Description

Technical Field

[0001] This utility model belongs to the field of metering box production technology, and in particular relates to a metering box limiting groove tooling mold. Background Technology

[0002] In the industrial manufacturing sector, the cleanliness of the cavity of the measuring box, a key component of precision instruments and equipment, directly affects the molding accuracy. With the increasing demand for automated production, traditional manual cleaning methods can no longer meet the requirements of high precision and high frequency cleaning.

[0003] In existing technologies, cleaning the metering box limit groove mainly relies on air gun blowing, but this method suffers from problems such as secondary pollution from residues and blind spots in cleaning complex grooves. Furthermore, some mechanical cleaning devices use fixed brushes, which, while covering some areas, are difficult to adapt to the size variations of limit grooves of different specifications and lack dynamic airflow-assisted cleaning functions, resulting in low cleaning efficiency. Therefore, we provide a tooling mold for metering box limit grooves to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a metering box limiting groove tooling mold, which solves the problem of poor cleaning effect of the existing metering box limiting groove tooling mold through the cooperation of the cleaning mechanism and the blowing mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a measuring box limiting groove tooling mold, including an upper mold and a lower mold. A hydraulic push rod is fixedly connected to the left side of the upper mold via a mounting plate, and a support plate is fixedly connected to the top of the hydraulic push rod. A cleaning mechanism is provided on one side of the support plate. The cleaning mechanism includes a housing fixedly connected to one side of the support plate, a drive motor fixedly connected to the inner cavity of the housing, a reciprocating lead screw fixedly connected to the output shaft of the drive motor, a threaded sleeve sleeved on the surface of the reciprocating lead screw, a rotating shaft movably connected to the surface of the threaded sleeve via a bearing seat, and a cleaning roller fixedly connected to one end of the rotating shaft. A blowing mechanism is provided on the surface of the rotating shaft. The blowing mechanism includes a first synchronous pulley fixedly connected to the surface of the rotating shaft, a second synchronous pulley driven by the surface of the first synchronous pulley via a synchronous belt, and a fan blade fixedly connected to the axis of the second synchronous pulley.

[0007] The present invention is further configured such that a limiting groove adapted to the rotating shaft is provided on one side of the chassis, and a toothed plate is fixedly connected to the inner side of the limiting groove.

[0008] The present invention is further configured such that a gear is engaged on one side of the toothed plate, and the gear shaft is fixedly connected to the surface of the rotating shaft. The toothed plate and the gear form a precise meshing. When the rotating shaft moves axially, the structure converts the rotational motion into linear motion through the meshing of the gear and toothed plate, forming a spiral cleaning trajectory.

[0009] The present invention is further configured such that an L-shaped bracket is slidably connected to the surface of the chassis, and a sliding groove adapted to the L-shaped bracket is provided on the top of the chassis. The fan blade is movably connected to the inner wall of the L-shaped bracket through a bearing seat. The L-shaped bracket and the sliding groove form a low-friction sliding pair to ensure that the fan blade axis is always parallel to the rotating shaft.

[0010] The present invention is further configured such that a funnel cylinder is fixedly connected to one side of the L-shaped bracket, and a blowpipe is connected to the other end of the funnel cylinder. The funnel cylinder is designed with a large air inlet and a small air outlet on one side, which accelerates the airflow according to Bernoulli's principle. The inner wall of the blowpipe is provided with a spiral guide groove so that the airflow forms a rotating jet, thereby improving the cleaning efficiency.

[0011] The present invention is further configured such that a guide plate is provided on the surface of the blow pipe, the guide plate is inclined at a certain angle to the horizontal plane, the airflow generated by the fan blade is accelerated by the funnel cylinder and sprayed out from the inclined guide plate, forming an airflow orthogonal to the cleaning direction, effectively removing metal shavings embedded in the bottom of the groove.

[0012] The present invention is further provided that the surface of the cleaning roller is provided with a soft brush, which reduces the risk of scratching the mold surface while ensuring cleaning power.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model utilizes the synergistic effect of a gear tooth plate meshing transmission mechanism and a reciprocating lead screw to enable the cleaning roller to form a spiral propulsion cleaning trajectory. Combined with the high-speed rotating airflow ejected by the air guide plate, it achieves rapid removal of debris. The soft brush of the cleaning roller and the airflow ejected by the fan blades form an orthogonal interaction. After the soft brush removes the surface attachments, the high-speed airflow blows away the remaining debris in a directional manner, improving the debris removal rate at the bottom of the deep trough.

[0015] 2. This utility model uses a support plate to drive the machine box to move up and down, adapting to limit slots of different heights, avoiding frequent tooling changes. The double-headed trapezoidal thread design enables rapid reciprocating motion, and with the synchronous wheel drive, ensures the time and space synchronization of the blowing and cleaning actions.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5This utility model is a measuring box limiting groove tooling mold, including an upper mold 1 and a lower mold 2. A hydraulic push rod 3 is fixedly connected to the left side of the upper mold 1 through a mounting plate, and a support plate 4 is fixedly connected to the top of the hydraulic push rod 3. A cleaning mechanism is provided on one side of the support plate 4. The cleaning mechanism includes a housing 5 fixedly connected to one side of the support plate 4, a drive motor 6 fixedly connected to the inner cavity of the housing 5, a reciprocating lead screw 7 fixedly connected to the output shaft of the drive motor 6, a thread sleeve 8 sleeved on the surface of the reciprocating lead screw 7, a rotating shaft 9 movably connected to the surface of the thread sleeve 8 through a bearing seat, and a cleaning roller 10 fixedly connected to one end of the rotating shaft 9. A blowing mechanism is provided on the surface of the rotating shaft 9. The blowing mechanism includes a first synchronous wheel 11 fixedly connected to the surface of the rotating shaft 9, a second synchronous wheel 12 driven by the first synchronous wheel 11 through a synchronous belt, and a fan blade 13 fixedly connected to the axis of the second synchronous wheel 12.

[0027] Further details: The hydraulic push rod 3 can drive the housing 5 to move up and down through the support plate 4, and adjust the blowing and cleaning height within the set range to adapt to the cleaning needs of different specifications of limit grooves 14. The reciprocating screw 7 adopts a double-headed trapezoidal thread, which can achieve rapid reciprocating within a limited stroke. It works with the drive motor 6 to achieve high-precision positioning. The L-shaped bracket 17 has a through groove on one side, and its inner cavity is equipped with a dustproof net to ensure that during the process of the fan blade 13 rotating to generate negative pressure, the external gas is accelerated through the fan blade 13 and sprayed out from the air guide plate 21, effectively blowing away the fine debris in the groove.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a limiting groove 14 adapted to the rotating shaft 9 is provided on one side of the housing 5. A toothed plate 15 is fixedly connected to the inner side of the limiting groove 14. A gear 16 meshes with one side of the toothed plate 15. The shaft of the gear 16 is fixedly connected to the surface of the rotating shaft 9. An L-shaped bracket 17 is slidably connected to the surface of the housing 5. A sliding groove 18 adapted to the L-shaped bracket 17 is provided on the top of the housing 5. The fan blade 13 is movably connected to the inner wall of the L-shaped bracket 17 through a bearing seat. A funnel cylinder 19 is fixedly connected to one side of the L-shaped bracket 17. A blower pipe 20 is connected to the other end of the funnel cylinder 19. A guide plate 21 is provided on the surface of the blower pipe 20. The guide plate 21 is inclined at a certain angle to the horizontal plane. A soft brush 22 is provided on the surface of the cleaning roller 10.

[0030] Further details: The toothed plate 15 and the gear 16 form a precise meshing. When the rotating shaft 9 moves axially, the rotational motion is converted into linear motion through the meshing of the gear 16 and the toothed plate 15, forming a spiral cleaning trajectory. The L-shaped bracket 17 and the slide groove 18 form a low-friction sliding pair, ensuring that the axis of the fan blade 13 is always parallel to the rotating shaft 9. The funnel cylinder 19 is designed with a large air inlet and a small air outlet on one side. Based on Bernoulli's principle, the airflow is accelerated. The inner wall of the blow pipe 20 is provided with a spiral guide groove, which makes the airflow form a rotating jet, improving cleaning efficiency. The airflow generated by the fan blade 13 is accelerated by the funnel cylinder 19 and sprayed out from the inclined air guide plate 21, forming an airflow orthogonal to the cleaning direction, effectively removing metal shavings embedded in the bottom of the groove. The soft brush 22 reduces the risk of scratching the mold surface while ensuring cleaning power.

[0031] The working principle of this utility model is as follows: After the upper mold 1 and the lower mold 2 complete the stamping operation, the hydraulic push rod 3 can drive the machine box 5 to move upward through the support plate 4. The output shaft of the drive motor 6 drives the reciprocating screw 7 to rotate. The thread sleeve 8 moves back and forth along the stroke of the reciprocating screw 7. The thread sleeve 8 drives the cleaning roller 10 to move through the rotating shaft 9. At the same time, with the cooperation of the toothed plate 15 and the gear 16, the cleaning roller 10 performs a transverse scan while rotating.

[0032] At this time, the rotating shaft 9 drives the fan blade 13 to rotate at high speed through the first synchronous pulley 11, the synchronous belt and the second synchronous pulley 12, so that the fan blade 13 generates dynamic wind pressure. After the airflow is accelerated by the funnel cylinder 19, it forms a directional airflow with an inclination through the air guide plate 21 of the blow pipe 20. During the movement, the L-shaped bracket 17 slides synchronously in the slide groove 18 to ensure that the blow airflow is always aligned with the cleaning area behind the cleaning roller 10, ensuring the cleaning effect while ensuring cleaning efficiency.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
