Description

Technical Field

[0001] This utility model relates to the field of needle roller testing, and in particular to a needle roller height testing device. Background Technology

[0002] In the bearing manufacturing process, the height accuracy of bearing needle rollers plays a crucial role in the bearing's performance and service life. Currently, the height testing of bearing needle rollers often employs a horizontal conveyor combined with a swing-type stop. The stop activates upon contact with a defective product, causing an abnormal height and thus measuring the needle roller height. This method can lead to imbalances and increased noise in the assembled bearing during operation, potentially shortening its lifespan, increasing equipment maintenance costs, and ultimately impacting the product quality and economic efficiency of the entire supply chain. Therefore, there is an urgent need for a more accurate and reliable bearing needle roller height testing device to effectively address the shortcomings of existing testing methods and improve bearing production quality and efficiency.

[0003] When two defective products appear side-by-side during horizontal transport, the swing-type stop lever can only detect the first defective product. This is because after contacting the first defective product, the lever will react due to the product's abnormal height, preventing it from promptly and accurately detecting the second defective product that follows. This situation significantly reduces the accuracy and reliability of the detection, potentially causing some defective products to be mixed into batches of qualified products, posing serious risks to subsequent bearing assembly and product quality. Utility Model Content

[0004] To overcome the problem that existing needle roller height testing devices, due to their swing-type testing method, often only test the first non-conforming product when encountering two non-conforming products, making it difficult to test the second one immediately following, thus causing some non-conforming products to be mixed into the batch of qualified products.

[0005] The technical solution of this utility model is: a needle roller height testing device, including a positioning component, a testing component connected to the positioning component, a supplementary testing component movably connected to the positioning component, and a conveying component connected to the rear end of the positioning component;

[0006] The positioning assembly includes a positioning plate connected to the test assembly, a hydraulic push rod connected to the positioning plate, and a fixed base plate connected to the hydraulic push rod.

[0007] The test assembly includes a fixed block connected to the upper end of the positioning plate, a rotating rod movably connected to the fixed block, a rotation counter connected to one end of the rotating rod, a connector connected to the other end of the rotating rod, and a toggle bar connected to the connector.

[0008] The supplementary measurement assembly includes a connecting frame movably connected to a fixed base plate, an infrared ranging sensor connected to the connecting frame, a combined piece connected to the lower end of the connecting frame, connecting pieces respectively connected to the combined piece and the connecting frame, a positioning rod movably connected to the connecting piece, a pressure plate connected to the positioning rod, a return spring connected to the pressure plate and the connecting piece, and an electric push rod connected to the lower end of the combined piece.

[0009] Preferably, the rotation counter is connected to the positioning plate, the connecting frame is configured in an inverted "L" shape, the pressure plate is movably connected to the connecting frame, and the pressure plate is movably connected to the assembly plate.

[0010] Preferably, the positioning component further includes a limiting strip connected to the fixed base plate, a fixed baffle connected to the upper end of the limiting strip, and a connecting rib plate connected to the lower end surface of the fixed base plate, wherein the limiting strip is movably connected to the positioning plate.

[0011] Preferably, the supplementary testing component also includes a combination frame connected to the electric push rod, the combination frame being connected to the fixed base plate and movably connected to the combination piece.

[0012] Preferably, the conveying assembly includes a connecting wheel frame connected to the rear end of the connecting stiffener plate, a rotating wheel movably connected to the connecting wheel frame, a transmission belt movably connected to the rotating wheel, a clamping sleeve connected to the transmission belt, a positioning strip connected to the inner wall of the clamping sleeve, and a servo motor connected to the rotating wheel closest to the hydraulic push rod.

[0013] Preferably, there are several rotating wheels, which are rotatably connected to the transmission belt; there are several clamping sleeves, and the positioning strips and clamping sleeves are configured to correspond one-to-one.

[0014] Preferably, the rear end of the connecting wheel frame is connected to a unified component, which includes a fixed box connected to the rear end of the connecting wheel frame, two guide slots opened on the fixed box, an air outlet pipe and an air inlet pipe connected to one side of the fixed box, a first air pipe connected to the air outlet pipe, an electric air pump connected to the first air pipe, and a second air pipe connected to the electric air pump, wherein the second air pipe is connected to the air inlet pipe.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses an electric push rod to drive the combined piece to move in the vertical direction. After the rotating rod deflects, it can withstand the pressure of the needle roller during the conveying process through the pressure plate, so as to drive the pressure plate to slide on the connecting frame, thereby changing the degree of the infrared ranging sensor, thus realizing the detection of non-conforming products.

[0017] 2. This utility model uses an electric air pump to draw air from the upper part of the fixed box through the first air pipe, and then uses the second air pipe to transport the drawn air to the lower part of the fixed box. The air is then fully adsorbed by the guide groove on the fixed box or pushed away from the clamping sleeve, thereby realizing the height detection and separation of the roller needles.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] A needle roller height testing device, based on Figures 1-5As shown, it includes a positioning component 1, a test component 2 connected to the positioning component 1, a supplementary test component 3 actively connected to the positioning component 1, and a conveying component 4 connected to the rear end of the positioning component 1.

[0026] The positioning component 1 includes a positioning plate 103 connected to the test component 2, a hydraulic push rod 102 connected to the positioning plate 103, and a fixed base plate 101 connected to the hydraulic push rod 102;

[0027] Test component 2 includes a fixed block 201 connected to the upper end of the positioning plate 103, a rotating rod 202 movably connected to the fixed block 201, a rotation counter 203 connected to one end of the rotating rod 202, a connector 204 connected to the other end of the rotating rod 202, and a toggle bar 205 connected to the connector 204.

[0028] The supplementary testing component 3 includes a connecting frame 304 movably connected to the fixed base plate 101, an infrared ranging sensor 305 connected to the connecting frame 304, a combination piece 303 connected to the lower end of the connecting frame 304, a connecting piece 306 connected to the combination piece 303 and the connecting frame 304 respectively, a positioning rod 307 movably connected to the connecting piece 306, a pressure plate 309 connected to the positioning rod 307, a return spring 308 connected to the pressure plate 309 and the connecting piece 306, and an electric push rod 302 connected to the lower end of the combination piece 303.

[0029] It should be noted that the positioning plate 103 is moved vertically by the hydraulic push rod 102, and the positioning plate 103 and the fixed base plate 101 clamp the needle rollers. At the same time, the needle rollers of the non-conforming products push the actuating bar 205, so that the actuating bar 205 pushes the rotating rod 202 to rotate. The rotating rod 202 triggers the rotation counter 203 to count the non-conforming products.

[0030] according to Figure 1 and Figure 2 As shown, the rotation counter 203 is connected to the positioning plate 103, the connecting frame 304 is set in an inverted "L" shape, the pressure plate 309 is movably connected to the connecting frame 304, and the pressure plate 309 is movably connected to the assembly plate 303.

[0031] according to Figure 1 and Figure 3 As shown, the positioning component 1 also includes a limiting strip 104 connected to the fixed base plate 101, a fixed baffle 105 connected to the upper end of the limiting strip 104, and a connecting rib plate 106 connected to the lower end surface of the fixed base plate 101. The limiting strip 104 is movably connected to the positioning plate 103.

[0032] It should be noted that the limiting strip 104 is used to assist the vertical movement of the positioning plate 103, and the fixed baffle 105 is used to prevent the positioning plate 103 from being excessively lifted.

[0033] according to Figure 2 As shown, the supplementary testing component 3 also includes a combination frame 301 connected to the electric push rod 302. The combination frame 301 is connected to the fixed base plate 101 and is movably connected to the combination piece 303.

[0034] according to Figure 4 As shown, the conveying assembly 4 includes a connecting wheel frame 401 connected to the rear end of the connecting stiffener 106, a rotating wheel 402 movably connected to the connecting wheel frame 401, a transmission belt 403 movably connected to the rotating wheel 402, a clamping sleeve 404 connected to the transmission belt 403, a positioning strip 405 connected to the inner wall of the clamping sleeve 404, and a servo motor 406 connected to the rotating wheel 402 closest to the hydraulic push rod 102.

[0035] It should be noted that the servo motor 406 drives the rotating wheel 402 to rotate, and the rotating wheel 402 drives the transmission belt 403 to rotate, which in turn drives the remaining rotating wheels 402 to rotate. This allows the several clamping sleeves 404 connected to the transmission belt 403 to move synchronously, thereby allowing the needle rollers connected to the clamping sleeves 404 to move and be conveyed synchronously.

[0036] according to Figure 4 As shown, there are several rotating wheels 402, which are rotatably connected to the transmission belt 403. There are several clamping sleeves 404, and the positioning strips 405 and clamping sleeves 404 are configured to correspond one-to-one.

[0037] according to Figure 5 As shown, the rear end of the connecting wheel frame 401 is connected to a unified component 5. The unified component 5 includes a fixed box 501 connected to the rear end of the connecting wheel frame 401, two guide slots 502 opened on the fixed box 501, an air outlet pipe 503 and an air inlet pipe 507 connected to one side of the fixed box 501, a first air pipe 504 connected to the air outlet pipe 503, an electric air pump 505 connected to the first air pipe 504, and a second air pipe 506 connected to the electric air pump 505. The second air pipe 506 is connected to the air inlet pipe 507.

[0038] It should be noted that the electric air pump 505 is used to draw air from the upper part of the fixed box 501 through the first air pipe 504, and the drawn air is transported to the lower part of the fixed box 501 through the second air pipe 506. The air is then fully adsorbed by the guide groove 502 on the fixed box 501 or pushed away from the clamping sleeve 404, thereby realizing the height detection and separation of the needle rollers.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
