Description

Technical Field

[0001] The invention belongs to the technical field of compression resistance detection of reducer housings, and in particular relates to a compression resistance detection device for high-precision reducer housing production. Background Art

[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. Cast iron housing is one of the common materials for reducer housings. Common cast iron materials include gray cast iron, ductile iron, etc. The material determines the strength and durability of the reducer housing.

[0003] The test device for testing the pressure resistance of the vacuum pump housing with the existing publication number CN117606913B includes a first pressure piece, which can form a first arc pressure surface and a first flat pressure surface that match the shape of the outer surface of the vacuum pump housing to be tested; a second pressure piece, which can form a second arc pressure surface and a second flat pressure surface that match the shape of the outer surface of the vacuum pump housing to be tested; and a driving piece, which is used to drive the first pressure piece and the second pressure piece to move closer to and away from each other and to obtain the pressure applied to the first pressure piece and the second pressure piece. The above scheme applies pressure to the vacuum pump housing to be tested through the first arc pressure surface and the second arc pressure surface, and the first arc pressure surface and the second arc pressure surface have more contact areas with the outer wall of the vacuum pump housing to be tested, so that the pressure on the outer wall of the vacuum pump housing to be tested is uniform when the pressure resistance test is carried out, and the accuracy of the measurement structure is increased.

[0004] However, the first arc pressure surface and the second arc pressure surface of the test device for testing the pressure resistance of the vacuum pump casing have more contact area with the outer wall of the vacuum pump casing to be tested.

[0043] like Figure 2 As shown, a high-precision reducer housing production pressure resistance detection device provided by the present invention is provided, wherein the pressure assembly 4 includes a guide sleeve 41, a slide rod 42 and a pressure head 43;

[0044] The bottom surface of the connecting seat 11 is connected with a plurality of guide sleeves 41 , each of which is slidably connected with a slide rod 42 , and one end of each of the slide rods 42 is fixedly connected with a pressure head 43 .

[0045] In this embodiment, the No. 3 electric rod 10 is started to extend, and the No. 3 electric rod 10 drives the connecting seat 11 to descend in height. When the connecting seat 11 drives all the pressure heads 43 to contact the surface of the reducer housing, the sliding rod 42 connected to each pressure head 43 can freely slide vertically in the guide sleeve 41, so all the pressure heads 43 can fit with the surface of the reducer housing; then the inner cavity of the connecting seat 11 is closed, and the No. 3 electric rod 10 is continued to extend. The No. 3 electric rod 10 drives all the pressure heads 43 to squeeze the surface of the reducer housing at the same time. Under the action of the fluidity of the hydraulic oil, when the collapse degree of the reducer housing surface is different, all the pressure heads 43 still maintain the same extrusion force to squeeze the reducer housing surface, thereby improving the accuracy of the compression resistance detection of each position of the reducer housing.

[0046] like Figure 2 As shown, a high-precision pressure resistance detection device for the production of reducer housing provided by the present invention is provided, wherein the pump force component 5 includes a filter box 51, an oil pipe 52, an oil pump 53 and a solenoid valve 54;

[0047] The connection seat 11 is fixedly connected with a filter box 51 . Two oil pipes 52 are connected between the filter box 51 and the connection seat 11 . An oil pump 53 is provided between one of the oil pipes 52 and the filter box 51 . Solenoid valves 54 are provided on both oil pipes 52 .

[0048] In this embodiment, hydraulic oil is stored in the filter box 51, and the oil pump 53 is started, so that the oil pump 53 can drive the hydraulic oil to circulate in the filter box 51 and the connecting seat 11;

[0049] The No. 3 electric rod 10 is started to extend, and the No. 3 electric rod 10 drives the connecting seat 11 to descend in height, and the connecting seat 11 drives all the pressure heads 43 to fit with the surface of the reducer housing, and the two oil pumps 53 are closed through the solenoid valve 54, so as to close the inner cavity of the connecting seat 11, and the No. 3 electric rod 10 continues to extend, and the No. 3 electric rod 10 drives all the pressure heads 43 to squeeze the surface of the reducer housing at the same time.

[0050] like Figure 5 As shown, a high-precision compression resistance detection device for the production of reducer housing provided by the present invention is provided, wherein the thrust assembly 6 includes a piston cylinder 61, a connecting rod 62 and a magnetic block 63;

[0051] The piston cylinder 61 is fixedly connected to the fixing frame 14 , a connecting rod 62 is slidably and sealedly connected in the piston cylinder 61 , one end of the connecting rod 62 is fixedly connected to a magnetic block 63 , and the magnetic block 63 faces the pressure head 43 .

[0052] In this embodiment, the fourth electric rod 12 is started, and the fourth electric rod 12 drives all the magnetic blocks 63 to approach the top surface of the reducer housing. Under the action of the magnetic attraction force, all the magnetic blocks 63 fit the inner wall of the reducer housing, and the magnetic blocks 63 drive the connecting rod 62 to slide in the piston cylinder 61, and the movement of the fourth electric rod 12 is stopped at this time.

[0053] like Figure 3 As shown, a high-precision compression resistance detection device for the production of reducer housing provided by the present invention, the collapse depth display assembly 7 includes a No. 1 display tube 71, a hose 72, a No. 1 liquid outlet pipe 73 and a No. 1 stop valve 74;

[0054] A plurality of No. 1 display tubes 71 are vertically fixedly connected to the end surface of the detection platform 1, and the outer wall of each No. 1 display tube 71 is provided with scale lines. A hose 72 is connected between each No. 1 display tube 71 and a piston cylinder 61, and the hose 72 passes through the end surface of the detection platform 1, and the hose 72 and the detection platform 1 are sealed. All No. 1 display tubes 71 are connected to a No. 1 liquid outlet pipe 73, and the No. 1 liquid outlet pipe 73 is connected to a No. 1 stop valve 74.

[0055] In this embodiment, when the pressure head 43 squeezes the reducer housing and causes the reducer housing to collapse, the inner wall of the reducer housing squeezes the magnetic block 63 at the corresponding position, and the magnetic block 63 drives the connecting rod 62 to move downward in the piston cylinder 61. The connecting rod 62 squeezes the water column in the piston cylinder 61, and the water column in the piston cylinder 61 flows into the No. 1 display tube 71 through the hose 72. The vertical depth of the depression of the inner wall of the reducer housing can be judged by the rising volume of the water column in the No. 1 display tube 71; the No. 1 liquid outlet pipe 73 is connected through the No. 1 stop valve 74, and the height of the water column in the No. 1 display tube 71 can be adjusted to a predetermined position before detection by discharging the water flow in the No. 1 display tube 71.

[0056] like Figure 3 As shown, a high-precision compression resistance detection device for the production of reducer housing provided by the present invention, the collapse amount display assembly 8 includes a second display tube 81, a second liquid outlet pipe 82 and a second stop valve 83;

[0057] The No. 2 display tube 81 is U-shaped and is vertically fixedly connected to the detection platform 1. Both ends of the No. 2 display tube 81 are connected, and both ends of the No. 2 display tube 81 are provided with scale lines. The middle part of the No. 2 display tube 81 is connected to the No. 2 liquid outlet pipe 82, and the No. 2 liquid outlet pipe 82 is provided with a No. 2 stop valve 83.

[0058] In this embodiment, when the reducer housing collapses under the downward pressure of all the pressure heads 43, the air pressure in the reducer housing increases. Under the action of the air pressure, the water column in the second display tube 81 rises. The collapsed volume of the entire reducer housing is determined by adding the volume of the water column corresponding to the rising height of the water column in the collapse display component 8 and the volume corresponding to the rising height of the water column in all the collapse depth display components 7.

[0059] like Figure 6 As shown, a high-precision compression resistance detection device for reducer housing production provided by the present invention is provided. The positioning mechanism 9 includes a No. 2 electric rod 91, a fixed rod 92 and a positioning seat 93. Two No. 2 electric rods 91 are fixedly provided on the end surface of the detection platform 1. The telescopic ends of the two No. 2 electric rods 91 are fixedly connected with the fixed rod 92. One end of the fixed rod 92 is fixedly connected with the positioning seat 93. The positioning seat 93 is arranged parallel to the fixing frame 14. The positioning seat 93 is provided with an inclined surface for abutting against the base of the reducer housing. Sealing pads 15 are provided on the detection platform 1 on both sides of the positioning seat 93.

[0060] In this embodiment, the two No. 2 electric rods 91 are started simultaneously, and the two No. 2 electric rods 91 synchronously drive the positioning seat 93 to move downward, and the inclined surface of the positioning seat 93 abuts against the base of the reducer housing, and the base of the reducer housing is fixed by the two positioning seats 93.

[0061] like Figure 7 As shown, a high-precision pressure resistance detection device for the production of reducer housings provided by the present invention is provided. An airbag 94 is arranged in the positioning seat 93, and a port for the airbag 94 to extend is arranged on the lower side of the inclined surface of the positioning seat 93. The positioning seat 93 is fixedly connected with an air pump 95, and the air pump 95 is connected to the airbag 94.

[0062] When all the pressure heads 43 press down the reducer housing base, the corresponding position of the reducer housing under the row of pressure heads 43 will collapse, so that the reducer housing on both sides of the row of pressure heads 43 will be tilted, resulting in a poor seal between the reducer housing base and the end face of the test bench 1;

[0063] In this embodiment, the air pump 95 is started, and the air pump 95 increases the air pressure in the airbag 94, so that the airbag 94 seals the detection platform 1 and the reducer housing base. When a gap is generated between the reducer housing base and the end face of the detection platform 1, the air pump 95 can fill the gap between the reducer housing base and the end face of the detection platform 1 to ensure the sealing between the reducer housing base and the end face of the detection platform 1, thereby improving the detection accuracy.

[0064] Working principle:

[0065] Place the reducer housing on the end surface of the test bench 1, and start the two No. 2 electric rods 91 at the same time. The two No. 2 electric rods 91 synchronously drive the positioning seat 93 to move downward, and the inclined surface of the positioning seat 93 abuts against the base of the reducer housing. The base of the reducer housing is fixed by the two positioning seats 93;

[0066] Start the extension of the No. 1 electric rod 3, and the No. 1 electric rod 3 drives the pressure assembly 4 to move horizontally to a predetermined position on the upper side of the reducer housing. At this time, the No. 5 electric rod 13 drives the fixing frame 14 to move synchronously, and the fixing frame 14 drives all the magnetic blocks 63 to move to the corresponding lower side of the pressure assembly 4. Then start the No. 4 electric rod 12, and the No. 4 electric rod 12 drives all the magnetic blocks 63 to approach the inner top surface of the reducer housing. Under the action of the magnetic attraction, all the magnetic blocks 63 fit the inner wall of the reducer housing, and the magnetic blocks 63 drive the connecting rod 62 to slide upward in the piston cylinder 61. At this time, the movement of the No. 4 electric rod 12 is stopped;

[0067] The No. 1 liquid outlet pipe 73 is opened through the No. 1 stop valve 74 to adjust the water columns in all No. 1 display tubes 71 to be flush with the same predetermined height. At the same time, the No. 2 liquid outlet pipe 82 is opened through the No. 2 stop valve 83 to adjust the water column in the No. 2 display tube 81 to a predetermined height.

[0068] When the No. 3 electric rod 10 is started to extend, the No. 3 electric rod 10 drives the connecting seat 11 to descend in height. When the connecting seat 11 drives all the pressure heads 43 to contact the surface of the reducer housing, the sliding rod 42 connected to each pressure head 43 can freely slide vertically in the guide sleeve 41, so that all the pressure heads 43 can fit the surface of the reducer housing; the two oil pumps 53 are closed through the solenoid valve 54, thereby closing the inner cavity of the connecting seat 11, and the No. 3 electric rod 10 continues to extend. The No. 3 electric rod 10 drives all the pressure heads 43 to squeeze the surface of the reducer housing at the same time and continuously increase the pressure. Under the action of the fluidity of the hydraulic oil, when the degree of collapse of the reducer housing surface is different, all the pressure heads 43 still maintain the same extrusion force to squeeze the reducer housing surface, thereby improving the accuracy of the compression resistance detection of each position of the reducer housing.

[0069] The collapse depth of the reducer shell at the lower pressure point of each pressure component 4 is recorded by observing the rising height of the water column in all collapse depth display components 7, and the rising height of the water column in the collapse amount display component 8 is observed at the same time. The collapse volume of the entire reducer shell is determined by adding the volume of the water column corresponding to the rising height of the water column in the collapse amount display component 8 and the volume corresponding to the rising height of the water column in all collapse depth display components 7.
