Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a fast feeding device for spring end surface grinding. Background Art

[0002] The spring end grinder is used to perform precise grinding and processing on the upper and lower ends of the spring. It is internally divided into an upper grinding wheel and a lower grinding wheel. A rotatable grinding disc is installed between the upper and lower grinding wheels. The grinding disc is provided with a hole for installing the spring. When the grinding disc rotates, the upper and lower grinding wheels grind the upper and lower end surfaces of the spring on the grinding disc. Currently, when loading the grinding disc, the springs are placed in the spring holes of the grinding disc one by one, which is inefficient.

[0003] In the prior art, for example, the patent with publication number CN205111481U discloses a spring end face grinding device, which includes a frame, a workbench located on the frame, and a rotating shaft passing through the workbench. The rotating shaft is provided with at least one synchronously rotating turntable, and the turntable is evenly provided with spring placement holes. A grinding mechanism fixed to the frame is provided on one side of the turntable, and a hinged vibrating plate is provided above the other side of the turntable. Feed holes corresponding to the placement holes are provided on the vibrating plate, and a feed pipe installed at the lower end of the vibrating plate is provided below the feed holes.

[0004] The above structure can feed the springs sequentially, but due to the light weight of the micro springs themselves and some unavoidable weak magnetism, the springs cannot quickly enter the material holes of the grinding disc when falling, resulting in low feeding accuracy and speed. Utility Model Content

[0005] In view of this, the purpose of the present invention is to propose a fast feeding device for spring end face grinding to solve the problem of low feeding accuracy and rate due to the light weight of the micro spring and some unavoidable weak magnetism, which makes the spring unable to quickly enter the material hole of the grinding disc when falling.

[0006] Based on the above purpose, the utility model provides a fast feeding device for spring end surface grinding, comprising a processing table and a grinding disc rotatably mounted on the processing table, wherein a material hole for accommodating the spring is provided on the top of the grinding disc, and a tooth groove is provided around the outside of the grinding disc;

[0007] A feeding device is clamped inside the tooth groove, and a positioning piece is provided on one side of the feeding device. The positioning piece is used to correspond the feeding device to the tooth groove. A driving structure is movably installed inside the positioning piece, and a base is movably installed at the bottom of the driving structure. The base is fixedly mounted on the processing table, and the driving structure is used to swing the feeding device with the base as the center of the circle;

[0008] The feeding device includes a feed head, a feed channel is opened through the top of the feed head, and a slice corresponding to the feed channel is slidably installed on the bottom of the feed head. The top of the feed head is also fixedly connected to an air inlet pipe, and the end of the air inlet pipe is connected to a stepped groove, which is opened inside the feed head. The inside of the feed head is also provided with an inclined hole connected to the stepped groove and the feed channel.

[0009] Preferably, the driving structure includes a bracket fixedly mounted on one side of the base, a cylinder fixedly mounted on the bracket, an output end of the cylinder is connected to a base plate, one end of the base plate is rotatably mounted on the base, an arm plate is slidably mounted on the top of the base plate, and a spring is connected between the arm plate and the base plate.

[0010] Preferably, the positioning member includes a welt block fixedly mounted on the other end of the base plate, a clamping block fixedly mounted on the top of the welt block, a guide rail block slidably mounted on the bottom of the welt block, the clamping block slidably mounted on the top of the guide rail block, and a clamping column mounted on one side of the clamping block;

[0011] A push rod that contacts the slice is slidably installed inside the clamping block;

[0012] A guide rod is fixedly installed on one side of the top of the welt block close to the clamping block, and a connecting block is sleeved on the outside of the guide rod. One side of the connecting block is fixedly installed with the feed head.

[0013] Preferably, a second spring is provided between the slice and the guide rod, and between the welt block and the guide rail block. One side of the welt block is provided with an arc surface, and a notch is provided inside the welt block to accommodate the sliding of the clamping block.

[0014] Preferably, an oblique groove corresponding to the clamping block is provided at the bottom of the connecting block, and the bottom of the connecting block is in conflict with the top of the clamping block.

[0015] Preferably, a delivery hose connected to the feed channel is fixedly connected to the top of the feed head, the delivery hose is a stepped hole, and there are at least two groups of feed channels and slices.

[0016] The beneficial effects of the present invention are as follows: while the external drive drives the grinding disc to rotate slowly, the driving structure drives the feeding device to swing with the base as the center of the circle. When the feed head corresponds to the material hole, the positioning piece contacts the tooth groove, and the feed head drops accordingly. The multiple groups of feed channels in the feed head are close to the top of the grinding disc. The air source of the air intake pipe is used in conjunction with the air source. In the feed channel, the spring itself is too light and some weak magnetism is unavoidable. The air source passes through the stepped groove and the inclined hole to quickly discharge the material and enter the material hole of the grinding disc, thereby solving the smaller spring drop problem and improving the feeding accuracy and rate.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a fast feeding device for spring end surface grinding includes a processing table 1 and a grinding disc 2 rotatably mounted on the processing table 1. A material hole 3 for accommodating the spring is provided on the top of the grinding disc 2, and a tooth groove 4 is provided around the outside of the grinding disc 2.

[0026] The feeding device 7 is clamped inside the tooth groove 4, and a positioning member 10 is provided on one side of the feeding device 7. The positioning member 10 is used to correspond the feeding device 7 to the tooth groove 4. The driving structure 6 is movably installed inside the positioning member 10, and the base 5 is movably installed at the bottom of the driving structure 6. The base 5 is fixedly installed on the processing table 1, and the driving structure 6 is used to swing the feeding device 7 with the base 5 as the center of the circle;

[0027] The feeding device 7 includes a feed head 8, a feed channel 9 is opened through the top of the feed head 8, and a slice 11 corresponding to the feed channel 9 is slidably installed on the bottom of the feed head 8. The top of the feed head 8 is also fixedly connected to an air inlet pipe 12, and the end of the air inlet pipe 12 is connected to a stepped groove 14. The stepped groove 14 is opened inside the feed head 8, and the inside of the feed head 8 is also provided with an inclined hole 13 connected to the stepped groove 14 and the feed channel 9.

[0028] In this embodiment, an external drive is used to drive the grinding disc 2 to rotate slowly, and at the same time, the driving structure 6 drives the feeding device 7 to swing with the base 5 as the center. When the feed head 8 corresponds to the material hole 3, the positioning member 10 contacts the tooth groove 4, and the feed head 8 drops accordingly. The feed channel 9 in the feed head 8 is close to the top of the grinding disc 2, and the air source of the air inlet pipe 12 is used. In the feed channel 9, the spring itself is too light and some weak magnetism is unavoidable. The air source passes through the stepped groove 14 and the inclined hole 13, and quickly discharges the material into the material hole 3 of the grinding disc 2, solving the smaller spring drop problem.

[0029] As an implementation method, Figure 2 and Figure 3 As shown, the driving structure 6 includes a bracket 61 fixedly mounted on one side of the base 5, a cylinder 62 fixedly mounted on the bracket 61, an output end of the cylinder 62 is connected to a base plate 64, one end of the base plate 64 is rotatably mounted on the base 5, an arm plate 63 is slidably mounted on the top of the base plate 64, and a spring 65 is connected between the arm plate 63 and the base plate 64.

[0030] In this embodiment, the cylinder 62 pushes the bottom plate 64 to move. Since one end of the bottom plate 64 rotates with the base 5, the bottom plate 64 swings around the base 5. The spring 1 65 facilitates the rapid reset of the arm plate 63 on the bottom plate 64, thereby driving the positioning member 10 to intermittently engage with the tooth groove 4 in the grinding disc 2.

[0031] As an implementation method, Figure 3 、 Figure 4 and Figure 5 As shown, the positioning member 10 includes a welt block 15 fixedly mounted on the other end of the base plate 64, a clamping block 17 fixedly mounted on the top of the welt block 15, a guide rail block 16 slidably mounted on the bottom of the welt block 15, the clamping block 17 slidably mounted on the top of the guide rail block 16, and a clamping column 18 mounted on one side of the clamping block 17;

[0032] A push rod 21 is slidably mounted inside the clamping block 17 and contacts the slice 11;

[0033] A guide rod 20 is fixedly mounted on one side of the top of the welt block 15 close to the clamping block 17 , and a connecting block 19 is sleeved on the outside of the guide rod 20 , and one side of the connecting block 19 is fixedly mounted to the feed head 8 .

[0034] In this embodiment, when the arm plate 63 drives the clamping block 17 to engage with the tooth groove 4 in the grinding disc 2, the clamping block 17 and the clamping column 18 move toward the side of the grinding disc 2 and contact the tooth groove 4, the clamping block 17 coincides with the inclined groove of the connecting block 19, and the connecting block 19 and the feed head 8 descend accordingly. The feed channel 9 in the feed head 8 is close to the top of the grinding disc 2, and the push rod 21 pushes the slice 11 to open the opening in the feed channel 9, so that the feed head 8 and the material hole 3 correspond to each other, thereby improving the spring unloading accuracy.

[0035] As an implementation method, Figure 1 、 Figure 2 and Figure 3 As shown, springs 22 are provided between the slice 11 and the guide rod 20, and between the welt block 15 and the guide rail block 16. One side of the welt block 15 is provided with an arc surface, and a notch is provided inside the welt block 15 to accommodate the sliding of the clamping block 17.

[0036] Among them, the bottom of the connecting block 19 is provided with an inclined groove corresponding to the clamping block 17, and the bottom of the connecting block 19 conflicts with the top of the clamping block 17. The inclined groove makes the feed head 8 on one side of the connecting block 19 rise and fall, and the feed head 8 corresponds to the grinding wheel 2.

[0037] In this embodiment, the push rod 21 pushes the slice 11 to open the opening in the feed channel 9, and the spring 22 pulls the slice 11 to return to block the feed channel 9, and can send the spring in the feed channel 9 to the material hole 3 in the grinding disc 2 in an orderly manner.

[0038] As an implementation method, Figure 1 、 Figure 2 and Figure 3 As shown, a delivery hose 23 communicating with the feed channel 9 is fixedly connected to the top of the feed head 8. The delivery hose 23 is a stepped hole. There are at least two groups of feed channels 9 and slices 11.

[0039] In this embodiment, the micro spring utilizes the stepped hole of the conveying hose 23, and the two sets of feed channels 9 increase the feeding speed. At the same time, they cooperate with the air source of the air inlet pipe 12. When entering the feed channel 9, the spring itself is too light and has some weak magnetism that cannot be avoided. The air source is combined with the stepped groove 14 and the inclined hole 13 to quickly feed the material.

[0040] Working principle: When in use, the spring vibrating plate is connected to the conveying hose 23, and the spring to be ground is conveyed to the inside of the feed channel 9 in the feed head 8. At this time, the slicer 11 blocks the feed channel 9, and the air inlet pipe 12 is connected to the external air source, first keeping the grinding disc 2 and the positioning piece 10 in a clamping state;

[0041] First, use an external drive to drive the grinding disc 2 to rotate slowly. When the grinding disc 2 rotates, the arm plate 63 is pulled to slide on the bottom plate 64. At the same time, the cylinder 62 pushes the bottom plate 64 to move. Since one end of the bottom plate 64 rotates with the base 5, the bottom plate 64 swings with the base 5 as the center. When the arm plate 63 drives the clamping block 17 to separate from the tooth groove 4 in the grinding disc 2, the clamping block 17 and the edge block 15 move on the side of the guide block 16 away from the grinding disc 2. The side of the clamping block 17 moves away from the chute and drives the connecting block 19 upward, so that the feed head 8 moves upward, and the grinding disc 2 rotates normally.

[0042] When rotating into the lower material hole 3, the arm plate 63 drives the clamping block 17 to engage with the tooth groove 4 in the grinding disc 2, and the clamping block 17 and the clamping column 18 move toward the side of the grinding disc 2 and contact the tooth groove 4. The clamping block 17 coincides with the inclined groove of the connecting block 19, and the connecting block 19 and the feed head 8 drop accordingly. The feed channel 9 in the feed head 8 is close to the top of the grinding disc 2, and the push rod 21 pushes the slice 11 to open the opening in the feed channel 9, and at the same time cooperates with the air source of the air inlet pipe 12. In the feed channel 9, because the spring itself is too light and some weak magnetism cannot be avoided, the air source is used to pass through the stepped groove 14 and the inclined hole 13 to quickly unload the material and enter the material hole 3 of the grinding disc 2, solving the smaller spring drop problem.
