Description

Technical Field

[0001] The invention relates to the field of molding and processing of a washing machine tripod, in particular to automatic grinding and processing equipment for molding a washing machine tripod. Background Art

[0002] A washing machine tripod generally refers to a structure used to support a washing machine and ensure that it remains stable during operation. The tripod is usually made of metal material and is a three-dimensional triangular frame structure that bulges upward (such as Fig.11 , Fig.12 As shown in the figure, the back of the tripod support foot is provided with a strip groove for installing a shockproof foot pad or a shockproof strip to reduce the vibration and noise generated during the operation of the washing machine. A central column for fixing the tripod or connecting the tripod with other components is installed in the middle of the front of the tripod. The front of the tripod support foot is provided with evenly arranged holes and grooves for assisting in fixing the tripod. The tripod may produce burrs and sharp edges during the molding process. In order to ensure the safety of the product and avoid scratches during use, the back and sides of the tripod need to be ground to improve the surface smoothness of the tripod, improve the dimensional accuracy and geometric accuracy of the tripod, and ensure that it cooperates well with other parts of the washing machine.

[0003] However, there are currently the following problems in the process of grinding the washing machine tripod:

[0004] 1. Since the washing machine tripod is a three-dimensional triangular frame structure, when it is fixed only by the center column, the overall stability and effectiveness of the tripod are insufficient. When the washing machine tripod is subjected to grinding force, it is easy to move in position, thereby affecting the direction and angle of the grinding force on the tripod, resulting in uneven grinding quality on the tripod surface and reduced grinding efficiency.

[0005] 2. Usually, a single support leg is ground once. This method not only makes the overall grinding efficiency less than ideal, but also makes the tripod's force uneven when the stability of the tripod is already low, thereby affecting the grinding effect of a single support leg and making the grinding degree of multiple support legs uneven.

[0039] See also Figure 2 , Figure 3 and Figure 4 The clamping assembly includes an arc-shaped clamping plate 218 uniformly arranged above the fixed circular plate 211 in the circumferential direction, a control rod is installed on the outer side of the arc-shaped clamping plate 218, and the lower end of the control rod is connected to an L-shaped connecting rod 219 symmetrically distributed about the control rod and hinged to the outer ring surface of the fixed circular plate 211 through a pin shaft 1. The pin shaft 1 is rotatably connected to the control rod and is also slidably connected to the L-shaped connecting rod 219. A connecting plate 220 corresponding to the arc-shaped clamping plate 218 is installed on the inner side of the movable ring 214. The connecting plate 220 is connected to the other end of the corresponding L-shaped connecting rod 219 through a pin shaft 2. The pin shaft 2 is rotatably connected to the connecting plate 220 and is also slidably connected to the L-shaped connecting rod 219. A pushing plate 221 is installed at the lower end of the movable ring 214. The lower end of the pushing plate 221 is connected to the pushing end of the electric push rod 222, and the electric push rod 222 is installed at the lower end of the processing table 1 through a mounting frame.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A mounting groove connected to the corresponding opening groove and opened at the upper end of the processing table 1 is provided on the side of the inclined plate 216 away from the fixed circular plate 211, and a support plate 223 is installed in the mounting groove for sliding up and down. The upper end of the support plate 223 close to the inclined plate 216 is tilted downward, and evenly arranged telescopic springs 224 are connected between the support plate 223 and the bottom wall of the mounting groove.

[0041] During the specific work: first, the tripod to be ground needs to be placed on the upper end of the processing table 1, with its front side facing down and its back side facing up, so that the back and sides of the tripod can be ground later. During this process, the center column in the middle of the front of the tripod is inserted into the positioning sleeve 213. The placement position of the tripod can be pre-positioned by the cooperation between the center column and the positioning sleeve 213. At the same time, the supporting feet of the tripod can be placed at the position corresponding to the abutment plate 223 on the upper end of the processing table 1, and it is ensured that the supporting feet of the tripod are directly opposite to the abutment plate 223. The abutment plate 223 can not only be used to pre-align the placement direction of the tripod, but also to limit the contact of the supporting feet of the tripod.

[0042] Next, the push plate 221 can be pushed upward by the electric push rod 222, and the push plate 221 pushes the moving ring 214 to move upward synchronously. When the moving ring 214 moves upward, the L-shaped connecting rod 219 is driven to rotate upward around the hinge point between the L-shaped connecting rod 219 and the fixed circular plate 211 through the connecting plate 220 and the second pin. The other end of the L-shaped connecting rod 219 drives the control rod and the arc clamping plate 218 to move synchronously toward the direction of the center column through the first pin until the circumferentially arranged arc clamping plates 218 simultaneously clamp the part of the center column that passes through the positioning sleeve 213, and the center column is clamped and fixed by the arc clamping plates 218.

[0043] In addition, when the movable ring 214 moves upward, the inclined plate 216 and the block 225 are driven to move upward synchronously through the side plate 215. The inclined plate 216 can move up and down along the open slot. When the arc-shaped clamping plate 218 clamps the central column, the inclined plate 216 moves up to fit with the front side of the tripod support foot. The blocks 225 on the inclined plate 216 are symmetrically inserted into the inner wall of the hole groove on the front side of the tripod support foot. The cooperation of the inclined plate 216, the block 225 and the tripod support foot can provide a stable supporting force for the tripod, and limit the rotation of the tripod to prevent the tripod from being deflected due to the grinding force during the subsequent grinding process, thereby further improving the stability of the tripod.

The auxiliary plate 338 and the folding frame 115 are connected with telescopic columns 341 which are evenly arranged in the circumference. The end of the folding frame 115 away from the circular bevel gear 116 is equipped with an L-shaped bracket 342 which is evenly arranged in the circumference. A connecting column is connected between the horizontal section of the L-shaped bracket 342 and the support frame 117.

[0048] During operation: after the tripod is fixed, the electric slider 112 can be used to drive the support frame 117 to move downward along the vertical guide rail 111, and the support frame 117 drives the motor 113, the connecting column, the L-shaped bracket 342, the folding frame 115, the middle grinding assembly, and the side grinding assembly to move downward synchronously, and the guide block 344 moves downward synchronously along the guide column 343 with the L-shaped bracket 342. The guide column 343 can be used to support and guide the movement of the L-shaped bracket 342 and the guide block 344.

At the same time, the L-shaped frame 319 drives the rotating rod and the horizontal bevel gear 322 to move synchronously. The rotating rod drives the telescopic section of the elastic telescopic rod 320, the motor 2 325 and the vertical bevel gear 321 to move outward synchronously through the L-shaped frame, and the L-shaped frame 319 drives the square block 323 Moving synchronously along the sliding rod 324, the elastic telescopic rod 320 automatically extends due to the external pulling force, and after the rotating roller 2 located on the inner side drives the horizontal annular grinding belt 312 to fit the side of the tripod support leg, the elastic telescopic rod 320 drives the L-shaped frame, motor 2 325, vertical bevel gear 321, horizontal bevel gear 322, rotating rod and L-shaped frame 319 to automatically reset to maintain the tightness of the horizontal annular grinding belt 312 to fit the side of the tripod support leg.

[0049] In addition, as the side grinding assembly moves downward, the inverted frame 315 drives the square plate 316, the rectangular plate, the vertical rod 317 and the baffle plate 318 to move downward synchronously. The baffle plate 318 is initially in a downward tilted state. When the side grinding assembly reaches the grinding position, the baffle plate 318 just enters the strip groove on the back of the tripod support leg. The baffle plate 318 is used to block the strip groove to prevent the debris generated in the subsequent grinding process from entering the strip groove and being difficult to clean, thereby affecting the overall quality of the tripod after grinding. In the subsequent process of the side grinding assembly moving downward along the support leg of the tripod, the inverted frame 315 can move downward relatively along the baffle plate 318 through the cooperation between the square plate 316, the rectangular plate and the vertical rod 317 The baffle plate 318 is blocked by the abutment plate 223 and does not move. Before the side grinding assembly moves to the lower end of the tripod support leg, the inverted frame 315 first contacts the inclined section of the abutment plate 223 through the square plate 316 and the rectangular plate. The abutment plate 223 is pressed by the abutment pressure to compress the telescopic spring 224 and slide downward along the rectangular groove to prevent the abutment plate 223 from interfering with the movement of the side grinding assembly, thereby ensuring that the back and sides of the support leg of the tripod are fully ground. After the telescopic spring 224 is pressed into the rectangular groove, the inverted frame 315 continues to move and can drive the baffle plate 318 to move synchronously through the square plate 316, the rectangular plate and the vertical plate to gradually disengage from the strip groove, and the baffle plate 318 that gradually disengages from the tripod is pressed on the upper end of the abutment plate 223.

[0050] In the initial state, the automatic telescopic rod 114 and the telescopic column 341 are both in a retracted state, and the connecting shaft 331 drives the grinding disc 332 and the grinding roller 335 to be away from the tripod and not in contact with it, so that the side grinding assembly can perform the grinding operation smoothly.

[0051] See also Figure 1 , Figure 5 , Figure 7 and Figure 8 A driving assembly for driving three sets of side grinding assemblies to move simultaneously along the supporting legs of the tripod is arranged above the processing table 1, and the driving assembly includes a moving block 345 installed on the upper end of the inverted frame 315, and a lead screw 346 threadedly connected to the moving block 345 and tilted downward is rotatably installed between the folding frame 115 and the corresponding guide block 344, and an inclined rod 347 slidably connected to the moving block 345 and installed between the folding frame 115 and the guide block 344 is arranged above the lead screw 346, and the inclined rod 347 is parallel to the lead screw 346, and after the lead screw 346 rotates and passes through the folding frame 115, an inclined bevel gear 348 meshing with the circular bevel gear 116 is installed.

[0052] See also Figure 1-Figure 12During operation: after the side grinding assembly reaches the grinding position, the motor 113 can drive the connecting shaft 331 to rotate through the automatic telescopic rod 114. Since the circular bevel gear 116 is always matched with the spline through the circular sleeve, the up and down movement of the connecting shaft 331 will not affect the smooth rotation of the circular bevel gear 116. At this time, the circular bevel gear 116 can rotate synchronously with the connecting shaft 331, and the grinding disc 332 rotates synchronously therewith but does not contact the tripod. With the rotation of the circular bevel gear 116, the inclined bevel gear 348 meshing with it rotates synchronously, and the inclined bevel gear 348 drives the lead screw 346 to rotate synchronously. When the lead screw 346 rotates, it drives the moving block 345 to move downward synchronously along the inclined rod 347. The moving block 345 drives the side grinding assembly to move downward synchronously along the supporting foot of the tripod, and the vertical annular grinding belt 311 is always The rotating roller 1 located at the bottom is in contact with the back of the tripod's support foot, and the horizontal annular grinding belt 312 is in contact with the side of the tripod through the rotating roller 2 located on the inside. During the downward movement of the side grinding assembly, the vertical annular grinding belt 311 and the horizontal annular grinding belts 312 on both sides cooperate to grind the back and sides of the tripod's support foot until the side grinding assembly completely completes the grinding of the tripod's support foot to remove burrs that may exist on the back and sides of the tripod's support foot. In addition, with the cooperation of the circular bevel gear 116 and the inclined bevel gear 348, the three groups of side grinding assemblies distributed in a triangle can grind the three support feet of the tripod respectively at the same time, which not only increases the grinding efficiency and ensures the uniformity of the grinding quality, but also ensures that the tripod is in a stable and uniform non-stress state, thereby improving the grinding quality of the tripod.

[0053] In addition, when the side grinding assembly moves along the supporting leg to a position away from the top of the tripod, the automatic telescopic rod 114 can push the connecting shaft 331 to move downward, and the grinding disc 332 drives the outer gear ring 333 and the arc-shaped guide frame, auxiliary plate 338, connecting gear 334, grinding roller 335 and connecting shaft 331 to move downward synchronously, and the telescopic column 341 extends synchronously until the lower end surface of the grinding disc 332 fits against the top of the tripod, and the grinding roller 335 moves downward to fit against the arc-shaped side surface of the tripod (the connecting surface between the side surfaces of adjacent supporting legs). Since the side grinding assembly is still in a moving state at this time, the connecting shaft 331 can drive the grinding disc 332 to rotate and grind the top of the tripod. In order to remove the possible unevenness on the top of the tripod, during the rotation of the grinding disc 332, the outer gear ring 333 rotates synchronously therewith, and the rotation of the outer gear ring 333 can drive the connecting gear 334 to rotate, and the connecting gear 334 engages with the grinding roller 335, thereby causing the grinding roller 335 to rotate by itself. The multiple grinding rollers 335 arranged along the arc of the arc-shaped side of the tripod can be used to fully grind the arc-shaped side of the tripod. After the grinding disc 332 and the grinding roller 335 grind the tripod for a certain period of time, the middle grinding assembly and the auxiliary parts can be driven by the automatic telescopic rod 114 to move up and away from the tripod to prevent the middle grinding assembly and the auxiliary parts from excessively grinding the top and arc-shaped side of the tripod.

[0054] After the side grinding assembly completes a top-down moving grinding, the electric slider 112 can be used to drive the side grinding assembly to move up to a position slightly away from the tripod support leg, and then the motor 2 325 can be used to drive the horizontal bevel gear 322 on one side to rotate. The horizontal bevel gear 322 can drive the rotating roller 2 on the outside to rotate through the rotating rod, and the rotating roller 2 on the inside rotates synchronously therewith through the horizontal annular grinding belt 312. The horizontal bevel gear 322 can also drive the vertical bevel gear 321 to rotate at the same time. The vertical bevel gear 321 drives the rotating roller 1 on the top to rotate through the elastic telescopic rod 320, and the rotating roller 1 on the bottom rotates with The vertical annular grinding belt 311 rotates synchronously, and the horizontal annular grinding belt 312 on the other side rotates synchronously with the cooperation of the corresponding vertical bevel gear 321 and the horizontal bevel gear 322, so that the grinding points of the horizontal annular grinding belt 312 and the vertical annular grinding belt 311 after grinding the tripod are rotated to other places, so that the subsequent horizontal annular grinding belt 312 and the vertical annular grinding belt 311 can effectively grind the tripod at new grinding points, avoiding the horizontal annular grinding belt 312 and the vertical annular grinding belt 311 from continuously grinding at a single point, which accelerates the speed of large wear and reduces the service life.

[0055] After completing the switching of the grinding points of the vertical annular grinding belt 311 and the horizontal annular grinding belt 312, the circular bevel gear 116 can be driven by the motor 113 to rotate in the opposite direction, and the inclined bevel gear 348 drives the lead screw 346 to rotate in the opposite direction synchronously. At this time, the side grinding assembly can be reset from bottom to top along the supporting foot of the tripod. During this process, the side grinding assembly does not contact the supporting foot of the tripod. Then, the baffle 318 is manually pushed to restore it to its original tilted state. The pin shaft 3 at the lower end of the vertical rod 317 is located inside the upper end of the corresponding baffle 318. Subsequently, the back and sides of the tripod can be reciprocatedly ground in the same manner as described above, and the grinding points of the horizontal annular grinding belt 312 and the vertical annular grinding belt 311 can be replaced before each grinding to ensure the effectiveness of the grinding until the tripod is completely ground. Then, the middle grinding assembly, the auxiliary parts and the side grinding assembly can be reset in the opposite manner as described above, and then the tripod can be released by the clamping assembly. Finally, the ground tripod can be removed from the processing table 1 to obtain the ground tripod.
