Description

Technical Field

[0001] This utility model relates to the field of jack production technology, and in particular to a column grinding device for jack production that facilitates waste collection. Background Technology

[0002] In the production process of jacks, the column is the core load-bearing component. The smoothness and flatness of its surface directly affect the assembly accuracy, load-bearing performance and service life of the jack. Therefore, the grinding process in the production of the column is crucial.

[0003] Existing grinding devices typically use a fixed structure to secure the column. However, these fixed structures generally lack an automatic synchronous rotation mechanism. During grinding, the column must be manually rotated or turned to achieve all-around surface grinding. This not only significantly increases the labor intensity of operators but also easily leads to inconsistent grinding thickness on the column surface due to uneven rotation speed and angle deviations, resulting in over-grinding or under-grinding in certain areas, severely reducing grinding efficiency and the yield of finished products. Therefore, we provide a column grinding device for jack production that facilitates waste collection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a column grinding device for jack production that facilitates waste collection. It solves the technical problem that existing jack column grinding devices require manual rotation of the column, which increases labor intensity and easily leads to uneven grinding and reduced column grinding efficiency. The new device achieves automatic column rotation, eliminating the need for manual rotation and improving grinding efficiency and stability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a column grinding device for easy waste collection in jack production, including a collection seat installed in the middle of the base.

[0006] Two sets of load-bearing seats are bolted to the collection seat. A square frame is installed on the top of the load-bearing seat. Multiple sets of load-bearing rollers are rotatably connected to the bottom of the inner side of the square frame. One set of load-bearing rollers is connected to the output shaft of the drive motor. Fixed gears distributed on the outside of the square frame are installed on each set of load-bearing rollers. An auxiliary gear that meshes with the fixed gear is rotatably connected to the inside of the outside of the square frame.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Existing jack column grinding devices require manual rotation of the column, which increases labor intensity and can easily lead to uneven grinding, reducing grinding efficiency. This embodiment provides a jack production column grinding device that facilitates waste collection and can automatically drive the column to rotate, eliminating the need for manual rotation and improving grinding efficiency and stability. Please refer to... Figure 1 - Figure 5 The jack production column grinding device for easy waste collection includes a collection seat 2 installed in the middle of the base 1.

[0019] In the grinding operation of jack columns, existing grinding devices often use a fixed structure to fix the column. However, such fixed structures generally lack an automatic synchronous rotation mechanism. During grinding, the column must be manually flipped or rotated to achieve all-round grinding of its surface. This not only greatly increases the labor intensity of the operators, but also easily leads to inconsistent grinding thickness on the column surface due to uneven manual rotation speed and angle deviation. This results in problems such as over-grinding or under-grinding in some areas, reducing the grinding efficiency and the finished product qualification rate. In order to solve the above problems...

[0020] Two sets of load-bearing seats 3 are bolted to the collecting base 2. A square frame 4 is installed on the top of the load-bearing seat 3. Multiple sets of load-bearing rollers 5 are rotatably connected to the bottom of the inner side of the square frame 4. One set of load-bearing rollers 5 is connected to the output shaft of the drive motor 6. The load-bearing rollers 5 are made of silicone. Silicone has elasticity and anti-slip properties, which can reduce hard friction on the surface of the column to avoid damage. It can also increase the friction with the column to prevent the column from slipping and ensure the column rotates stably. Each set of load-bearing rollers 5 is equipped with fixed gears 7 distributed on the outside of the square frame 4. An auxiliary gear 8 that meshes with the fixed gear 7 is rotatably connected to the inside of the outside of the square frame 4. The auxiliary gear 8 is distributed between the two sets of fixed gears 7 and can transmit power to make the multiple sets of load-bearing rollers 5 rotate synchronously to ensure that the column rotates at a uniform speed.

[0021] The square frame 4 has through support grooves 9 on both sides. The top of the square frame 4 is threaded with a lead screw 10. The bottom of the lead screw 10 is hinged to a connecting frame 11 that is slidably connected to the inside of the support groove 9. The connecting frame 11 is rotatably connected to multiple sets of limiting rollers 12 that correspond to the positions of the load-bearing rollers 5.

[0022] Two sets of load-bearing seats 3 are installed on the collecting seat 2 by bolts. The column is placed on multiple sets of load-bearing rollers 5. By rotating the lead screw 10, the connecting frame 11 is lowered under the support of the support groove 9, thereby limiting the column with the limiting roller 12, thus fixing the column and improving the grinding stability of the column. The operation of the drive motor 6 drives a set of load-bearing rollers 5 to rotate. Under the mutual meshing of the fixed gear 7 and the auxiliary gear 8, all load-bearing rollers 5 rotate synchronously. Then, under the limitation of the limiting roller 12, the column is driven to rotate automatically, thereby improving the grinding efficiency of the column.

[0023] Example 2 Based on Example 1, such as Figure 1 - Figure 5 As shown, the existing jack column grinding device requires manual rotation of the column, which increases labor intensity and is prone to uneven grinding due to manual rotation, thus reducing the grinding efficiency of the column. However, the existing grinding device lacks a structure for handling debris, which easily leads to debris accumulation after long-term grinding and affects the grinding accuracy of the column. Therefore, this device is also equipped with a structure for cleaning and collecting debris.

[0024] In the grinding operation of jack columns, the existing grinding equipment lacks a dedicated chip handling structure, which easily leads to chip accumulation after long-term grinding. The accumulated chips directly affect the grinding accuracy of the column. In order to solve the above problems...

[0025] An L-frame 13 is installed on one side of the top of the collecting base 2. An asynchronous motor 14 is installed on the upper side of the L-frame 13. A lead screw 15 is installed on the output shaft of the asynchronous motor 14. A movable base 16 is threadedly connected to the lead screw 15 and slidably connected to the slide rod installed on the upper inner side of the L-frame 13. An electrically controlled lifting rod 17 is installed at the bottom of the movable base 16. A connecting plate 18 is installed at the telescopic end of the electrically controlled lifting rod 17. A grinder 19 is installed at the bottom of the connecting plate 18.

[0026] A vacuum cleaner 20 is installed at the top of the L-frame 13. The vacuum heads 21 distributed on both sides of the grinder 19 are installed inside the connecting plate 18. The two sets of vacuum heads 21 are connected to the vacuum cleaner 20 by a connecting pipe 22.

[0027] An electric push rod 23 is installed on the back of the collection seat 2. The telescopic end of the electric push rod 23 is equipped with a push plate 24 distributed inside the collection seat 2. A guide groove 25 is opened at the bottom of the collection seat 2, which extends into the base platform 1. Long guide plates 26 and short guide plates 27 are respectively installed at the top of the base platform 1, corresponding to the position of the guide groove 25. A collection box 28 is provided at the bottom of the base platform 1, distributed below the long guide plate 26 and the short guide plate 27.

[0028] The asynchronous motor 14 on the upper side of the L-frame 13 starts, driving the lead screw 15 on the output shaft to rotate. The movable seat 16 threaded on the lead screw 15 slides along the slide bar on the upper inner side of the L-frame 13 to adjust the grinding position. The electrically controlled lifting rod 17 at the bottom of the movable seat 16 extends and retracts, driving the connecting plate 18 and the grinder 19 at the bottom to rise and fall, so that the grinder 19 contacts the column to complete the grinding operation.

[0029] While grinding, the vacuum cleaner 20 at the top of the L-frame 13 operates, connecting two sets of vacuum heads 21 via a connecting pipe 22. The vacuum heads 21 absorb the tiny debris generated during grinding. Since the top of the collection seat 2 has a matrix-style collection hole, larger debris can fall into the collection seat 2. The electric push rod 23 on the back of the collection seat 2 extends and retracts, driving the pusher plate 24 at its extension end to move inside the collection seat 2, pushing the larger debris towards the guide channel 25 at the bottom of the collection seat 2. The guide channel 25 extends into the base platform 1. Long guide plates 26 and short guide plates 27, distributed front and back, are installed at the top of the base platform 1 corresponding to the position of the guide channel 25. The debris falls through the guide channel 25 and, guided by the long guide plates 26 and short guide plates 27, finally falls into the collection box 28 at the bottom of the base platform 1, achieving centralized collection of waste.
