Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a welding tensile testing device for an upper cover wheel. Background Technology

[0002] The top cover wheel is welded together from two parts. To ensure product quality meets requirements, a tensile test must be performed on the top cover wheel after welding to determine its maximum tensile force. This prevents breakage due to excessive tensile force during use. Existing tensile testing devices are limited in function, testing the product by setting a fixed tensile force value and continuously increasing the force. This method requires multiple tensile tests, resulting in low efficiency and inaccurate values ​​for the ultimate tensile force. Therefore, this invention proposes a welding tensile testing device for the top cover wheel. Utility Model Content

[0003] This utility model achieves the above-mentioned objective through the following technical solution: a welding tensile testing device for a top cover wheel, comprising a machine base, a contour groove provided on the upper end face of the machine base, product locking mechanisms provided on both the upper and lower sides of the contour groove, an avoidance through hole provided in the middle position of the contour groove, a testing mechanism connected to the upper product locking mechanism, a lifting mechanism connected to the testing mechanism and provided on the upper end face of the machine base, and a control panel connected to the testing mechanism and the lifting mechanism provided on the machine base.

[0004] Preferably, the lifting mechanism includes lifting cylinders disposed on both sides of the contour groove, and a support plate is connected to the top rod of the two lifting cylinders.

[0005] Preferably, the testing mechanism includes an upper connecting plate connected to the lower end face of the support plate via a vertical rod, and tension sensors are connected to both sides of the lower end face of the upper connecting plate, with the bottom end of each tension sensor connected to a lower connecting plate.

[0006] Preferably, the locking mechanism includes two locking blocks driven by a gripper cylinder. The ends of the two locking blocks are connected to arc-shaped clamping plates. The gripper cylinder of the upper locking mechanism is fixed to the lower end face of the lower connecting plate. The lower end face of the machine table is connected to a mounting plate via a connecting rod. The gripper cylinder of the lower locking mechanism is connected to the upper end face of the mounting plate.

[0007] Preferably, a plurality of pressure rods are vertically inserted through the lower connecting plate, the bottom end of each pressure rod is connected to a pressure head, and a spring is fitted on the pressure rod. The two ends of the spring are respectively connected to the upper end face of the pressure head and the lower end face of the lower connecting plate.

[0008] The beneficial effects of this utility model are as follows: the locking mechanism locks the upper and lower parts of the upper cover wheel respectively, and the lifting cylinder drives the upper locking mechanism upward to perform a tensile test on the upper cover wheel. The tensile sensor can monitor the tensile force value in real time and transmit the tensile force value to the display screen of the control panel. After the upper cover wheel is damaged, the maximum tensile force value that it can withstand is obtained, which avoids the drawbacks of repeated testing and inaccurate maximum tensile force value in the prior art.

[0014] The present invention will be further described in detail below with reference to specific embodiments.

[0015] Example:

[0016] like Figs. 1 to 3 As shown, the present invention discloses a welding tensile testing device for a top cover wheel, comprising a machine base 1, a contour groove 2 provided on the upper end surface of the machine base 1, product locking mechanisms provided on both the upper and lower sides of the contour groove 2, an avoidance through hole provided in the middle position of the contour groove 2, a testing mechanism connected to the upper product locking mechanism, a lifting mechanism provided on the upper end surface of the machine base 1, and a control panel 3 connected to the testing mechanism and the lifting mechanism on the machine base 1.

[0017] The lifting mechanism includes lifting cylinders 4 located on both sides of the contour groove 2, and support plates 5 are connected to the top rods of the two lifting cylinders 4.

[0018] The testing mechanism includes an upper connecting plate 6 connected to the lower end face of the support plate 5 via a vertical rod. Tension sensors 7 are connected to both sides of the lower end face of the upper connecting plate 6, and a lower connecting plate 8 is connected to the bottom end of the tension sensor 7.

[0019] The locking mechanism includes two locking blocks 10 driven by a gripper cylinder 9. The ends of the two locking blocks 10 are connected to arc-shaped clamping plates 11. The gripper cylinder 9 of the upper locking mechanism is fixed to the lower end face of the lower connecting plate 8. The lower end face of the table surface of the machine base 1 is connected to a mounting plate through a connecting rod. The gripper cylinder 9 of the lower locking mechanism is connected to the upper end face of the mounting plate.

[0020] Multiple pressure rods 12 are vertically inserted through the lower connecting plate 8. The bottom end of each pressure rod 12 is connected to a pressure head 13. A spring 14 is fitted on each pressure rod 12. The two ends of the spring 14 are respectively connected to the upper end face of the pressure head 13 and the lower end face of the lower connecting plate 8.

[0021] The working process of this utility model is as follows: After welding, the upper cover wheel will have a through hole that is larger in the middle and smaller at both ends. This utility model is used to test the maximum tensile force that can destroy the upper cover wheel. The welded upper cover wheel is placed into the contour groove 2, and the locking block 10 of the locking mechanism located below extends into the through hole. The lifting cylinder 4 drives the support plate 5 downward, and the pressure head 13 presses down on the upper end face of the upper cover wheel, thereby ensuring that the upper cover wheel is installed flat in the contour groove 2. The lifting cylinder 4 continues to drive... The support plate 5 is moved downward until the locking block 10 of the locking mechanism located above extends into the through hole and stops. The two gripper cylinders 9 drive the locking block 10 to separate, and the lifting cylinder 4 drives the support plate 5 upward. The arc-shaped clamping plate 11 hooks onto the inner wall of the locking through hole, thereby performing a tensile test on the upper cover wheel. The pressure sensor monitors the tensile force vertically in real time and transmits it to the control panel 3 until the upper wheel cover is damaged. The tensile sensor 7 detects the maximum tensile force value that the upper cover wheel can withstand.

[0022] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
