[0037] like Figures 1 to 5 The embodiment of the present utility model provides a fixture for detecting the shape and position of the top surface of a radiator, comprising a positioning platform 1, a fixture frame 2, a fixture plate 3 and a driving member 5;

[0038] The positioning platform 1 is used to place the product 6 to be tested, with the test hole 61 of the product 6 facing upwards;

[0039] The fixture frame 2 is located above the positioning platform 1;

[0040] The fixture plate 3 is slidably mounted on the fixture frame 2 in the vertical direction, and a detection portion 4 is provided at the bottom thereof for detecting the hole position of the hole 61 to be detected;

[0041] The driving member 5 is mounted on the fixture frame 2 and connected to the fixture plate 3 , and is used to drive the fixture plate 3 to slide down and enable the detection portion 4 to reach the hole to be detected 61 .

[0042] In this embodiment, the main function of the positioning platform 1 is to provide a stable platform for placing the product to be tested. The design of the positioning platform 1 ensures that the test hole 61 of the product to be tested 6 can be accurately oriented upwards to facilitate subsequent testing work.

[0043] In this embodiment, the jig frame 2 is located above the positioning table 1. Its primary function is to provide reliable support and guidance for the jig plate 3. The jig frame 2 is designed with strength and stability in mind to ensure smooth and accurate sliding of the jig plate 3 during testing. The jig frame 2 is typically made of high-strength materials to withstand the wear and pressure of long-term use.

[0044] In this embodiment, the fixture plate 3 is a key component that is slidably mounted on the fixture frame 2 along the vertical direction; a detection portion 4 is provided at its bottom for performing hole position detection on the hole 61 to be measured.

[0045] In this embodiment, the driving member 5 is mounted on the fixture frame 2 and connected to the fixture plate 3. Its main function is to drive the fixture plate 3 to slide down in the vertical direction so that the detection part 4 can smoothly reach the position of the hole 61 to be detected.

[0046] Based on this, when inspecting the machining position of the hole 61 to be tested on the product 6 (i.e., the top plate of the radiator), the product 6 to be tested is placed on the positioning table 1, and then the driving member 5 drives the jig plate 3 to slide down, driving the inspection unit 4 to reach the hole 61 to be tested. The inspection unit 4 inspects the machining position of the hole 61 to determine the machining accuracy of the hole 61 to be tested. This replaces the manual operation of hole alignment and has the advantage of more convenient and faster hole position inspection.

[0047] In one embodiment, the detection part 4 includes a mounting plate 41 and at least one telescopic column 42. The mounting plate 41 is installed at the bottom of the fixture plate 3, and the telescopic column 42 is installed at the bottom of the mounting plate 41. The distribution position of each telescopic column 42 corresponds one-to-one to the distribution position of each hole 61 to be tested of the product 6 to be tested in the vertical direction.

[0048] In this embodiment, the detection part 4 mainly includes a mounting plate 41 and at least one telescopic column 42. Specifically, the mounting plate 41 is designed to be installed at the bottom position of the jig plate 3. The telescopic columns 42 are arranged at the bottom of the mounting plate 41, and their distribution positions are completely corresponding to the positions of the various holes to be tested 61 of the product to be tested 6 in the vertical direction. Such a design ensures that each telescopic column 42 can be accurately aligned with the hole to be tested 61, so that during the detection process, it is possible to accurately measure whether the processing position of each hole to be tested 61 is accurate. Through this one-to-one correspondence, the accuracy and efficiency of the detection can be effectively improved, ensuring that each hole to be tested 61 can be accurately detected, thereby ensuring the reliability and accuracy of the entire detection process.

[0049] In one embodiment, a pressure sensor 421 is provided in the telescopic column 42 . The pressure sensor 421 is configured to be triggered and output a stop detection signal when the telescopic column 42 contracts.

[0050] In this embodiment, the telescopic column 42 is designed to be inserted into the corresponding hole 61 to be tested. When the detection part 4 slides down and drives each telescopic column 42 to be inserted into the corresponding hole 61 to be tested; if the processing position of the hole 61 to be tested is accurate, the corresponding telescopic column 42 can be inserted normally (refer to Figure 2 If the processing position of the hole 61 to be measured deviates, that is, the hole 61 to be measured is offset, the corresponding telescopic column 42 cannot be completely aligned with the hole 61 to be measured in the vertical direction, which will cause the telescopic column 42 to contact the surface of the product 6 to be measured, thereby causing the telescopic column 42 to contract. The pressure sensor 421 in the telescopic column 42 will be triggered, sending a stop detection signal, and indicating that the processing position of the hole 61 to be measured is inaccurate (refer to Figure 3 The telescopic column 42 is in the middle position.

[0051] In this embodiment, the use of the pressure sensor 421 for alarm design has higher accuracy than relying on manual visual inspection.

[0052] In one embodiment, the telescopic column 42 includes a fixed column 422, a sliding column 423 and a compression spring 424. The upper end of the fixed column 422 is fixedly mounted on the mounting plate 41, the sliding column 423 is slidably connected to the fixed column 422, and the compression spring 424 is located between the sliding column 423 and the fixed column 422. The sliding column 423 is used to slide toward the fixed column 422 to compress the compression spring 424 when it is subjected to vertical upward resistance, and trigger the pressure sensor 421.

[0053] In this embodiment, the design of telescopic column 42 includes several key components to ensure its functionality and reliability. Specifically, telescopic column 42 consists of three main parts: a fixed column 422, a sliding column 423, and a compression spring 424. The upper end of fixed column 422 is securely mounted to the bottom of mounting plate 41; sliding column 423 is designed to slide along fixed column 422, allowing it to slide toward fixed column 422 (i.e., upward) when encountering vertical upward resistance.

[0054] In this embodiment, to ensure smooth sliding of the sliding post 423 and provide the necessary elastic support, a compression spring 424 is cleverly positioned between the sliding post 423 and the fixed post 422. When the sliding post 423 encounters vertical upward resistance, it slides upward along the fixed post 422, compressing the compression spring 424 between it and the fixed post 422 and triggering the pressure sensor 421 to issue a stop detection signal. The compressed compression spring 424 generates a rebound force that drives the sliding post 423 downward and back to its original position after the detection is complete.

[0055] In one embodiment, a sliding cavity is formed at the upper end of the sliding column 423 and is sleeved on the outer wall of the lower end of the fixed column 422. The pressure sensor 421 is installed at the lower end of the fixed column 422. A protrusion is provided at the bottom of the sliding cavity. One end of the compression spring 424 is sleeved on the outer wall of the lower end of the fixed column 422, and the other end of the compression spring 424 is sleeved on the protrusion.

[0056] In this embodiment, a sliding cavity is specially designed and opened at the upper end of the sliding column 423. The size and shape of this sliding cavity are just suitable for being fitted on the lower outer wall of the fixed column 422. This design allows the sliding column 423 to slide freely on the lower outer wall of the fixed column 422, thereby realizing its function. At the same time, a pressure sensor 421 is installed at the lower end of the fixed column 422. The function of this pressure sensor 421 is to monitor and record the pressure changes acting on the lower end of the fixed column 422 in real time. It can be understood that when the sliding column 423 is subjected to vertical upward resistance, the sliding column 423 contracts upward relative to the fixed column 422 and compresses the compression spring 424, so that the protrusion in the sliding cavity presses upward against the pressure sensor 421, thereby triggering the pressure sensor 421 to send a stop detection signal.

[0057] In one embodiment, the detection portion 4 is detachably mounted on the fixture plate 3 .

[0058] In this embodiment, the positions and numbers of the holes 61 to be tested on different products to be tested 6 are different. In order to be compatible with the hole position detection of more types of products to be tested 6, corresponding detection parts 4 can be pre-adapted for different types of products to be tested 6; in this way, the adapted detection parts 4 can be replaced on the jig plate 3 for detection according to the different products to be tested 6.

[0059] In one embodiment, the jig frame 2 is provided with a guide member 21 , and the jig plate 3 is provided with a guide portion 31 . The jig plate 3 is slidably connected to the guide member 21 along a vertical direction via the guide portion 31 .

[0060] In this embodiment, the guide member 21 includes a plurality of guide rods, and the guide portion 31 includes a plurality of through holes formed on the fixture plate 3 . The plurality of through holes of the guide portion 31 are respectively sleeved on the plurality of guide rods.

[0061] In one embodiment, the jig frame 2 is provided with a guide member 21 , and the jig plate 3 is provided with a guide portion 31 . The jig plate 3 is slidably connected to the guide member 21 along a vertical direction via the guide portion 31 .

[0062] In this embodiment, the guide member 21 is used to ensure that the jig plate 3 can slide smoothly and accurately in the vertical direction. Accordingly, the jig plate 3 is equipped with a dedicated guide portion 31, which is connected to the guide member 21, so that the jig plate 3 can slide stably in the vertical direction.

[0063] In one embodiment, the guide member 21 includes a plurality of guide rods, and the guide portion 31 includes a plurality of through holes formed on the fixture plate 3 . The plurality of through holes of the guide portion 31 are respectively sleeved on the plurality of guide rods.

[0064] In this embodiment, the guide member 21 specifically comprises a plurality of guide rods, which are evenly distributed at appropriate locations (e.g., the edges) of the jig frame 2 to ensure stability and guiding accuracy of the jig plate 3 during sliding. The guide portion 31 on the jig plate 3 is comprised of a plurality of through holes, which are evenly distributed at corresponding locations (e.g., the edges) of the jig plate 3. By fitting these through holes onto the plurality of guide rods, the jig plate 3 can slide smoothly along the guide rods, thereby achieving precise vertical positioning and movement.

[0065] In one embodiment, a positioning portion is provided on the positioning platform 1 , and the positioning portion is used to position the product to be tested 6 placed on the positioning platform 1 so that the product to be tested 6 is located at an accurate testing position.

[0066] In this embodiment, a specially designed positioning unit is installed on positioning platform 1. The primary function of this positioning unit is to ensure that the product under test 6 placed on positioning platform 1 is precisely positioned. In this way, the product under test 6 can be accurately placed in the predetermined testing position, thereby ensuring the accuracy and reliability of the testing process.

[0067] In one embodiment, the driving member 5 is a screw motor structure or a telescopic cylinder 51 structure. In this embodiment, the structure of the cylinder 51 and the telescopic rod 52 is preferably used as the driving structure.
