Description

Technical Field

[0001] The present invention belongs to the technical field of motor processing equipment, and particularly relates to a lifting and feeding device. Background Art

[0002] The main functions of the motor housing are to fix the motor stator and dissipate heat from the stator. Therefore, the motor housing mainly consists of a combined structure of two parts: an inner steel sleeve and an outer heat dissipation sleeve. The inner steel sleeve is mainly used for installing the motor stator, and the outer heat dissipation sleeve is mainly used for fixing the steel sleeve and conducting the stator heat transferred on the steel sleeve out. There are two groups of symmetrically arranged heat dissipation structures on the outside of the heat dissipation sleeve. The heat dissipation sleeve and the steel sleeve are connected together by a tight fit method, thereby forming a firm and inseparable housing structure.

[0003] In the processing equipment of the motor housing, it is often necessary to vertically transport the motor housing. However, few existing processing equipment comes with a transportation mechanism, so this operation is basically completed manually, resulting in low transportation efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned technical deficiencies and provide a lifting and feeding device.

[0005] To this end, the present invention provides a lifting and feeding device, including a vertical plate. A fixed plate is fixedly connected to the side of the vertical plate. An elevating plate is arranged above the fixed plate. A first guiding tooth column and an upper top cylinder are arranged on the fixed plate. There are two first guiding tooth columns, which are arranged oppositely. The end of the output shaft of the upper top cylinder is fixedly connected with a bracket. Two groups of first limiting mechanisms are arranged on the bracket. The first limiting mechanism cooperates with the first guiding tooth column to transfer the output stroke of the upper top cylinder to the first guiding tooth column, so that the first guiding tooth column can jack up the elevating plate to rise.

[0006] Further, a plurality of first column teeth are arranged in an array on the first guiding tooth column. The bottom surface of the first column tooth is horizontal, and the top surface is inclined downward. A limiting groove is formed between the plurality of first column teeth.

[0007] Further, the first limiting mechanism includes a positioning plate fixedly connected to the bracket. The positioning plate is a right-angle plate. A movable plate is slidably fitted inside the right-angle plate. The movable plate consists of a clamping part and a guiding part. The guiding part passes through a through hole opened on the vertical surface of the right-angle plate. A semi-circular groove is arranged at the end of the clamping part, so that the clamping part can fit on both sides of the first column tooth. A buckle is arranged in the semi-circular groove, and the buckle straddles the limiting groove, so that the first guiding tooth column cannot move downward relative to the first limiting mechanism.

[0008] Further, a transverse movement cylinder is fixedly connected to the top surface of the right-angle plate. A push plate is fixedly connected to the output shaft of the transverse movement cylinder. A notch is formed at the bottom of the push plate and is engaged with the guiding portion. A push rod with a length greater than the width of the guiding portion is arranged on the guiding portion outside the right-angle plate. The push plate is engaged between the push rod and the positioning plate, so that when the output shaft of the transverse movement cylinder extends, the push plate can drive the push rod to move away from the positioning plate.

[0009] Further, the lifting plate is provided with two second guiding tooth columns, which are arranged oppositely. The bottoms of the two second guiding tooth columns are both fixedly connected to the fixed plate. A plurality of second column teeth are arranged in an array on each second guiding tooth column. The tooth pitch of the second column teeth is the same as that of the first column teeth. The top surface of the second column teeth is horizontal and slopes downward. A limiting groove is formed between the plurality of second column teeth.

[0010] Further, a second limiting mechanism is engaged with the second guiding tooth column. The second limiting mechanism is fixedly connected to the lifting plate. The structure of the second limiting mechanism is the same as that of the first limiting mechanism, and the second guiding tooth column cannot move upward relative to the second limiting mechanism.

[0011] Further, a limiting rod is also arranged between the fixed plate and the lifting plate. The length of the limiting rod is used to determine the lowest point position of the lifting plate. When the lifting plate is at the lowest point and the upper lifting cylinder is at the minimum stroke, the buckle of the first limiting mechanism is just located at the highest point of the limiting groove formed by the first column teeth, and the buckle of the second limiting mechanism is just located at the lowest point of the limiting groove formed by the second column teeth.

[0012] Further, below the engaging portion of the first limiting mechanism, the end of the bracket is in a semi-circular groove, which can provide an upward supporting force for the engaging portion when the first limiting mechanism drives the first guiding tooth column to move upward.

[0013] Further, the horizontal end of the right-angle plate of the positioning plate of the second limiting mechanism coincides with the end of the engaging portion. The horizontal end of the right-angle plate of the positioning plate is in a semi-circular groove, which can provide a downward supporting force for the engaging portion when the second limiting mechanism fixes the lifting plate from descending.

[0014] The present invention provides a lifting and feeding device, which has the following beneficial effects:

[0015] By setting the cooperation of two groups of guiding tooth columns and limiting mechanisms, the rising height of the lifting plate can be not limited by the stroke of the upper lifting cylinder, and the lifting height of the lifting plate can be further extended. By setting the specific length of the limiting rod, when the lifting plate is at the lowest point and the upper lifting cylinder is at the minimum stroke, the buckle of the first limiting mechanism is just located at the highest point of the limiting groove formed by the first column teeth, and the buckle of the second limiting mechanism is just located at the lowest point of the limiting groove formed by the second column teeth; it can make the device return to the initial state faster when the lifting plate descends to the lowest point.

Detailed Embodiments

[0024] The present invention will be further described below in conjunction with the drawings and specific embodiments to facilitate understanding of the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0025] As Figure 1 shown, the present invention provides a lifting and feeding device, including a vertical plate 1, and an installation structure can be provided on the vertical plate 1 to fix the feeding device on other equipment. The side of the vertical plate 1 is horizontally fixedly connected with a fixing plate 2, and a lifting plate 3 is arranged above the fixing plate 2.

[0026] As Figure 2As shown in the figure, a top cylinder 24 is fixedly connected to the bottom surface of the fixed plate 2, and the output shaft of the top cylinder 24 passes through the through hole opened in the center of the fixed plate 2. The top end of the output shaft of the top cylinder 24 is fixedly connected with a bracket 4, and the bracket 4 extends to the left and right sides of the fixed plate 2. Two groups of first limiting mechanisms 7 are symmetrically arranged at the left and right ends of the bracket 4, and two first guiding tooth columns 5 are cooperatively arranged on the two groups of first limiting mechanisms 7. The two first guiding tooth columns 5 are arranged oppositely and pass through the fixed plate 2. The top end of the first guiding tooth column 5 is fixedly connected with the lifting plate 3 to transmit the jacking power to the lifting plate 3. As Figure 3 shown, a plurality of first column teeth 22 are arranged in an array on the first guiding tooth column 5. The bottom surface of the first column teeth 22 is horizontal, and the top surface is inclined downward. Limiting grooves are formed between the plurality of first column teeth 22.

[0027] As Figure 4 shown, the first limiting mechanism 7 includes a positioning plate 9, and the positioning plate 9 is fixedly connected to the bracket 4. The positioning plate 9 is a right-angled plate, and a movable plate 10 is slidably fitted inside the right-angled plate. The movable plate 10 is composed of a clamping portion 11 and a guiding portion 12, and the guiding portion 12 passes through the through hole opened on the vertical surface of the right-angled plate; a semi-circular groove is arranged at the end of the clamping portion 11 so that the clamping portion 11 can be attached to both sides of the first column tooth 22. A buckle 16 is arranged in the semi-circular groove, and the buckle 16 straddles the limiting groove so that the first guiding tooth column 5 cannot move downward relative to the first limiting mechanism 7. A transverse movement cylinder 14 is fixedly connected to the top surface of the right-angled plate, a push plate 15 is fixedly connected to the output shaft of the transverse movement cylinder 14, and a notch is opened at the bottom of the push plate 15 and is clamped on the guiding portion 12. A push rod 17 with a length greater than the width of the guiding portion 12 is arranged on the guiding portion 12 outside the right-angled plate, and the push plate 15 is clamped between the push rod 17 and the positioning plate 9 so that when the output shaft of the transverse movement cylinder 14 extends, the push plate 15 can drive the push rod 17 to move away from the positioning plate 9. A spring 13 is also arranged between the clamping portion 11 and the positioning plate 9 to provide an elastic force for the movable plate 10 to move toward the first guiding tooth column 5.

[0028] As Figure 5 shown, two second guiding tooth columns 6 passing through the lifting plate 3 are arranged on the front and rear sides of the lifting plate 3, and the bottoms of the two second guiding tooth columns 6 are fixedly connected to the fixed plate 2. A plurality of second column teeth 23 are arranged in an array on each second guiding tooth column 6, and the tooth pitch of the second column teeth 23 is the same as that of the first column teeth 22. The top surface of the second column teeth 23 is horizontal and the top surface is inclined downward. Limiting grooves are formed between the plurality of second column teeth 23. A second limiting mechanism 8 is cooperatively arranged on the second guiding tooth column 6, and the second limiting mechanism 8 is fixedly connected to the lifting plate 3. Compared with the structure of the first limiting mechanism 7, the structure of the second limiting mechanism 8 is the same except for the positioning plate 9, and the second guiding tooth column 6 cannot move upward relative to the second limiting mechanism 8.

[0029] In the initial state, the lifting plate 3 is located at the lowest point, and the buckle 16 of the first limiting mechanism 7 is located inside the highest point of the limiting groove formed by the first column teeth 22. Since the bottom surface of the first column teeth 22 is horizontal, the buckle 16 cannot move upward relative to the first guide tooth column 5, and the first limiting mechanism 7 limits the first guide tooth column 5. The buckle 16 of the second limiting mechanism 8 is located inside the lowest point of the limiting groove formed by the second column teeth 23. Since the top surface of the second column teeth 23 is horizontal, the buckle 16 cannot move downward relative to the second guide tooth column 6, and the second limiting mechanism 8 limits the second guide tooth column 6.

[0030] When it is necessary to transport the motor housing 20, the motor housing 20 is stacked together and placed on the lifting plate 3. The output shaft of the transverse cylinder 14 of the second limiting mechanism 8 is extended, so that the push plate 15 drives the movable plate 10 to move away from the second guide tooth column 6. The buckle 16 is separated from the limiting groove formed by the second column tooth 23, and the second limiting mechanism 8 releases the limit on the second guide tooth column 6; then the output shaft of the lifting cylinder 24 is extended to lift the bracket 4. Because the first limiting mechanism 7 does not release the limit on the first guide tooth column 5, the first guide tooth column 5 rises with the bracket 4, and the length of the first guide tooth column 5 between the fixed plate 2 and the lifting plate 3 gradually increases, and the length of the second guide tooth column 6 above the lifting plate 3 gradually decreases. Figure 6 As shown, in this state, when the upper cylinder 24 reaches the longest stroke, the lifting plate 3 reaches the highest point.

[0031] If it is necessary to further raise the height of the lifting plate 3, the output shaft of the transverse movement cylinder 14 of the second limit mechanism 8 shortens, and the movable plate 10 resets under the elastic force of the spring 13. The buckle 16 is located inside the highest position of the limit groove formed by the second column teeth 23. The second limit mechanism 8 re-limits the second guide tooth column 6, preventing the lifting plate 3 from falling, and the relative position between the lifting plate 3 and the second guide tooth column 6 no longer changes. Then, the output shaft of the transverse movement cylinder 14 of the first limit mechanism 7 elongates, causing the push plate 15 to drive the movable plate 10 to move away from the first guide tooth column 5. The buckle 16 separates from the limit groove formed by the first column teeth 22, and the first limit mechanism 7 releases the limit on the first guide tooth column 5. The output shaft of the upward pushing cylinder 24 shortens, driving the bracket 4 to move downward until the upward pushing cylinder 24 reaches the minimum stroke. The output shaft of the transverse movement cylinder 14 of the first limit mechanism 7 shortens, and the movable plate 10 resets under the elastic force of the spring 13. The buckle 16 is located in a certain limit groove formed by the first column teeth 22, and the first limit mechanism 7 re-limits the first guide tooth column 5. The output shaft of the transverse movement cylinder 14 of the second limit mechanism 8 elongates, causing the push plate 15 to drive the movable plate 10 to move away from the second guide tooth column 6. The buckle 16 separates from the limit groove formed by the second column teeth 23, and the second limit mechanism 8 releases the limit on the second guide tooth column 6. Finally, the output shaft of the upward pushing cylinder 24 elongates to lift the bracket 4. Since the first limit mechanism 7 has not released the limit on the first guide tooth column 5, the first guide tooth column 5 rises with the bracket 4, and the length of the first guide tooth column 5 between the fixed plate 2 and the lifting plate 3 gradually increases, while the length of the second guide tooth column 6 above the lifting plate 3 gradually decreases. Repeating the above process enables the lifting height of the lifting plate 3 to be unrestricted by the stroke of the upward pushing cylinder 24, further extending the lifting height of the lifting plate 3. As Figure 7 shown, when the lifting plate 3 rises to the highest point, the buckle 16 of the second limit mechanism 8 is located at the highest point of the limit groove formed by the second column teeth 23; at the same time, the buckle 16 of the first limit mechanism 7 is located at the lowest point of the limit groove formed by the first column teeth 22.

[0032] When the lifting plate 3 needs to reset, the output shaft of the transverse movement cylinder 14 of the first limit mechanism 7 elongates, causing the push plate 15 to drive the movable plate 10 to move away from the first guide tooth column 5. The buckle 16 separates from the limit groove formed by the first column teeth 22, and the first limit mechanism 7 releases the limit on the first guide tooth column 5. The output shaft of the transverse movement cylinder 14 of the second limit mechanism 8 elongates, causing the push plate 15 to drive the movable plate 10 to move away from the second guide tooth column 6. The buckle 16 separates from the limit groove formed by the second column teeth 23, and the second limit mechanism 8 releases the limit on the second guide tooth column 6. The lifting plate 3 falls to the lowest point under the action of gravity, waiting for the next transportation of the motor housing 20.

[0033] It should be noted that the stroke of the upper top cylinder 24, the tooth pitch of the first columnar tooth 22, and the tooth pitch of the second columnar tooth 23 need to meet the following dimensional matching requirements: when the lifting plate 3 is at the lowest point and the upper top cylinder 24 is at the minimum stroke, the buckle 16 of the first limiting mechanism 7 is just located at the highest point of the limiting groove formed by the first columnar tooth 22, and the buckle 16 of the second limiting mechanism 8 is just located at the lowest point of the limiting groove formed by the second columnar tooth 23; it can enable the device to return to the initial state faster when the lifting plate 3 descends to the lowest point. A limiting rod 19 is also provided between the fixed plate 2 and the lifting plate 3, and the length of the limiting rod 19 is used to determine the lowest point position of the lifting plate 3; by setting the specific length of the limiting rod 19, the above-mentioned dimensional matching requirements are completed.

[0034] Sleeve rods 18 are provided on both the first guiding tooth column 5 and the second guiding tooth column 6. Lubricating oil can be added into the sleeve rods 18 to reduce the sliding resistance and reduce the wear of the workpiece. Below the engaging portion 11 of the first limiting mechanism 7, the end of the bracket 4 is also in a semi-circular groove shape, which can provide an upward supporting force for the engaging portion 11 when the first limiting mechanism 7 drives the first guiding tooth column 5 to move upward, and improve the structural strength of the engaging portion 11 of the first limiting mechanism 7. The horizontal end of the right-angled plate of the positioning plate 9 of the second limiting mechanism 8 coincides with the end of the engaging portion 11, and the horizontal end of the right-angled plate of the positioning plate 9 is also in a semi-circular groove shape, which can provide a downward supporting force for the engaging portion 11 when the second limiting mechanism 8 fixes the lifting plate 3 from descending, and improve the structural strength of the engaging portion 11 of the second limiting mechanism 8.

[0035] Below the fixed plate 2, a support plate 21 is also fixedly connected to the vertical plate 1. The shape of the support plate 21 is a right-angled trapezoid, and the right-angled side is attached to the bottom surface of the fixed plate 2 to provide an upward supporting force for the fixed plate 2 and improve the structural strength of the fixed plate 2.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] However, the above are only specific embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the scope of protection of the present invention patent shall still fall within the scope covered by the claims of the present invention.
