Description
Technical Field
[0001] The utility model relates to the technical field of oil filter testing equipment, in particular to a tool used for testing the concentricity and verticality of an oil filter. Background Art
[0002] The oil filter, also known as the oil grid, is mainly used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil, thereby protecting the engine. The oil filter generally includes a housing, a filter element, a sealing ring, a bypass valve (safety valve) and a check valve. The finished product inspection items of the oil filter include concentricity and verticality tests. Concentricity will affect the assembly position. The verticality test is an important technical indicator for evaluating cylindrical oil filters. The verticality error directly affects the assembly and use of the oil filter. The verticality test refers to testing the verticality of the threaded cover bottom plate of the oil filter and the axis.
[0003] At present, different testing tools are required for the above two tests. That is, after testing the concentricity, the product needs to be removed from the test equipment and then installed on the detection device for testing the verticality. The testing steps are cumbersome and time-consuming. In addition, in order to fix the oil filter, a connector is usually inserted into the oil outlet of the oil filter, and then the connector is threadedly connected to the test head on the test equipment. Since the test head on the ordinary testing equipment is integrally formed with the rotating shaft of the testing equipment, and the test head needs to drive the oil filter to rotate, during use, the test head will be easily deformed or slipped due to long-term friction and extrusion, thereby affecting the accuracy of the test. Therefore, the test personnel need to reprocess and polish the test head regularly. Since the test head is made of metal, reprocessing and polishing is difficult, time-consuming and labor-intensive.
[0004] In the prior art, a dial indicator can detect concentricity and verticality at the same time. How to design a tool that can cooperate with a dial indicator to simultaneously detect the concentricity and verticality of an oil filter without the need for processing and polishing the test head has become a technical problem that urgently needs to be solved in this field. Summary of the invention

[0034] Reference Figure 1-7 The tooling for testing the concentricity and verticality of an oil filter comprises a support frame 1, on which an assembly head 2 for mounting an oil filter 7 is arranged; a rotating shaft 3 penetrating the assembly head 2 is movably arranged in the assembly head 2, and a through hole 21 for the rotating shaft 3 to pass through is arranged inside the assembly head 2. The rotating shaft 3 can rotate relative to the assembly head 2. One end of the rotating shaft 3 is connected to a handle assembly 4, and the other end is provided with a detachable oil filter connector 5.
[0035] Specifically, the oil filter connector 5 includes a connector 51 connected to the oil outlet shaft of the oil filter 7, and the connector 51 is detachably connected to the oil outlet of the oil filter 7. A plurality of anti-skid grooves 511 are provided on the circumferential side of the connector 51, so that the oil filter 7 can rotate synchronously with the connector 51. A detachable recovery tap 52 is provided at the other end of the connector 51. The connector 51 and the recovery tap 52 are threadedly connected. The rotating shaft 3 has a tap connection portion 31 detachably connected to the recovery tap 52 extending radially outward at one end connected to the oil filter connector 5. The outer diameter of the tap connection portion 31 is larger than the diameter of the internal through hole 21 of the assembly head 2, so that the tap connection portion 31 can be set on the side of the assembly head 2 without being inserted into the through hole 21 of the assembly head 2. The recovery tap 52 is detachably set on the tap connection portion 31 through the fixing rod 6. The tap connection portion 31 is provided with a tap hole 32 for inserting a recycling tap 52, and the tap hole 32 is vertically connected to a fixing hole 33 for passing a fixing rod 6. The fixing rod 6 and the fixing hole 33 are threadedly connected. The fixing rod 6 described in this embodiment is a hexagon socket bolt. The recycling tap 52 of this embodiment is a tap that is recycled after the enterprise has reached the end of its tapping life. The tap is a tool for processing internal threads, one end of which is provided with external threads. The utility model uses the recycling tap 52 as a test head. When the recycling tap 52 is deformed or slips, it is sufficient to replace it with a new recycling tap 52, without spending extra time to re-grind the test head. This design realizes waste utilization. When the recovery tap 52 needs to be replaced, unscrew the fixing rod 6, pull out the damaged recovery tap 52, and then screw the new recovery tap 52 into the connecting head 51, insert the other end of the recovery tap 52 into the tap hole 32 of the tap connecting part 31, and then pass the fixing rod 6 through the fixing installation hole 33 of the tap connecting part 31, and tighten the fixing rod 6 with a hexagonal key until the bottom of the fixing rod 6 abuts against the recovery tap 52, so that the recovery tap 52 can rotate synchronously with the rotating shaft 3.
[0036] The handle assembly 4 includes a turntable 41 mounted on the rotating shaft 3, and the outer end surface of the turntable 41 is provided with a handle 42 for conveniently rotating the turntable 41. Rotating the handle 42 can drive the turntable 41 to rotate, and the turntable 41 drives the rotating shaft 3 to rotate, thereby driving the oil filter connector 5 to rotate.
[0037] The support frame 1 includes a support plate 11, a support column 12 and a base plate 13 which are arranged in sequence from top to bottom, and the assembly head 2 is fixedly mounted on the support plate 11. A plurality of feet 14 are arranged at the bottom of the base plate 13. In this embodiment, four feet 14 are arranged, which are respectively arranged at the four corners of the bottom of the base plate 13.

The number of the first fixing holes 132 described in this embodiment is two. The upper and lower ends of the support column 12 are respectively provided with a second fixing hole 121 and a third fixing hole 122, and the size and number of the third fixing hole 122 are adapted to the first fixing hole 132. The number of the second through holes 21 in this embodiment is two, and the support plate 11 is provided with a fourth fixing hole 111 adapted to the second fixing hole 121, and the side of the fourth fixing hole 111 is provided with a fifth fixing hole 112 for fixing the assembly head 2. The assembly head 2 is provided with a sixth fixing hole 22 for mounting the assembly head 2 on the support plate 11, and the sixth fixing hole 22 corresponds to the fifth fixing hole 112 one by one. The assembly head 2, the support plate 11, the support column 12 and the bottom plate 13 are fixed and mounted by screws or bolts.
[0038] Instructions for use: During the test, first screw the threaded end of the recovery tap 52 into the connector 51 that is compatible with the oil filter 7, then insert the other end of the recovery tap 52 into the tap hole 32 of the tap connection part 31, pass the fixing rod 6 through the fixed mounting hole 33 of the tap connection part 31, and tighten the fixing rod 6 with a hexagonal key until the bottom of the fixing rod 6 abuts against the recovery tap 52, so that the recovery tap 52 can rotate synchronously with the rotating shaft 3. Then align the oil outlet of the oil filter 7 with the connector 51, and rotate the handle 42 to drive the oil filter connector 5 to rotate, thereby screwing the connector 51 into the oil outlet of the oil filter 7. After installation, rotate the handle 42 to drive the oil filter 7 to rotate. During the rotation of the oil filter 7, when the test pointer of the dial indicator 8 is in vertical contact with the circumferential side of the oil filter 7 (such as Figure 8 When the test pointer of the dial gauge 8 is in vertical contact with the bottom plate of the threaded cover of the oil filter 7, the verticality can be tested. During the test, the concentricity and verticality of the oil filter 7 are determined by confirming whether the dial gauge is below 0.5 mm. The principle of using a dial gauge to test concentricity and verticality is a prior art and will not be elaborated here. This test is simple and quick to operate, greatly improving the efficiency of the test.
