Description

Technical Field

[0001] This utility model relates to the field of mechanical testing technology, specifically to a fixture limiting mechanism with dual limiting and multiple angle control for a fixture used in the inner panel assembly of the front longitudinal beam of an automobile. Background Technology

[0002] In automotive front longitudinal beam inner panel assembly inspection fixtures, existing fixture limiting mechanisms typically only have two limiting positions: open and closed. This makes it impossible to control the mechanism to open and close at any angle during the inspection process. This design has the following drawbacks:

[0003] 1. Low inspection efficiency: During the part measurement process, the mechanism needs to be opened frequently for dimension marking and hole position deviation observation, and the mechanism needs to be fully opened to the limit point each time;

[0004] 2. Safety hazards exist: When not fully opened to the limit point, due to the long and heavy cantilever of the mechanism, it is easy to fall during operation, which may crush the operator's hand or arm. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a gauge limiting mechanism with dual limiting and multiple angle control, so as to solve the technical problems of low detection efficiency and safety hazards of existing gauge limiting mechanisms.

[0006] The technical solution to the above-mentioned technical problems is: a gauge limiting mechanism with dual limiting and controllable multiple angles, including a detection component, characterized in that it further includes a fixed base, a limiting base plate, a limiting pin assembly, a limiting block, a hydraulic cylinder, and a connecting block; the limiting base plate is mounted on the fixed base; the limiting pin assembly and the limiting block are respectively fixedly mounted on the limiting base plate; the limiting block is provided with a limiting groove for limiting the connecting block; one end of the connecting block is rotatably connected to the limiting block through a pin 7, and the other end of the connecting block is fixedly connected to the detection component; the hydraulic cylinder is connected between the limiting base plate and the connecting block to control the rotation angle of the connecting block; the limiting pin assembly is used to lock the connecting block when it is in a vertical position.

[0007] A further technical solution of this utility model is that the fixed base includes a base connecting base and a base connecting column, the base connecting column is fixed on the base connecting base, and the limiting base plate is installed on the base connecting column.

[0008] A further technical solution of this utility model is that the connecting block is also provided with a guide groove and a fixing hole; the limiting pin assembly includes a pull ring, a spring, a pin seat, a stop pin, and a limiting pin fixing block. The bottom of the limiting pin fixing block is fixedly installed on the limiting base plate, and the upper part of the limiting pin fixing block is connected to one end of the pin seat by a thread. The pin seat is provided with a stop pin mounting step hole. The small end of the stop pin passes through the stop pin mounting step hole and is connected to the pull ring by a thread. The spring is fitted on the small end of the stop pin. One end of the spring abuts against the bottom of the large end hole of the stop pin mounting step hole, and the other end of the spring abuts against the large end face of the stop pin. When the connecting block is in a vertical position, the large end of the stop pin extends out of the stop pin mounting step hole under the action of the spring and enters the fixing hole through the guide groove to achieve locking.

[0009] A further technical solution of this utility model is that a tightening knob is also installed on the connecting block to fix the relative position of the connecting block and the limiting base plate.

[0010] A further technical solution of this utility model is that a handle is also installed on the connecting block, and the handle is fixed on the connecting block for manually operating the rotation of the connecting block.

[0011] A further technical solution of this utility model is that the hydraulic cylinder is installed between the limiting base plate and the connecting block through a hydraulic cylinder connecting fixing pin.

[0012] Due to the above structure, the gauge limiting mechanism of this utility model with dual limiting and controllable multiple angles has the following advantages compared with the prior art:

[0013] 1. High detection efficiency

[0014] This utility model includes a fixed base, a limiting base plate, a limiting pin assembly, a limiting block, a hydraulic cylinder, and a connecting block; wherein the hydraulic cylinder is connected between the limiting base plate and the connecting block and is used to control the rotation angle of the connecting block. Through the hydraulic cylinder, the detection component can be opened and closed controllably at any angle, which greatly improves the detection efficiency.

[0015] 2. Can achieve dual limit switching

[0016] The hydraulic cylinder of this invention controls the rotation angle of the connecting block, while the limiting pin assembly locks the connecting block when it is in a vertical position. This dual limiting mechanism of the hydraulic cylinder and the limiting pin assembly significantly improves operational safety, preventing the risk of the cantilever of the detection mechanism falling and injuring personnel during operation.

[0036] A gauge limiting mechanism with dual limiting and controllable multiple angles includes a fixed base 1, a limiting base plate 2, a limiting pin assembly 3, a limiting block 4, a hydraulic cylinder 5, a connecting block 6, and a detection assembly 10; wherein,

[0037] The fixed base 1 includes a base connecting base 11 and a base connecting support column 12. The base connecting support column 12 is fixed on the base connecting base 11, and the limiting base plate 2 is installed on the base connecting support column 12. The limiting pin assembly 3 and the limiting block 4 are respectively fixedly installed on the limiting base plate 2. The limiting block 4 is provided with a limiting groove 401 for limiting the connecting block 6. One end of the connecting block 6 is rotatably connected to the limiting block 4 through a pin 7 passing through the limiting block 4, and the other end of the connecting block 6 is fixedly connected to the detection assembly 10. The connecting block 6 is also provided with a guide groove 601 and a fixing hole 602. The hydraulic cylinder 5 is connected between the limiting base plate 2 and the connecting block 6 through a hydraulic cylinder connecting fixing pin 51 and is used to control the rotation angle of the connecting block 6. The hydraulic cylinder 5 is a small hydraulic cylinder with an output force of 1~2 kN. The limiting pin assembly 3 is used to lock the connecting block 6 when it is in a vertical position.

[0038] The limiting pin assembly 3 includes a pull ring 31, a spring 32, a pin seat 33, a stop pin 34, and a limiting pin fixing block 35. The bottom of the limiting pin fixing block 35 is fixedly installed on the limiting base plate 2. The upper part of the limiting pin fixing block 35 is threadedly connected to one end of the pin seat 33. The pin seat 33 is provided with a stop pin mounting step hole 331. The small end of the stop pin 34 passes through the stop pin mounting step hole 331 and is threadedly connected to the pull ring 31. The spring 32 is fitted on the small end of the stop pin 34. One end of the spring 32 abuts against the bottom of the large end hole of the stop pin mounting step hole 331, and the other end of the spring 32 abuts against the large end face of the stop pin 34. When the connecting block 6 is in the vertical position, the large end of the stop pin 34 extends out of the stop pin mounting step hole 331 under the action of the spring 32 and enters the fixing hole 602 through the guide groove 601 to achieve locking.

[0039] A tightening knob 8 is also installed on the connecting block 6 to fix the relative position of the connecting block 6 and the limiting base plate 2. A handle 9 is also installed on the connecting block 6 and fixed to the connecting block 6 for manually operating the rotation of the connecting block 6.

[0040] The detection component 10 is existing technology, and its structure will not be described in detail here.

[0041] The working principle of this utility model is as follows:

[0042] (1) When it is necessary to inspect the parts, pull the stop pin 34 backward by pulling the pull ring 31 so that the stop pin 34 is disengaged from the fixing hole 602 in the connecting block 6;

[0043] (2) Place the detection component 10 into the limiting groove 401 of the limiting block 4 using the handle 9, and tighten the tightening knob 8 to start the part measurement;

[0044] (3) If it is necessary to mark the dimensions or observe the deviation of the hole during the measurement process, loosen the tightening knob 8 and open the detection component 10 at a small angle under the control of the hydraulic cylinder 5;

[0045] (4) After the test is completed, loosen the tightening knob 8 and pull up the test component 10 through the handle 9. The stop pin 34 enters the fixing hole 602 through the guide groove 601 under the action of the spring 32 to lock the connecting block 6 and the test component 10.
