Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pump crankshafts, in particular to a detection platform for high-pressure pump crankshafts. Background Technique

[0002] The high-pressure pump crankshaft is the most important component in the high-pressure pump. The crankshaft outputs and drives other accessories on the high-pressure pump to work. The crankshaft is jointly affected by the centrifugal force of the rotating mass, the gas inertia force that changes periodically, and the reciprocating inertia force, so that the crankshaft bears the action of bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface needs to be wear-resistant, work evenly, and have good balance.

[0003] The utility model patent application document with the publication number of "CN220063713U" discloses a crankshaft hardness detection device, which mainly consists of a workbench, a fixing plate, a railing, a support plate, a fixing ring, a connecting rod one, a fixing block one, a fixing block two, and a connecting rod two. Through the rotational connection between the fixing block one and the connecting rod one, the fixing ring is driven to rotate, and then through the action of the lock catch, the spring, and the stabilizing plate, the crankshaft can be fixed more firmly on the support plate, solving the problem that the surface flatness of the crankshaft is uneven and it is difficult to fix.

[0004] The crankshaft hardness detection device disclosed in the above document has the following defects: The crankshaft hardness detection device detects the hardness of the crankshaft by operating the controller to control the indenter. However, during the detection process, only the positions of some outer surfaces of the crankshaft can be detected. When it is necessary to detect another part of the outer surface, the crankshaft needs to be manually taken out from the support plate for position adjustment, and the practicability is poor.

[0005] It can be seen from this that the existing crankshaft detection device does not have a structure that is convenient for adjusting the circumferential side surface of the crankshaft, and it is necessary to improve the existing deficiencies and provide a detection platform for high-pressure pump crankshafts. Content of the Utility Model

[0006] The purpose of the utility model is to provide a detection platform for high-pressure pump crankshafts to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a detection platform for a high-pressure pump crankshaft, which comprises a workbench. One end of the workbench is provided with a rectangular block, and the upper surface of the rectangular block is provided with a first sliding groove.

One end of the unidirectional screw rod penetrates through the rectangular block and extends outward. A placing seat is slidably connected to the outer surface of the unidirectional screw rod. A first driving motor is installed on the upper surface of the placing seat. A coupling is installed at the output end of the first driving motor. A rotating handle is installed at one end of the unidirectional screw rod. A bidirectional screw rod is rotatably connected inside the second sliding groove. One end of the bidirectional screw rod penetrates through the workbench and extends outward. Two sliders are slidably connected to the outer surface of the bidirectional screw rod and are symmetrically arranged. A clamping structure is arranged on the upper surface of the sliders. A second driving motor is installed at one end of the bidirectional screw rod.

The output end of the electric telescopic rod penetrates through the support frame and extends downward. A detection component is installed at the output end of the electric telescopic rod.

[0010] Furthermore, a placing block is arranged on the upper surface of the workbench. A placing groove is opened on the upper surface of the placing block. Connecting blocks are arranged at both ends of the placing block.

[0011] Furthermore, the clamping structure comprises a baffle plate, a clamping plate, a guide rod, an anti-detachment block and a spring. The baffle plate is installed on the upper surface of the slider. A through hole is opened in the middle of the baffle plate. The guide rod is slidably connected inside the through hole. A clamping plate is arranged at one end of the guide rod. An anti-detachment block is arranged at the other end of the guide rod. One end of the spring is installed on the outer surface of the baffle plate, and the other end of the spring is installed on the outer surface of the clamping plate.

[0012] Furthermore, a groove is opened at one end of the clamping plate away from the guide rod. A plurality of rollers are rotatably connected inside the groove.

[0013] Furthermore, the connecting block is installed on the upper surface of the workbench through bolts.

[0014] The utility model has the following beneficial effects:

[0015] (1) By the cooperative use of the first motor and the coupling, the crankshaft can be rotated on the placing block in the utility model, without manual rotation of the crankshaft, which is convenient for the detection component to detect the circumferential sides at different positions, making the data more comprehensive and having better practicability.

[0016] (2) The clamping plate provided in the utility model can achieve a good clamping effect on the crankshaft. At the same time, the spring provided reduces the amplitude of vibration during the rotation of the crankshaft, achieving a good damping effect.

A first driving motor 4 is installed on the upper surface of the placement seat 3. A coupling 5 is installed at the output end of the first driving motor 4. A rotating handle 6 is installed at one end of the one-way screw 2. A two-way screw 7 is rotatably connected inside the second chute 103. One end of the two-way screw 7 penetrates through the workbench 1 and extends outward. The outer surface of the two-way screw 7 is slidably connected with sliders 8. The sliders 8 are fixed into two and are symmetrically arranged. A clamping structure 9 is provided on the upper surface of the sliders 8. A second driving motor 10 is installed at one end of the two-way screw 7.

[0028] A support frame 104 is provided on the upper surface of the workbench 1. An electric telescopic rod 11 is installed on the upper surface of the support frame 104. The output end of the electric telescopic rod 11 penetrates through the support frame 104 and extends downward.

[0029] A placement block 13 is provided on the upper surface of the workbench 1. A placement groove 1301 is provided on the upper surface of the placement block 13. Connection blocks 1302 are provided at both ends of the placement block 13.

[0030] The clamping structure 9 includes a baffle 901, a clamping plate 902, a guide rod 903, an anti-detachment block 904 and a spring 905. The baffle 901 is installed on the upper surface of the slider 8. A through hole is provided in the middle of the baffle 901. A guide rod 903 is slidably connected inside the through hole.
