Description

Technical Field

[0001] The present invention relates to the technical field of debugging tool structures, and in particular to a debugging tool structure with pressure and displacement calibration functions. Background Art

[0002] The currently commonly used pressure and accuracy calibration structure is mainly composed of two tools: pressure calibration tool and displacement calibration tool. Both tools are tested online separately to achieve pressure and displacement calibration.

[0003] The existing structure can only perform pressure and displacement calibration functions separately, and the debugging process cycle cannot be guaranteed. When the production line frequently changes products and the cycle time is required, the usual practice is to have two people on the production line: one person removes the pressure calibration tooling, while the other fixes the prepared displacement calibration tooling on the line for testing. However, the actual effect is not ideal, mainly for the following reasons: on-site operating space varies, and some workshops cannot accommodate two people working simultaneously; the pressure and displacement tooling is generally fixed to the press shaft, and frequent removal for calibration can damage the threads and prevent tightening; external threads are commonly processed by turning and tapping, and thread grinding is generally rarely used. From a manufacturing cost perspective, if the press shaft cannot be used due to thread damage, the manufacturing cost is very high, and the press shaft processing cycle is long. Based on the above analysis, fixing the pressure and displacement calibration tooling to the press shaft is not only inconvenient to remove, but also causes wear and damage to the press shaft threads, resulting in damage and scrap of the part. Summary of the Invention

[0004] The purpose of the present invention is to provide a pressure and displacement calibration structure which can overcome the problems of the existing structure, such as long installation period, damage to the working pressing shaft thread, and resulting in the scrapping of the pressing shaft.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A debugging tooling structure with pressure and displacement calibration functions includes a base plate, above which a press shaft and a reaction shaft are provided, the press shaft and the reaction shaft being arranged on the same axis, an open test sleeve being provided between the press shaft and the reaction shaft, the two ends of the test sleeve being respectively connected to the press shaft and the reaction shaft, and the opening of the test sleeve being used for placing a pressure calibration sensor, a calibration block, and a difference block.

[0007] Preferably, the press shaft and the reaction shaft are respectively fixed above the base plate through support seats.

[0008] Preferably, pads and raising blocks are respectively provided at the corners of the four sides of the bottom plate, and the pads and raising blocks are used to be connected and fixed with the jacking precision pallet.

[0009] Preferably, a handle is provided on the bottom plate, and the handle is convenient for operators to carry.

[0010] Preferably, the pressure calibration sensor is connected to an L-shaped pressure instrument fixing block, and a mushroom-head handle for easy lifting is provided on the top of the pressure instrument fixing block.

[0011] Preferably, the press shaft and the reaction shaft are connected to both ends of the test sleeve through guide bushing rods respectively.

[0012] Preferably, grooves are provided on the press shaft and the guide bushing rod; an anti-fall adjustment bolt is provided between the press shaft and the guide bushing rod and between the reaction shaft and the guide bushing rod, one end of the anti-fall adjustment bolt is arranged in the groove, and the other end of the anti-fall adjustment bolt is passed through the outside of the guide bushing rod.

[0013] Preferably, bushings are provided between the press shaft and the guide bushing rod and between the reaction force shaft and the guide bushing rod.

[0014] The present invention has a simple structure and can quickly take and place the pressure calibration sensor, calibration block, and differential block, thereby saving time for replacing tooling, ensuring the production line rhythm requirements, and avoiding damage to the working pressure shaft thread, which would cause the pressure shaft to be scrapped; the operation can be completed by a single operator, solving the problem of limited on-site operating space.

An open test sleeve 8 is provided between the press shaft 7 and the reaction shaft 6, and the opening of the test sleeve 8 is used to place a pressure calibration sensor 10, a calibration block, and a difference block; the two ends of the test sleeve 8 are respectively connected to the press shaft 7 and the reaction shaft 6 with respective guide bushing rods 5, and the two ends of the press shaft 7 and the reaction shaft 6 are respectively passed through the two ends of the test sleeve 8; bushings 14 are provided between the press shaft 7 and the guide bushing rod 5 and between the reaction shaft 6 and the guide bushing rod 5; one side of the press shaft 7 is a press, and one side of the reaction shaft 6 is a plurality of interlocking cylinders. (The technical content of cylinder interlocking is prior art and is not the invention of this application, so it will not be described in detail here.)

[0023] Grooves are provided on the press shaft 7 and the guide bushing rod 5; anti-fall adjustment bolts 11 are provided between the press shaft 7 and the guide bushing rod 5 and between the reaction shaft 6 and the guide bushing rod 5, one end of the anti-fall adjustment bolt 11 is set in the groove, and the other end of the anti-fall adjustment bolt 11 is passed through the outside of the guide bushing rod 5; when the press shaft 7 and / or the reaction shaft 6 are in motion, the press shaft 7 and / or the reaction shaft 6 can move within the groove range corresponding to the anti-fall adjustment bolt 11, and the anti-fall adjustment bolt 11 is used for limiting.

[0024] The pressure calibration sensor 10 is connected to the L-shaped pressure instrument fixing block 12. A mushroom-head handle 13 is provided on the top of the pressure instrument fixing block 12 for easy lifting. The mushroom-shaped handle 13 is convenient for taking and placing. When replacing the displacement calibration block, the mushroom-shaped handle 13 can be directly lifted. After removing the pressure calibration sensor 10, the calibration block and the difference block are placed. The calibration block and the difference block are also equipped with a mushroom-shaped handle 13.

[0025] Furthermore, pads 2 and raising blocks 3 are respectively provided at the corners of the four sides of the base plate 1, and the pads 2 and raising blocks 3 are used to connect and fix with the jacking precision pallet; the raising blocks 3 are provided with positioning pin holes and are positioned by diamond pins and round pins. The height of the raising blocks 3 can be adjusted according to the actual design of the position of the jacking precision pallet, and can be accurately positioned with the jacking precision pallet; the raising blocks 3 adjust the tooling to be parallel to the press.

[0026] Furthermore, a handle 4 is provided on the bottom plate 1 for manual carrying.

[0027] The press shaft 7 can be made of standard parts, or it can be modified or made according to actual needs and placed in the guide bushing rod 5 on the support seat 9 to ensure that the press shaft 7 does not shake.

[0028] The working state of the present invention is as follows:

[0029] Stress testing:

[0030] S1: The operator holds the handle 4 and connects and positions the present invention through the pin hole of the shim block 3 with the jacking precision tray;

[0031] S2: The operator places the pressure calibration sensor 10 connected to the pressure instrument fixing block 12 into the opening of the test set 8 through the mushroom head handle 13;

[0032] S3: The interlocking cylinder on the reaction force side presses and locks the reaction force pressure shaft 6, and the press on the pressure side pushes the press pressure shaft 7 forward. One end of the press pressure shaft 7 inserted into the test sleeve 8 presses the pressure calibration sensor 10 in the test sleeve 8. After recording the pressure value of the pressure calibration sensor 10, the press retreats, and the operator removes the pressure calibration sensor 10 connected to the pressure instrument fixing block 12 through the mushroom head handle 13.

[0033] Displacement test:

[0034] S1: The operator places the calibration block into the opening of the test set 8 through the mushroom head handle;

[0035] S2: First test: The interlocking cylinder on the reaction side presses and locks the reaction pressure shaft 6, and the press on the pressure side pushes the press pressure shaft 7 forward. One end of the press pressure shaft 7 inserted into the test sleeve 8 presses the calibration block in the test sleeve 8. At this time, the value of the press displacement is recorded, and the press moves backward.

[0036] S3: The operator places the differential block into the opening of the test sleeve 8 using the mushroom-head handle. The differential block is located between the calibration block and the press shaft 7.

[0037] S4: In the second test, the interlocking cylinder on the reaction side presses and locks the reaction pressure shaft 6, and the press on the pressure side pushes the press pressure shaft 7 forward. One end of the press pressure shaft 7 inserted into the test sleeve 8 presses the difference block in the test sleeve 8. At this time, the value of the press displacement stroke is recorded again, and the press moves backward.

[0038] S5: The difference between the press displacement stroke value of the second test and the press displacement stroke value of the first test is compared with the difference block to complete the displacement test.

[0039] The present invention has a simple structure and can quickly take and place the pressure calibration sensor, calibration block, and differential block, thereby saving time for replacing tooling, ensuring the production line rhythm requirements, and avoiding damage to the working pressure shaft thread, which would cause the pressure shaft to be scrapped; the operation can be completed by a single operator, solving the problem of limited on-site operating space.
