Description

Technical Field

[0001] This invention relates to the field of barbell bar processing technology, and more specifically, to a testing device for barbell bar processing. Background Technology

[0002] Barbell bars are a common piece of fitness equipment, widely used in strength training and competitive sports. Their quality directly affects user safety and training effectiveness. During the manufacturing process of barbell bars, ensuring they meet standard requirements is a crucial step. Existing testing methods are mostly manual, which has the following main problems: manual testing typically requires lengthy periods of multiple measurements and calibrations, resulting in low efficiency, difficulty in meeting the demands of large-scale production, and low testing accuracy; manual operation is easily affected by the experience and skill level of personnel, leading to inaccurate test results and significant errors, making it impossible to guarantee the consistent quality of each barbell bar.

[0003] Chinese patent application CN110216171A discloses a curvature detector, comprising a support platform and reference blocks mounted on both sides of the support platform. The reference blocks are parallel to each other and on the same central axis. A contact rod is disposed in the middle of the support platform, and the contact rod is disposed on the central axis of the two reference blocks and moves along their central axis. A pressure block support frame is mounted above the support platform, and a pressure block is mounted on the pressure block support frame. The pressure block is located directly above the central axis of the two reference blocks and moves on the pressure block support frame in the direction of the central axis of the two reference blocks. This invention proposes a curvature detector to detect the curvature of steel pipes and straighten the curved parts.

[0004] To address the shortcomings of existing technologies, this invention provides a testing device for barbell bar processing to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a testing device for barbell bar processing.

[0006] To solve the above-mentioned technical problems, the present invention provides a testing device for barbell bar processing, comprising:

[0007] The device body has a detection port on one side and a feeding plate on one side.

[0008] The detection section is located in the middle of the detection port. The detection section includes a hydraulic rod fixed to the device body, a clamping part fixed to the bottom of the hydraulic rod, and a detection plate installed inside the clamping part. The detection plate can move left and right along the clamping part. A measuring gauge is installed on the top of the detection plate, and the top of the measuring gauge is in contact with the surface of the barbell bar.

[0009] The counterweight section is used to add weight to the barbell bar. When the detection section drives the barbell bar to move upward gradually, the counterweight section gradually increases the weight on both ends of the barbell bar.

[0010] Furthermore, the clamping part includes a clamping block and a limiting block. One side of the clamping block has a clamping opening facing the feeding plate. The bottom of the clamping opening has a first groove. The bottom of the first groove has a slot. The detection plate is installed in the slot.

[0011] Furthermore, a rack is provided at the bottom of the detection plate, an inner cavity is provided inside the clamping block, a motor is installed on one side of the clamping block, a gear is installed on one side of the motor, the gear is installed in the inner cavity, and the gear meshes with the rack.

[0012] Furthermore, a limiting groove is provided at the inner bottom of the clamping port, one side of the limiting block is hinged to the inner sidewall of the limiting groove, an insertion hole is provided at the bottom of the limiting groove, the insertion hole extends to the bottom of the clamping block, an adjusting rod is installed inside the insertion hole, a spring is sleeved on the adjusting rod, and a first magnetic block is provided at the bottom of the adjusting rod.

[0013] Furthermore, a plug rod is provided at the bottom of the device body, and a second magnetic block is installed at the top of the plug rod. When the clamping block moves downward, the plug rod can be inserted into the plug hole, and the first magnetic block and the second magnetic block attract each other.

[0014] Furthermore, the counterweight includes a counterweight groove formed at the top of the detection port. A first telescopic rod is fixed to the top of the counterweight groove, and a second telescopic rod is installed at the bottom of the first telescopic rod. A counterweight block is fixed to the bottom of the second telescopic rod, and the second telescopic rod can move up and down along the first telescopic rod.

[0015] Furthermore, the bottom of the counterweight is provided with an arc-shaped groove, and the counterweight gradually rises in the direction away from the clamping block.

[0016] Furthermore, a second groove is provided at the bottom of the detection port, and both ends of the detection plate extend into the second groove.

[0017] Furthermore, the inner wall of the second groove is provided with an inclined groove, through which the tested barbell rod is discharged.

[0018] The beneficial effects of this invention are:

[0019] 1. By simulating the stress on a barbell bar in actual use, the weight block's design ensures even weight distribution during testing, thus improving accuracy. The bottom of the weight block has an arc-shaped groove, allowing the barbell to contact and push the weight block upwards. Simultaneously, the weight block gradually increases the counterweight on both ends of the barbell as weight is applied, ensuring a more even and stable weight distribution during testing. This simulates the stress on the barbell bar in real-world use, ensuring the accuracy and reliability of the test results.

[0020] 2. The clamping part can be moved up and down by the hydraulic rod. When the bottom wall of the clamping port of the clamping block is at the same horizontal line as the bottom wall of the detection port, the barbell can enter the detection port. The measuring gauge is moved left and right by the detection plate to detect the bending degree of the bottom of the barbell. The probe at the top of the measuring gauge is always in contact with the surface of the barbell. Attached Figure Description

[0034] like Figure 1-6 As shown, a barbell bar processing inspection device of the present invention includes: a device body 1, a detection port 11 provided on one side of the device body 1, and a feeding plate 12 provided on one side of the device body 1; the feeding plate 12 is inclined, and the barbell bar enters the detection port 11 through the feeding plate 12 and is inspected at the detection port 11; and a detection part 2, located in the middle of the detection port 11. The detection part 2 includes a hydraulic rod 21 fixed on the device body 1, a clamping part 22 fixed to the bottom of the hydraulic rod 21, and a detection plate 23 installed inside the clamping part 22. The detection plate 23 can move left and right along the clamping part 22, and a measuring gauge 24 is installed on the top of the detection plate 23, with the top of the measuring gauge 24 in contact with the surface of the barbell bar.

[0035] The hydraulic rod 21 can drive the clamping part 22 to move up and down. When the bottom wall of the clamping port 29 of the clamping block 221 is at the same horizontal line as the bottom wall of the detection port 11, the barbell bar can enter the detection port 11. The detection plate 23 moves left and right to drive the measuring gauge 24 to detect the bending degree of the bottom of the barbell bar. The probe at the top of the measuring gauge 24 is always in contact with the surface of the barbell bar.

[0036] The clamping part 22 includes a clamping block 221 and a limiting block 222. A clamping opening 29 is provided on one side of the clamping block 221 facing the feeding plate 12. A first groove 223 is provided at the bottom of the clamping opening 29. A slot 224 is provided at the bottom of the first groove 223. The detection plate 23 is installed in the slot 224.

[0037] The clamping port 29 is used to accommodate and fix the barbell bar, keeping it stable and in the correct position during the test. The slot 224 is a specially designed embedded space for installing the test plate 23. The test plate 23 is installed in the slot 224 and can move left and right along the clamping part 22. During the test, the movement of the test plate 23 drives the measuring gauge 24 to detect the bending of the bottom of the barbell bar, ensuring that the probe at the top of the measuring gauge 24 is always in contact with the surface of the barbell bar, thereby obtaining accurate measurement data.

[0038] The bottom of the detection plate 23 is provided with a rack 25, the inside of the clamping block 221 is provided with an inner cavity 26, a motor 27 is installed on one side of the clamping block 221, a gear 28 is installed on one side of the motor 27, the gear 28 is installed in the inner cavity 26, and the gear 28 meshes with the rack 25.

[0039] During testing, the motor 27 is started to drive the gear 28 to rotate, and the gear 28 drives the test plate 23 to move left and right to test the barbell bar.

[0040] The clamping port 29 has a limiting groove 210 at its inner bottom. One side of the limiting block 222 is hinged to the inner wall of the limiting groove 210. The bottom of the limiting groove 210 has an insertion hole 211 that extends to the bottom of the clamping block 221. An adjusting rod 212 is installed inside the insertion hole 211. A spring 213 is sleeved on the adjusting rod 212. A first magnetic block 214 is provided at the bottom of the adjusting rod 212.

[0041] The limiting block 222 has a slope on one side, which faces the inlet of the clamping port 29. When the barbell enters from the inlet, it squeezes the slope, causing the top of the limiting block 222, which protrudes from the limiting groove 210, to fully retract into the limiting groove 210. The telescopic rod moves downward along the insertion hole 211 and compresses the spring 213. When the barbell enters the clamping port 29, it is reset by the bottom spring 213.

[0042] The bottom of the device body 1 is provided with a plug rod 13, and the top of the plug rod 13 is equipped with a second magnetic block 14. When the clamping block 221 moves downward, the plug rod 13 can be inserted into the plug hole 211, and the first magnetic block 214 and the second magnetic block 14 attract each other.

[0043] When the clamping block 221 moves downward, the bottom insertion rod 13 is inserted into the insertion hole 211. When the first magnetic block 214 and the second magnetic block 14 come into contact, they attract each other. At this time, the hydraulic cylinder moves slightly upward and pulls the telescopic rod downward, so that the position of the top of the limiting block 222 protruding from the limiting groove 210 is completely retracted into the limiting groove 210. At this time, the barbell bar can be moved out to the clamping port 29.

[0044] The counterweight section 3 is used to add weight to the barbell bar. When the detection section 2 moves the barbell bar upward, the counterweight section 3 gradually increases the weight on both ends of the barbell bar. The counterweight section 3 includes a counterweight groove 31 opened at the top of the detection port 11. A first telescopic rod 32 is fixed to the inner top of the counterweight groove 31. A second telescopic rod 33 is installed at the bottom of the first telescopic rod 32. A counterweight block 34 is fixed to the bottom of the second telescopic rod 33. The second telescopic rod 33 can move up and down along the first telescopic rod 32. An arc-shaped groove 35 is provided at the bottom of the counterweight block 34. The counterweight block 34 gradually rises in the direction away from the clamping block 221.

[0045] The counterweight 3 is used to add weight to the barbell bar, simulating the stress on the barbell bar during actual use, thereby improving the accuracy of the test. The counterweight groove 31 is used to accommodate and guide the counterweight 3, ensuring its stable operation during the test. The second telescopic rod 33 can move up and down along the first telescopic rod 32. The counterweight block 34 is a component used to provide additional weight, simulating the stress on the barbell bar during actual use. The design of the counterweight block 34 ensures that the weight is evenly distributed during the test, thereby improving the accuracy of the test. The bottom of the counterweight block 34 is provided with an arc-shaped groove 35, which allows the barbell bar to contact the arc-shaped groove 35 and push the counterweight block 34 upward. At the same time, the counterweight block 34 can gradually increase the weight on both ends of the barbell bar when applying weight, ensuring a more uniform and stable weight distribution during the test. This simulates the stress on the barbell bar during actual use, ensuring the accuracy and reliability of the test results.

[0046] Simultaneously, the bending degree of the barbell can be tested while adding counterweight. During the test, the motor 27 is started to drive the gear 28 to rotate, and the gear 28 drives the test plate 23 to move left and right to test the barbell.

[0047] The bottom of the detection port 11 is provided with a second groove 15, and both ends of the detection plate 23 extend into the second groove 15. The inner sidewall of the second groove 15 is provided with an inclined groove 16, through which the barbell bar after detection is discharged.

[0048] When the detection plate 23 moves down to the bottom along the second groove 15, the bottom insertion rod 13 is inserted into the insertion hole 211. When the first magnetic block 214 and the second magnetic block 14 come into contact, they attract each other. At this time, the hydraulic cylinder moves slightly upward and pulls the telescopic rod downward, so that the position of the top of the limiting block 222 protruding from the limiting groove 210 is completely retracted into the limiting groove 210. The barbell rod can be removed from the clamping port 29 and slide down to the outside of the device body 1 through the inclined groove 16, which is convenient for unloading.

[0049] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification.
