Description
Technical Field
[0001] The utility model relates to the technical field of torsion spring standing tests, in particular to a tooling for the standing test of a governor torsion spring. Background Art
[0002] Standing is a basic requirement for springs. The finished springs must be stood to prevent them from affecting the performance and normal operation of mechanical equipment or components during operation. The standing treatment of a torsion spring is to twist the heat-treated torsion spring to the working limit torsion angle, and twist it briefly once or multiple times to achieve the purpose of stabilizing the geometric dimensions of the spring. During the manufacturing process of the governor spring, it is required that the spring can withstand a certain force when twisted by a certain angle. However, since the governor spring is a torsion spring with a small size, the conventional spring standing device has a complex structure, a high manufacturing cost and is not suitable for the torsion spring products used in the governor, resulting in the difficulty for the operator to conduct the standing test of the governor spring without the assistance of tooling.
[0003] Therefore, how to provide a tooling for the standing test of a governor torsion spring, which can assist the operator to conduct the standing test of the governor torsion spring, and has the characteristics of simple structure, firm clamping and low manufacturing cost, is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model
[0004] In view of this, the utility model provides a tooling for the standing test of a governor torsion spring, aiming to solve the technical problems that the conventional spring standing device cannot be effectively applied to the standing test of the governor torsion spring, and has a complex structure and a high manufacturing cost.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme:
[0006] The utility model provides a tooling for the standing test of a governor torsion spring. The governor torsion spring includes a spiral tube part, a torsion arm one and a torsion arm two; the torsion arm one and the torsion arm two are fixedly arranged at both ends of the spiral tube part in a one-to-one correspondence and are both arranged along the length direction of the spiral tube part; the tooling includes:
[0007] A base,
[0008] A positioning shaft assembly, which is vertically and fixedly installed at the upper end of the base to limit the spiral tube part by passing through the inner hole of the spiral tube part; positioning holes are opened at the upper end of the base corresponding to the periphery of the positioning shaft assembly;
[0009] A torsion arm one limiting assembly, which is located on the periphery of the lower part of the positioning shaft assembly and is slidably arranged on the upper end of the base along the radial direction of the positioning shaft assembly, and can press and fix the torsion arm one on the outer peripheral wall of the positioning shaft assembly;
[0010] A twist handle, which is arranged parallel to the base, is movably sleeved on the upper part of the positioning shaft assembly and can be clamped with the second torsion arm to drive the governor torsion spring to perform elastic twisting when rotating;
[0011] A handle positioning rod, the lower end of which is detachably inserted into the positioning hole, and the upper end of which is detachably inserted into the twist handle to limit the rotation of the twist handle.
[0012] The utility model provides a tool for the standing test of the torsion spring of a speed regulator. When in use, the torsion spring of the speed regulator is sleeved on the positioning shaft assembly and the torsion arm one is directed downward and the torsion arm two is directed upward; the torsion arm one limiting assembly is used to press and fix the torsion arm one; then the torsion handle is sleeved on the upper part of the positioning shaft assembly and axially slides to press against the upper end of the spiral tube part, and the torsion handle is clamped on the torsion arm two, and the torsion handle is held and rotated to drive the torsion arm two to rotate around the positioning shaft assembly, thereby causing the torsion spring of the speed regulator to be elastically twisted by a certain angle; then the torsion handle is positioned by the handle positioning rod to prevent the torsion spring of the speed regulator from rotating, thereby assisting the operator to successfully complete the standing test according to the preset torsion angle and torsion time.
[0013] As a further improvement of the above technical solution, it also includes a limiting nut, which is threadedly connected to the upper end of the positioning shaft assembly to press against the upper end of the twist handle for limiting.
[0014] The beneficial effect of the above technical solution is that the limiting nut plays a role in limiting the twisting handle to prevent it from falling out of the upper end of the positioning shaft assembly, thereby improving the safety and reliability of the experiment.
[0015] As a further improvement of the above technical solution, the positioning shaft assembly includes a positioning mandrel and a reducing shaft sleeve; a mandrel mounting hole is opened in the middle of the base; the lower end of the positioning mandrel is installed in the mandrel mounting hole; the reducing shaft sleeve can be adaptably mounted on the positioning mandrel and corresponds to the bottom of the twist handle; the twist handle is movably mounted on the upper part of the positioning mandrel.
[0016] The beneficial effects of the above technical solution are: for speed regulator torsion springs with different inner diameters, only the positioning core shaft can be used for positioning; or reducing sleeves with different outer diameters can be selected and sleeved on the positioning core shaft to increase the adaptability to speed regulator torsion springs with different inner diameters; because when the speed regulator torsion spring is twisted by a certain angle, its inner diameter will become smaller accordingly, the design and use of reducing sleeves with different outer diameters can improve the assembly adaptability of the inner diameter of the spiral tube portion of the speed regulator torsion spring, thereby improving the stability of the support for the spiral tube portion, improving the coaxiality of the spiral tube portion and the positioning core shaft in the torsion state, and preventing the speed regulator torsion spring from causing uncontrollable axial bending deformation when twisted, thereby affecting the experimental accuracy.

[0018] A chute is radially formed in the upper end of the base along the positioning mandrel. The bottom of the clamping block has a slider, and the slider is adaptively and slidably connected in the chute. A first clamping groove for embedding and clamping the first torsion arm is formed in one side of the clamping block close to the positioning mandrel along the height direction of the positioning mandrel. The first ejector rod is threadedly connected to the clamping block along the length direction of the chute and can be rotatably inserted into the first clamping groove to press and fasten the first torsion arm against the outer peripheral wall of the positioning mandrel or the stepped bushing;
[0019] The stop block is fixed to the upper end of the base and is located on the side of the clamping block away from the positioning mandrel. The second ejector rod is threadedly connected and penetrates through the stop block along the length direction of the chute, and can press and fix the clamping block against the outer peripheral wall of the positioning mandrel or the stepped bushing.
[0020] The beneficial effects of the above technical solution are as follows: The clamping block can slide in the chute to change its position, so as to adapt to torsion springs of different diameters. When installing the governor torsion spring, the first torsion arm is located in the first clamping groove for clamping and limiting, and at the same time, the first ejector rod presses the first torsion arm against the outer peripheral wall of the positioning mandrel or the stepped bushing to further prevent the first torsion arm from bending or tilting and shifting during the standing test, improving the test accuracy; The second ejector rod functions to press the clamping block so that the outer peripheral wall of the positioning mandrel or the stepped bushing seals the notch of the first clamping groove to prevent the first torsion arm from slipping out of the first clamping groove.
[0021] As a further improvement of the above technical solution, the torsion handle includes a handle rod and a collar; the collar is fixed to one end of the handle rod and is movably sleeved on the upper part of the positioning mandrel; a second clamping groove for passing through and clamping the second torsion arm is radially formed in the bottom wall of the collar.
[0022] The beneficial effects of the above technical solution are as follows: When installing the second torsion arm of the governor torsion spring, it is passed through and clamped in the second clamping groove for positioning.
[0023] As a further improvement of the above technical solution, the handle rod is arranged radially along the collar, the second clamping groove is arranged corresponding to the handle rod and communicates with the annular hole of the collar; the second clamping groove extends integrally along the length direction of the handle rod to the handle rod.
[0024] The beneficial effects of the above technical solution are as follows: The second clamping groove communicates with the annular hole of the collar, so that the second torsion arm passing through the second clamping groove can be attached to the outer peripheral wall of the positioning mandrel or the stepped bushing; The second clamping groove extends to the handle rod, forming a strip-shaped clamping groove distributed radially along the positioning mandrel, which can adapt to standing tests of governor torsion springs with different diameter specifications.
[0025] As a further improvement of the above technical solution, a positioning jack is axially formed on the handle rod corresponding to one end of the second clamping groove away from the ring hole of the collar; the upper part of the handle positioning rod is movably inserted into the positioning jack to position the handle rod.
[0026] The beneficial effect of the above technical solution is that the handle positioning rod is inserted and matched with the positioning jack. During use, the handle positioning rod is passed through the positioning jack from top to bottom and its lower end is inserted into the positioning hole, which is convenient for installation and disassembly and easy to operate.
[0027] As a further improvement of the above technical solution, angle scale lines for determining the rotation angle of the torsion handle are provided on the top end face of the positioning mandrel.
[0028] The beneficial effect of the above technical solution is that the angle of the torsion spring of the speed governor driven by the torsion handle can be observed and determined through the angle scale lines.
[0029] As a further improvement of the above technical solution, there are multiple positioning holes; the multiple positioning holes are arranged at intervals around the positioning shaft assembly.
[0030] The beneficial effect of the above technical solution is that different positioning holes correspond to different torsion angles, which is convenient for carrying out standing experiments under different torsion angle conditions.

[0044] As Figures 1 to 4 shown, a tooling for the standing experiment of the governor torsion spring. The governor torsion spring 9 includes a spiral tube portion 91, a first torsion arm 92, and a second torsion arm 93; the first torsion arm 92 and the second torsion arm 93 are fixedly arranged at both ends of the spiral tube portion 91 in a one-to-one correspondence and are both arranged along the length direction of the spiral tube portion 91; it includes:
[0045] A base 1,
[0046] A positioning shaft assembly 2, which is vertically and fixedly installed on the upper end of the base 1 to limit the spiral tube portion 91 by passing through the inner hole of the spiral tube portion 91; a positioning hole 11 is provided on the upper end of the base 1 corresponding to the periphery of the positioning shaft assembly 2.
[0047] A first torsion arm limiting assembly 3, which is located on the periphery of the lower part of the positioning shaft assembly 2 and is slidably arranged on the upper end of the base 1 along the radial direction of the positioning shaft assembly 2, and can press and fix the first torsion arm 92 on the outer peripheral wall of the positioning shaft assembly 2.
[0048] A torsion handle 4, which is arranged parallel to the base 1, is movably sleeved on the upper part of the positioning shaft assembly 2 and can be clamped with the second torsion arm 93 to drive the elastic torsion of the governor torsion spring when rotated.
[0049] A handle positioning rod 5, the lower end of which is detachably inserted into the positioning hole 11, and the upper end of which is detachably inserted into the torsion handle 4 to limit the rotation of the torsion handle 4.
[0050] When the tooling for the standing experiment of the governor torsion spring provided in this embodiment is in use, the governor torsion spring is sleeved on the positioning shaft assembly 2 with the first torsion arm 92 facing downwards and the second torsion arm 93 facing upwards; the first torsion arm limiting assembly 3 is used to press and fix the first torsion arm 92; then the torsion handle 4 is sleeved on the upper part of the positioning shaft assembly 2 and axially slides to press against the upper end of the spiral tube part 91, and the torsion handle 4 is clamped on the second torsion arm 93. By rotating the torsion handle 4 by hand, the second torsion arm 93 is driven to rotate around the positioning shaft assembly 2, so that the governor torsion spring is elastically twisted by a certain angle; then the handle positioning rod 5 is used to position the torsion handle 4 to prevent the governor torsion spring from rotating back, and the operator can be assisted to successfully complete the standing experiment according to the preset torsion angle and torsion time.
[0051] In some embodiments, it further includes a limit nut 6, and the limit nut 6 is threadedly connected to the upper end of the positioning shaft assembly 2 to press against the upper end of the torsion handle 4 for limiting.
[0052] The limit nut 6 plays a role in limiting the torsion handle 4 to prevent it from slipping out of the upper end of the positioning shaft assembly 2, improving the safety and reliability of the experiment.
[0053] Specifically, to prevent a limit nut 6 from rotating together with the torsion handle 4 and affecting the limit accuracy, two limit nuts 6 are provided for locking; the two limit nuts 6 are abutted and locked to play an anti-loosening role.
[0054] In some embodiments, the positioning shaft assembly 2 includes a positioning mandrel 21 and a stepped bushing 22; a mandrel mounting hole 12 is formed in the middle of the base 1; the lower end of the positioning mandrel 21 is installed in the mandrel mounting hole 12; the stepped bushing 22 can be properly sleeved on the positioning mandrel 21 and corresponding to the lower part of the torsion handle 4; the torsion handle 4 is movably sleeved on the upper part of the positioning mandrel 21.
[0055] For governor torsion springs with different inner diameters, only the positioning mandrel 21 can be selected for positioning; or stepped bushings 22 with different outer diameter specifications can be sleeved on the positioning mandrel 21 to increase the adaptability to governor torsion springs with different inner diameters; since the inner diameter of the governor torsion spring will become smaller correspondingly when it is twisted by a certain angle, the design and use of stepped bushings 22 with different outer diameters can improve the assembly adaptability to the inner diameter of the spiral tube part 91 of the governor torsion spring, thereby improving the stability of the support for the spiral tube part 91, improving the coaxiality between the spiral tube part 91 and the positioning mandrel 21 in the torsion state, and preventing uncontrollable axial bending deformation of the governor torsion spring when it is twisted, which affects the experimental accuracy.
[0056] Specifically, the lower end of the positioning mandrel 21 is adaptively inserted into the mandrel mounting hole 12. A threaded hole is provided at the bottom end of the base 1 corresponding to the circumferential side of the positioning mandrel 21, and a set screw 14 is installed in the threaded hole. The set screw 14 can fixedly install the positioning mandrel 21 in the mandrel mounting hole 12 to limit the rotation of the positioning mandrel 21.
[0057] In some embodiments, the torsion arm one limiting assembly 3 includes a clamping block 31, a first ejector rod 32, a stop block 33, and a second ejector rod 34.
[0058] A chute 13 is radially provided at the upper end of the base 1 along the positioning mandrel 21. The bottom of the clamping block 31 has a slider 311, and the slider 311 is adaptively and slidably connected in the chute 13. A first slot 312 for embedding and clamping the torsion arm one 92 is provided on one side of the clamping block 31 close to the positioning mandrel 21 along the height direction of the positioning mandrel 21. The first ejector rod 32 is threadedly connected to the clamping block 31 along the length direction of the chute 13 and can rotatably penetrate into the first slot 312 to press and fasten the torsion arm one 92 against the outer peripheral wall of the positioning mandrel 21 or the stepped bushing 22.
[0059] The stop block 33 is fixed to the upper end of the base 1 and is located on the side of the clamping block 31 away from the positioning mandrel 21. The second ejector rod 34 is threadedly connected and penetrates through the stop block 33 along the length direction of the chute 13, and can press and fix the clamping block 31 against the outer peripheral wall of the positioning mandrel 21 or the stepped bushing 22.
[0060] The clamping block 31 can slide in the chute 13 to change its position, so as to adapt to torsion springs of different diameters. When installing the governor torsion spring, the torsion arm one 92 is placed in the first slot 312 for clamping and limiting. At the same time, the torsion arm one 92 is pressed tightly against the outer peripheral wall of the positioning mandrel 21 or the stepped bushing 22 by the first ejector rod 32 to further prevent the torsion arm one 92 from bending or tilting and shifting during the standing experiment, improving the experimental accuracy. The second ejector rod 34 functions to press the clamping block 31 so that the outer peripheral wall surface of the positioning mandrel 21 or the stepped bushing 22 blocks the notch of the first slot 312 to prevent the torsion arm one 92 from slipping out of the first slot 312.
[0061] Specifically, the stop block 33 is a limiting plate. The stop block 33 is fixedly parallel to the base 1 and corresponds to the upper part of the chute 13 to prevent the clamping block 31 from slipping out of the chute 13. Through holes one and two are respectively provided on both sides of the stop block 33 corresponding to the length direction of the plate surface. Through holes three and four are respectively provided on the base 1 corresponding to the through holes one and two. The through hole one and the through hole three are both cylindrical holes and jointly form a through positioning hole one. The through hole two and the through hole four are both diamond-shaped holes and jointly form a through positioning hole two. A cylindrical pin 7 is inserted into the through positioning hole one, and a diamond pin 8 is inserted into the through positioning hole two to stably position the stop block 33 on the base 1, which is convenient for disassembling and assembling the stop block 33 and can avoid over-positioning of the stop block 33.
[0062] Specifically, both the first ejector rod 32 and the second ejector rod 34 are bolts.
[0063] In some embodiments, the torsion handle 4 includes a handle rod 41 and a collar 42; the collar 42 is integrally connected or welded and fixed to one end of the handle rod 41 and is movably sleeved on the upper part of the positioning mandrel 21; a second slot 421 for passing through and clamping the second torsion arm 93 of the governor torsion spring is radially formed in the bottom wall of the collar 42.
[0064] When the second torsion arm 93 of the governor torsion spring is installed, it is passed through the second slot 421 for clamping and positioning.
[0065] Specifically, when performing the standing experiment, the collar 42 is movably sleeved on the upper part of the positioning mandrel 21, the second torsion arm 93 is embedded in the second slot 421 for clamping, and the bottom end of the collar 42 abuts against the top end of the helical tube portion 91 of the governor torsion spring. During the twisting process of the governor torsion spring, the length of its helical tube portion 91 will become longer. After the governor torsion spring is twisted in place, the limit nut 6 is screwed to slightly press against the top end of the collar 42 for axial limit; the notch of the second slot 421 is always clamped at the bottom position of the second torsion arm 93, which can prevent the second torsion arm 93 from tilting under force during twisting.
[0066] In some embodiments, the handle rod 41 is arranged radially along the collar 42, the second slot 421 is arranged corresponding to the handle rod 41 and communicates with the annular hole of the collar 42; the second slot 421 extends integrally along the length direction of the handle rod 41 to the handle rod 41.
[0067] The second slot 421 communicates with the annular hole of the collar 42. When the governor torsion spring is twisted in place, the inner wall of its helical tube portion 91 is adapted to fit against the outer peripheral wall of the positioning mandrel 21 or the stepped bushing 22, and the second torsion arm 93 passing through the second slot 421 is also adapted to fit against the outer peripheral wall of the positioning mandrel 21 or the stepped bushing 22; the second slot 421 extends to the handle rod 41, forming a strip-shaped slot distributed radially along the positioning mandrel 21, which can be adapted to the standing experiment of governor torsion springs with different diameter specifications.
[0068] Specifically, the bottom wall of the second slot 421 is opened to penetrate to the upper end surfaces of the handle rod 41 and the collar 42 to form a strip-shaped through hole, so as to be adapted to pass through the second torsion arms 93 of different lengths.
[0069] In some embodiments, a positioning jack 411 is axially formed in the handle rod 41 corresponding to one end of the second slot 421 away from the annular hole of the collar 42; the upper part of the handle positioning rod 5 can be movably passed through the positioning jack 411 to position the handle rod 41.
[0070] The handle positioning rod 5 is in plug-in fit with the positioning jack 411. When in use, the handle positioning rod 5 is passed through the positioning jack 411 from top to bottom and its lower end is inserted into the positioning hole 11, which is convenient for installation and disassembly and easy to operate.
[0071] In some embodiments, angle graduation lines 211 for determining the rotation angle of the torsion handle 4 are engraved on the top end face of the positioning mandrel 21.
[0072] The angle by which the torsion handle 4 drives the governor torsion spring to twist can be observed and determined through the angle graduation lines 211.
[0073] In some embodiments, there are multiple positioning holes 11; the multiple positioning holes 11 are arranged at intervals around the positioning shaft assembly 2.
