting plate 2 that can be lifted and moved relative to the support plate 1 and used to place products, and a lifting mechanism 3 disposed between the support plate 1 and the lifting plate 2. The lifting mechanism 3 includes a first bracket 31, a second bracket 32 ​​hinged to the first bracket 31, and a screw structure 33 disposed on the lifting plate 2 and used to adjust the lifting of the lifting plate 2. One end of the first bracket 31 is hinged to the lifting plate 2, and the other end of the first bracket 31 is slidably disposed in a slide groove 101. One end of the second bracket 32 ​​is hinged to the support plate 1, and the other end of the second bracket 32 ​​is connected to the screw structure 33 and can be driven by the screw structure 33 to swing, thereby driving the lifting plate 2 to rise / fall.

[0023] This invention changes the traditional method of using a cylinder to drive the support. Instead, the screw structure 33 of the lifting mechanism 3 drives the first support 31 and the second support 32 to retract / open, thereby adjusting the lifting pad 2. This significantly improves the stability during the lifting process, allows for precise control of the measuring force, and is suitable for testing products with high accuracy requirements. It is also suitable for widespread application in various testing lifting devices. Furthermore, compared to existing structures, this invention eliminates the need for manual lifting. Simply place the product on the lifting pad 2, and the screw structure 33 drives the product up and down to the appropriate position, providing better measuring force. The structure is very simple, low-cost, stable, reliable, and highly convenient to use.

[0024] The screw structure 33 includes a limiting block 331 fixed to the lifting pad 2 by a first screw 310, a slider 332 that is movable back and forth on the limiting block 331 and connected to the second bracket 32, a screw 333 that passes through the limiting block 331 and through the slider 332, and a nut 334 that is set in the slider 332 and used to match the screw 333. Here, the screw structure 33 drives the lifting pad 2 to adjust its height by rotating the screw 333. Specifically, when the screw 333 is twisted, the nut 334 has an internal thread on its inner wall and an external thread on its outer wall, causing the nut 334 to move along the axial direction of the screw 333, thereby driving the slider 332 to slide. Furthermore, the slider 332 drives the second bracket 32 ​​to retract / open. Since the second bracket 32 ​​is hinged to the first bracket 31 and the lower end of the first bracket 31 is connected to the slide groove 101, it also drives the first bracket 31 to retract / open, thereby driving the lifting pad 2 to rise / fall.

[0025] The limiting block 331 has a limiting groove 335 for the slider 332 to slide back and forth. The limiting block 331 also has a first screw hole 336. Correspondingly, the lifting pad 2 has a first through hole 21, through which the first screw 310 passes and is installed in the first screw hole 336. The slider 332 has a recessed nut positioning groove 337 for positioning the nut 334. The slider 332 also has a slider positioning hole 338 for connecting to the second bracket 32. The limiting block 331 has a second through hole 339 for the screw 333 to pass through, and a first limiting hole 3311 for axially limiting the screw 333. Here, the limiting groove 335 effectively limits the slider 332, preventing it from coming out. The nut 334 is fixed in the nut positioning groove 337, allowing the nut 334 to move synchronously with the slider 332.

[0026] One end of the screw 333 that extends into the first limiting hole 3311 is recessed to form a limiting annular groove 3331. The limiting block 331 has a limiting insertion hole 3312 below the first limiting hole 3311 that communicates with the first limiting hole 3311. A limiting pin 3313 is inserted into the limiting insertion hole 3312. The limiting pin 3313 extends into the first limiting hole 3311 and engages with the limiting annular groove 3331 to axially limit the screw 333. Here, the limiting pin 3313 is used to axially limit the screw 333 to prevent the screw 333 from coming out of the first limiting hole 3311, while not affecting the circumferential rotation of the screw 333.

[0027] In one embodiment of the present invention, preferably, one end of the lifting pad 2 is fixedly installed with an upper swing positioning block 22 for connecting with the first bracket 31; one end of the support pad 1 is fixedly installed with a lower swing positioning block 12 for connecting with the second bracket 32, and the other end of the support pad 1 is fixedly installed with a sliding groove positioning block 13 for slidably connecting with the first bracket 31, and the sliding groove 101 is disposed on the sliding groove positioning block 13.

[0028] The lower helix positioning block 12 has a lower helix positioning hole 12, and the second bracket 32 ​​is provided with a lower helix positioning pin 322 for insertion into the lower helix positioning hole 12. The second bracket 32 ​​is also provided with a slider positioning pin 321 that can be slidably inserted into the slider positioning hole 338. The upper helix positioning block 22 has an upper helix positioning hole 22, and the first bracket 31 is provided with an upper helix positioning pin 311 for insertion into the upper helix positioning hole 22. The first bracket 31 is also provided with a slide groove positioning pin 312 that can be slidably inserted into the slide groove 101.

[0029] The sliding groove positioning block 13 is installed on the support plate 1 by a second screw 320. The support plate 1 has a second through hole 16 for the second screw 320 to pass through, and the sliding groove positioning block 13 has a second screw hole 132 for the second screw 320 to be installed. The lower hem positioning block 12 is installed on the support plate 1 by a third screw 330. The support plate 1 has a third through hole 17 for the third screw 330 to pass through, and the lower hem positioning block 12 has a third screw hole 123 for the third screw 330 to be installed.

[0030] The upper swing positioning block 22 is installed on the lifting pad 2 by the fourth screw 340. The lifting pad 2 has a fourth through hole 18 for the fourth screw 340 to pass through, and the upper swing positioning block 22 has a fourth screw hole 222 for the fourth screw 340 to be installed.

[0031] The first support 31 has a blocking portion 315 formed on it for abutting against the second support 32 to prevent excessive descent / ascent. Here, when the first support 31 and the second support 32 swing to the lowest / highest position, the blocking portion 315 abuts against the first support 31 to form a blockage.

[0032] In summary, this invention changes the traditional method of using a cylinder to drive the bracket. Instead, the screw structure 33 of the lifting mechanism 3 drives the first support 31 and the second support 32 to retract / open, thereby adjusting the lifting pad 2. This significantly improves the stability during the lifting process, allows for precise control of the measuring force, and is suitable for testing products with high accuracy requirements. It is also suitable for widespread application in various testing lifting devices. Furthermore, compared to existing structures, this invention eliminates the need for manual lifting. The product is simply placed on the lifting pad 2, and the screw structure 33 drives the product up and down to the appropriate position, providing better measuring force. The structure is very simple, low-cost, stable, reliable, and highly convenient to use.
