Description

Technical Field

[0001] The invention relates to a speed reducer case strength detection device, belonging to the technical field of strength detection equipment. Background Art

[0002] The reducer housing is the basic component for installing each transmission shaft. Since each shaft will generate a relatively large reaction force when transmitting torque when the reducer is working and act on the housing, the housing is required to have sufficient rigidity to ensure the relative position accuracy of each transmission shaft.

[0003] In order to ensure that the strength of the reducer housing can meet the standard, it is generally necessary to conduct strength testing on the reducer housing. The general testing method is to apply pressure to the target point by point to perform internal stress strength testing. However, due to the various structural forms of the reducer housing, after a single point test on the reducer housing, it is necessary to reinstall and fix the reducer housing to change the single point test position, and it is impossible to quickly and comprehensively test the reducer housing. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a speed reducer housing strength detection device, which solves the problem of low speed reducer housing strength detection efficiency in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: a reducer housing strength detection device, comprising:

[0006] A support platform, wherein the surface of the support platform is provided with a detection port for the reducer housing to penetrate;

[0007] A lifting installation platform is arranged below the support platform and is used to install the reducer housing and lift the reducer housing to the upper area of ​​the detection port;

[0008] A strength detection component is movably arranged above the detection area, and the strength detection component includes a housing, and an inner cavity of the housing is provided with a detection head that can be extended outwards;

[0009] A support assembly, used for adjusting a detection position of the strength detection assembly;

[0010] Among them, the support assembly includes a plurality of support rods arranged on a support platform, the upper ends of the support rods are rotatably connected to a connecting block, the connecting block is connected to an inner core plate, an outer expansion plate is slidably sleeved on the inner core plate, one end of the outer expansion plate is provided with a driving source for driving it to slide, and the other end is rotatably connected to the containing shell.

[0011] By adopting the above technical solution, the reducer housing can be quickly and comprehensively tested for strength. Through the support assembly, the position of the strength detection assembly in the detection area can be quickly adjusted, and the detection point can be quickly switched, so that there is no need to readjust the fixed position of the reducer housing, and a larger area of ​​fixed-point strength verification can be achieved. During the adjustment process, the outer expansion plate is driven to slide by the driving source, thereby pushing the containment shell that is rotatably connected to the outer expansion plate to move. Since the containment shell is connected to multiple outer expansion plates, and the outer expansion plates are connected to the rotating part through the inner core plate, when the outer expansion plate on one side pushes the containment shell, the other outer expansion plates connected to the containment shell can cooperate to slide and rotate, thereby achieving the position adjustment of the strength measurement assembly.

[0012] The present invention is further configured as follows: an installation groove is provided on the outer wall of the accommodating shell, a rotating screw is provided in the installation groove, the end of the outer expansion plate is sleeved on the rotating screw, an internal gear is provided at the upper end of the rotating screw, and the internal gear is detachably engaged with an external gear ring.

[0013] By adopting the above technical solution, the overall height of the containment shell can be accurately adjusted, so that before the strength test, the outer gear ring is engaged with the inner gear to drive the inner gear to rotate, so that the rotating screw rotates, thereby achieving the height adjustment of the containment shell. The higher the height, the smaller the stroke that the detection head set in the inner cavity of the containment shell can feed after it descends to the detection point where the pressure head abuts against the reducer housing, and the smaller the stress intensity that can be applied. Conversely, the greater the stress intensity that can be applied.

[0014] The present invention is further configured as follows: the lifting mounting platform also includes a driving base, a lifting shaft is arranged on the driving base, a magnetic suction cup is arranged on the upper end of the lifting shaft, a plurality of spacer rods are arranged on the magnetic suction cup, the upper ends of the spacer rods are connected to the through-hole support plate, and spacer springs are sleeved on the spacer rods.

[0015] By adopting the above technical solution, the reducer housing can be quickly fixed. When fixing the reducer housing, first place the reducer housing on the through-hole pallet, drive the lifting shaft to rise, and push the reducer housing into the detection area. When the through-hole pallet rises to the circular opening, it first abuts against the bottom surface of the outer ring support platform of the circular opening. At this time, the lifting shaft continues to rise, thereby compressing the air spring. When the compression of the compression spring reaches the maximum, the magnetic suction cup and the bottom surface of the through-hole pallet overlap with each other, so that the reducer housing is adsorbed on the through-hole pallet by the suction force of the magnetic suction cup. After the inspection is completed, the reducer housing descends with the through-hole pallet. During the descent, the magnetic suction cup and the through-hole pallet are separated from each other, and the suction force of the magnetic suction cup on the reducer housing is also reduced. In this way, the reducer housing can obtain the maximum adsorption force after being transferred to the detection area, and the adsorption force is reduced when leaving the detection area, thereby realizing the rapid fixation and removal of the reducer housing.

[0016] The present invention is further configured as follows: the outer ring of the circular opening is provided with a circular slide groove, a transparent protective plate is slidably clamped on the circular slide groove, a fixed circular ring is provided on the side of the transparent protective plate, and a lap plate extends outward from the side of the fixed circular ring and is connected to the support rod.

[0017] By adopting the above technical solution, the transparent protective plate arranged on the circular slide can enable the measurement personnel to view the measurement situation in real time, and at the same time can protect the measurement personnel to prevent the reducer housing from cracking during the measurement process and injuring the measurement personnel.

[0018] The present invention is further configured as follows: pin holes are evenly distributed on the through-hole support plate, the pin holes are used to clamp a limit piece, the limit piece includes a fixing pin, a hollow shell is provided on the fixing pin, at least three sliding holes are provided on the wall surface of the hollow shell, a limit slide rod is slidably provided in the sliding hole, an oblique block is connected to the limit slide rod, an end cover is connected to the upper end of the hollow shell, an adjusting knob is rotatably connected to the center of the end cover, the adjusting knob is connected to the adjusting screw, the adjusting screw is threadedly connected to a triangular cone, and a slide rod is penetrated through the triangular cone.

[0019] By adopting the above technical solution, the reducer housing placed on the through-hole support plate can be laterally limited by the limiting member in conjunction with the pin hole, thereby preventing the reducer housing from shifting due to insufficient suction during the process of being lifted into the detection area.

[0020] The present invention is further configured as follows: a driving member for driving the detection head to extend and retract is arranged inside the accommodating shell; a pressure head is arranged at one end of the detection head located outside the accommodating shell; and the end of the detection head is rotatably connected to the pressure head.

[0021] By adopting the above technical solution, the detection head is driven to extend and retract through the driving member. During the rotation and descent of the detection head, the pressure head contacts the detection point of the reducer housing and gradually increases the pressure. At this time, the detection head is continued to be driven to rotate and descend. The rotating connection can avoid the pressure head from rotating when the detection head rotates, causing the pressure head to be offset and affecting the detection result.

[0022] The present invention is further configured as follows: the outer gear ring comprises a ring body, the outer ring ring is provided with an auxiliary handle, the inner ring ring is provided with a sunken groove, and the inner ring teeth meshing with the inner gear are provided in the sunken groove.

[0023] By adopting the above technical solution, the outer gear ring can mesh with the inner gear to drive the inner gear to rotate, thereby realizing the height adjustment of the containing shell. When the lateral position of the containing shell is adjusted, the outer gear ring is removed so that each set of internal gears and the rotating screw can rotate independently to prevent interference during adjustment.

[0024] The present invention is further configured as follows: a stepped slot is provided at the bottom of the through-hole support plate, and the inner diameter of the stepped slot is equal to the outer diameter of the magnetic suction cup.

[0025] By adopting the above technical solution, the area with the stepped slot is provided, and the through-hole support plate is thinner, so that after the through-hole support plate is attached to the magnetic suction cup, the magnetic suction cup provides a stronger adsorption force on the reducer housing. At the same time, through the provision of the slot, the connection parts of the entire device are connected more tightly.

[0026] The beneficial effect of the present invention is that through the setting of the support component, the detection point of the strength detection component can be quickly adjusted, so that after the reducer housing is fixed only once, multi-point detection can be achieved, and there is no need to repeatedly adjust the fixed position of the reducer housing.

[0027] By setting up the lifting installation platform, the reducer case can be quickly fixed on the through-hole support plate. At the same time, the magnetic suction cup can produce the maximum adsorption force on the reducer case after the reducer case rises to the detection area. When the reducer case is being tested, the stability of the reducer case is maintained. After the reducer case drops to the bottom, the magnetic suction cup can be separated from the through-hole support plate under the action of the air spring, reducing the adsorption force on the reducer case, thereby facilitating the reduction gear case to be removed from the through-hole support plate.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0036] A speed reducer housing strength detection device, comprising:

[0037] A support platform 1 is provided with a detection port, which is a circular opening and is located at the center of the support platform 1. The upper space of the area enclosed by the detection port is used as the detection area. A strength detection component 4 is movably arranged above the detection area through a support component 5;

[0038] The lifting installation platform 2 is arranged below the middle of the support platform 1, and the lifting installation platform 2 includes a through-hole support plate 206 for installing and fixing the reducer housing 3;

[0039] The strength detection assembly 4 includes a housing 401, and the inner cavity of the housing 401 is provided with a detection head 402 which can be extended downward and abut against the reducer housing 3;

[0040] A support assembly 5, used for adjusting the detection position of the strength detection assembly 4;

[0041] The support assembly 5 includes a plurality of support rods 501 arranged on the support platform 1, the upper end of the support rod 501 is rotatably connected to a connection block 502, the connection block 502 is connected to an inner core plate 503, an outer expansion plate 504 is slidably sleeved on the inner core plate 503, one end of the outer expansion plate 504 is provided with a driving source 505 for driving the sliding thereof, and the other end is rotatably connected to the containing shell 401.

[0042] When performing strength testing on the reducer housing 3, it is only necessary to lift the reducer housing 3 to the testing area through the lifting installation platform 2, control the detection head 402 to descend to abut against the testing point, continuously increase the abutment force of the detection head 402 on the testing point, observe the surface deformation of the reducer housing 3 at the testing point during the testing process, analyze the test data, and complete the single-point test of the housing;

[0043] When it is necessary to detect the remaining points, it is only necessary to control the support component 5 to adjust the position of the strength detection component 4, and drive the outer expansion plate 504 to slide on the inner core plate 503 through the driving source 505, thereby pushing the containing shell 401 that is rotationally connected to the end of the outer expansion plate 504, and the lateral position adjustment of the strength detection component 4 can be completed.

[0044] After the strength detection component 4 is readjusted to a new detection point, the above-mentioned single-point detection steps are repeated to complete the detection of the remaining points of the reducer housing 3, and there is no need to repeatedly change the fixed position of the reducer housing 3, thereby making the detection result more stable and the detection efficiency faster.

[0045] It should be noted that an extension plate 507 extends from the extension plate 504, a threaded through hole is processed in the center of the extension plate 507, the driving source 504 is specifically a standard screw rod, one end of the driving source 505 is threadedly engaged with the threaded hole in the center of the extension plate 507, and the other end is connected to the driving motor 506. By rotating the driving source 505, the extension plate 507 drives the extension plate 504 to slide.

[0046] The entire strength adjustment assembly 4 can be accurately moved to the target detection point by adjusting the feeding mode of the threaded screw.

[0047] like Figure 1 and Figure 2As shown, a pressure sensor is provided on the detection head 402, which can measure the downward pressure strength of the detection head 402 in real time. An axial roller bearing 404 is connected to one end of the detection head 402 located outside the housing 401, and the detection head 402 is rotatably connected to the pressure head 403 through the axial roller bearing 404. A driving electric cylinder (not shown) for driving the detection head 402 to extend and retract is provided inside the housing 401. The detection head 402 is driven downward by the driving electric cylinder to abut against the detection point, and continuously exert downward pressure on the detection point.

[0048] like Figure 2 As shown, a mounting groove 4011 is provided on the outer wall of the housing 401, a rotating screw 4012 is rotatably provided in the mounting groove 4011, a fixed circular plate is fixed at the upper and lower bottom positions of the mounting groove 4011, the rotating screw 4012 is rotatably installed through the fixed circular plate, and the upper end of the rotating screw 4012 penetrates the fixed circular plate. A through hole is provided at the end of the outer expansion plate 504, and a thread that meshes with the rotating screw 4012 is processed on the inner wall of the through hole, one end of the outer expansion plate 504 is threadedly connected to the rotating screw 4012 through the through hole, and the upper end of the rotating screw 4012 is fixedly connected to the internal gear 4013, and the internal gear 4013 is detachably meshed with the external gear ring 405.

[0049] By controlling the rotation of the outer gear ring 405, all the inner gears 4013 are driven to rotate synchronously, thereby realizing the position adjustment of the entire strength detection assembly 4 in the vertical direction. After the outer gear ring 405 is removed, each inner gear 4013 and the rotating screw 4012 meshing therewith rotate separately, which makes it possible for the rotating screw 4012 to move synchronously with the outer expansion plate 504 sleeved thereon when the housing 401 is pushed by the outer expansion plate 504 to adjust the lateral position. Therefore, when the lateral position adjustment of the strength detection assembly 4 is required, the outer gear ring 405 needs to be removed to avoid interference between the inner gear 4013 and the rotating screw 4012.

[0050] like Figure 3 As shown, the outer gear ring 405 includes a ring body 4051 , an outer ring of the ring body 4051 is provided with an auxiliary handle 4052 , an inner ring of the ring body 4051 is provided with a sunken groove 4053 , and an inner ring locking tooth 4054 meshing with the inner gear 4013 is provided in the sunken groove 4053 .

[0051] The entire ring body 4051 can be rotated more conveniently through the auxiliary grip 4052.

[0052] By arranging the inner ring latching teeth 4054 meshing with the inner gear 4013 in the sunken groove 4053, when the outer gear ring 405 and the inner gear 4013 are meshed with each other, the meshing degree between the two is more compact, and the outer gear ring 405 is lifted by the inner gear 4013, so that the outer gear ring 405 will not shake greatly when rotating. At the same time, the outer gear ring 405 and the inner gear 4013 can be meshed quickly and accurately.

[0053] like Figure 6 As shown, the lifting installation platform 2 includes a driving base 201, a lifting shaft 202 is arranged on the driving base 201, and a through-hole support plate 206 is arranged above the lifting shaft 202 through a connecting structure. When installing and lifting the reducer housing 3, the reducer housing 3 is first placed on the through-hole support plate 206, and then the lifting shaft 202 is driven to rise by the driving base 201, so that the installation and lifting operation of the reducer housing 3 can be completed, and the operation is convenient.

[0054] Specifically, the connection structure includes a magnetic suction cup 203 arranged on the top of the lifting shaft 202, a plurality of spacer rods 204 are arranged in an array along the circumferential direction on the magnetic suction cup 203, the spacer rods 204 are slidably connected to the magnetic suction cup 203 along the vertical direction, the top of the spacer rods 204 are fixedly connected to a through-hole support plate 206, and a spacer spring 205 is sleeved on the spacer rod 204 between the bottom plate of the through-hole support plate 206 and the magnetic suction cup 203, wherein the cross-section of the through-hole support plate 206 is stepped and the top is used to be inserted into the detection port, and a stepped slot 207 for the magnetic suction cup 203 to be inserted is provided at the bottom of the through-hole support plate 206, and the top of the spacer rod 204 is fixed on the top wall in the stepped slot 207;

[0055] During the lifting process of the reducer housing 3, as the lifting shaft 202 rises, the through-hole support plate 206 is inserted into the detection port and the outer side abuts against the bottom surface of the support platform 1. At this time, as the lifting shaft 202 continues to rise, the magnetic suction cup 203 will gradually be inserted into 207, and the air spring 205 will gradually shrink and generate elastic force. As the magnetic suction cup 203 is inserted, the magnetic suction cup 203 will absorb the reducer housing 3 through the through-hole support plate 206, thereby completing the fixation of the reducer housing 3;

[0056] It should be noted that when the magnetic suction cup 203 is not inserted into the stepped slot 207, since the magnetic suction cup 203 has magnetic force, it still has an adsorption effect on the reducer housing 3 placed on the through-hole support plate 206. After the magnetic suction cup 203 is inserted into the stepped slot 207, the adsorption effect will be stronger.

[0057] like Figure 6As shown, the bottom surface of the magnetic suction cup 203 is also provided with a receiving shell 208, and the receiving shell 208 is used to store the air spring 205. When the air spring 205 is compressed to the maximum elastic force, the magnetic suction cup 203 is completely inserted into the stepped slot 207, and the magnetic suction cup 203 is completely attached to the bottom surface of the stepped slot 207. The air spring 205 is completely compressed into the receiving shell 208, thereby preventing the air spring 205 from affecting the mutual attachment of the magnetic suction cup 203 and the stepped slot 207 on the bottom surface of the through-hole support plate 206.

[0058] like Figure 4 and Figure 5 As shown, the through-hole support plate 206 is evenly distributed with latch holes 2061, and a fixing pin 801 is detachably connected to the latch hole 2061, and a hollow shell 802 is arranged on the top of the fixing pin 801. During the installation of the reducer housing 3, by inserting the fixing pin 801 into the latch hole 2061, the hollow shell 802 can be made to abut against the reducer housing 3, and the reducer housing 3 is limited in the horizontal direction, thereby effectively preventing the reducer housing 3 from slipping, so that the reducer housing 3 is stably installed.

[0059] Among them, a spacing compensation mechanism is also provided inside the hollow shell 802, and the spacing compensation mechanism includes a plurality of limit slide bars 803 radially slidably connected to the outer wall of the hollow shell 802, one end of the limit slide bar 803 extends into the hollow shell 802 and is fixed with an oblique block 804, and the other end extends out of the hollow shell 802 and is used to abut against the reducer housing 3. In addition, a spring is also provided between the oblique block 804 and the inner wall of the hollow shell 802, and the spring is sleeved on the limit slide bar 803;

[0060] Among them, the spacing compensation mechanism also includes an adjusting screw 807 rotatably connected to the inside of the hollow shell 802, the top of the adjusting screw 807 is rotatably connected to the end cover 805, a triangular cone 808 is threadedly connected to the adjusting screw 807, a sliding rod 809 is arranged at the bottom of the end cover 805, one end of the sliding rod 809 passes through the triangular cone 808 and is connected to the inner bottom wall of the hollow shell 802, and the top of the adjusting screw 807 passes through the end cover 805 and is fixed with an adjusting knob 806.

[0061] By setting the limiting member 8 and the latch hole 2061, the device can quickly perform lateral limiting on the reducer housing 3 placed on the through-hole support plate 206. After the reducer housing 3 is placed on the through-hole support plate 206, the limiting member 8 is inserted into the latch hole 2061 near the outer periphery of the reducer housing 3. At this time, there may be some limiting members 8 that cannot be completely in contact with the outer wall of the reducer housing. At this time, by rotating the adjusting knob 806, the adjusting screw 807 is driven to rotate, so that the triangular truncated cone 808 threadedly connected to the adjusting screw 807 moves along the axial direction of the adjusting screw 807, thereby pushing the oblique block 804, so that the limiting slide bar 803 connected to the oblique block 804 extends outward from the hollow shell 802 and abuts against the wall of the reducer housing 3, thereby realizing the lateral limiting of the reducer housing 3.

[0062] The two end faces of the triangular cone 808 are both flat. Figure 5 As a front view, the aperture of the upper end face of the triangular truncated cone 808 is larger than the aperture of the lower end face. The sliding rod 809 is disposed through the triangular truncated cone 808, passes through the two end faces of the triangular truncated cone 808, and does not intersect with the side face of the triangular truncated cone 808.

[0063] By cooperating with the pin hole 2061, the reducer housing 3 placed on the through-hole support plate 206 can be laterally limited to prevent the reducer housing 3 from being deflected due to insufficient suction during the process of being lifted into the detection area.

[0064] A stepped slot 207 is provided at the bottom of the through hole support plate 206 , and the inner diameter of the stepped slot 207 is equal to the outer diameter of the magnetic suction cup 203 .

[0065] like Figure 6 As shown, in the area where the stepped slot 207 is provided, the through-hole support plate 206 is thinner, so that after the through-hole support plate 206 is attached to the magnetic suction cup 203, the magnetic suction cup 203 provides a stronger adsorption force on the reducer housing 3. At the same time, through the provision of the slot, the connection parts of the entire device are connected more tightly.

[0066] like Figure 4 As shown, the detection area is surrounded by a circular slide groove 6 arranged on the surface of the support platform 1, and two semicircular transparent protective plates 601 that can slide relatively are slidably arranged on the circular slide groove 6. The upper side of the transparent protective plate 601 is slidably engaged with the fixed ring 7, and each transparent protective plate 601 is made of bulletproof glass. By using transparent bulletproof glass, the operator can intuitively observe the strength detection process.

[0067] Working principle: including the fixation of the reducer housing 3 and the position adjustment of the strength detection component.

[0068] like Figure 4 As shown, during the fixing process of the reducer housing 3, the reducer housing 3 is first placed on the through-hole support plate 206, and the lateral degree of freedom of the reducer housing 3 is limited by the latch hole 2061 on the through-hole support plate 206 in cooperation with the limiter 8, and at this time, the magnetic suction cup 203 arranged below the through-hole support plate 206 generates a certain suction force on the reducer housing 3, so that the reducer housing 3 is attached to the through-hole support plate 206. As the lifting shaft 202 slowly rises, the reducer housing 3 is pushed toward the detection area. During this process, when the magnetic suction cup 203 contacts the magnetic support plate, the suction force of the magnetic suction cup 203 on the bottom surface of the reducer housing 3 reaches the maximum, as shown in FIG. Figure 6 As shown, the protrusion on the magnetic suction cup 203 is inserted into the stepped slot 207 at the bottom of the through-hole support plate 206. Among them, the pin holes 2061 densely arranged on the through-hole support plate 206 also make the magnetic suction cup 203 have a greater suction force on the reducer housing 3, making the reducer housing 3 more stable.

[0069] After the reducer housing 3 is successfully lifted to the detection area, the strength detection assembly 4 is adjusted in the horizontal position through the support assembly 5. First, the detection point for strength detection is determined, and then the driving source 505 is controlled to rotate in the extension plate 507, so that the extension plate 507 drives the external expansion plate 504 connected thereto to slide, thereby pushing the rotating screw 4012 that is rotationally connected to the end of the external expansion plate 504. Figure 2 As shown, Figure 2 As a front view, at this time, the internal gear 4013 connected to the upper end of the rotating screw 4012 is not engaged with the outer gear ring 405, and the rotating screw 4012 can move synchronously with the end of the outer expansion plate 504, thereby pushing the entire strength detection assembly 4 to adjust the lateral position. When one of the outer expansion plates 504 pushes the strength detection assembly 4, the other outer expansion plates 504 are synchronously extended and rotated.

[0070] After the lateral position adjustment is completed, the outer gear is meshed with the inner gear 4013, and the outer gear ring 405 is rotated to drive all the inner gears 4013 to rotate synchronously, so that the rotating screw 4012 rotates in the threaded hole at the end of the outer expansion plate 504. At this time, the outer expansion plate 504 is fixed, so that the entire strength detection assembly 4 is adjusted in the vertical direction as the rotating screw 4012 rotates.

[0071] After the horizontal position and the vertical position are adjusted, the detection head 402 is driven to descend, the pressure head 403 abuts against the detection point, and the downward pressure strength of the pressure head 403 is gradually increased to measure the degree of damage to the detection point under different downward pressure strengths, thereby realizing the strength detection of the reducer housing 3. After the determination of a single detection point is completed, the remaining positions of the reducer housing 3 can be continued to be measured by continuing to adjust the detection position of the strength detection component 4, without the need to disassemble the reducer housing 3 again. This improves the detection efficiency of the reducer housing 3, and at the same time, the reducer housing 3 is not disturbed by other external forces during the detection process, and the fixed position is always kept constant, which is also conducive to improving the accuracy of the detection data.
