Description

Technical Field

[0001] This utility model relates to the field of resin sand cleaning technology, and in particular to a pneumatic pick sand removal machine. Background Technology

[0002] Currently, aluminum alloy casting uses sand casting. After the casting process is completed, the resin sand in the sand box needs to be cleaned out before it can be reshaped and reused. At present, sand box cleaning is done by using an overhead crane to lift the sand box and workers to clean it bit by bit with electric picks and steel chisels. This is labor-intensive and time-consuming, and it is difficult to meet the requirements of mass production. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model provides a pneumatic pick sand removal machine, which mainly solves the problem of low sand box cleaning efficiency in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pneumatic pick sand removal machine includes a chassis, a support, a movable base, a worktable, a positioning mechanism, a pneumatic pick, a first guide mechanism, a second guide mechanism, and a lifting drive mechanism. The length of the chassis is defined as the transverse direction, the width as the longitudinal direction, and the height as the vertical direction. The chassis has an operating opening. The interior of the chassis has a sand removal trough communicating with the outside. The worktable is mounted inside the chassis via the support and is positioned above the sand removal trough. The positioning mechanism is mounted on the worktable for fixing the sand box. The first guide mechanism is located on the upper part of the support and is distributed in the transverse direction. The movable base is mounted on the first guide mechanism. The second guide mechanism is mounted on the movable base and is distributed in the longitudinal direction. The lifting drive mechanism is mounted on the second guide mechanism. The pneumatic pick is located at the lower end of the lifting drive mechanism and is positioned above the positioning mechanism.

[0006] Furthermore, it also includes a filtering mechanism. The support is mounted on a baffle located on the rear side of the workbench. The baffle has multiple through holes. The filtering mechanism is located on the back of the baffle. The filtering mechanism has a negative pressure adsorption port and an exhaust port. The negative pressure adsorption port is connected to each through hole.

[0007] Furthermore, the positioning mechanism includes a positioning frame fixed on the workbench, multiple positioning holes on the positioning frame, and at least three positioning components. The positioning components include a base, a clamping seat, and a bolt. The clamping seat and the base are both provided with connecting holes in the middle. The bolt passes through the connecting holes of the clamping seat and the base and is threadedly connected to the positioning holes. The sand box is clamped and fixed by the base and the clamping seat.

[0008] Furthermore, the first guiding mechanism includes guide grooves recessed on both longitudinal sides of the upper surface of the bracket and rollers disposed on the movable seat. The two guide grooves are distributed in the transverse direction, the guide grooves have a supporting surface, and the rollers abut against the supporting surface.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This pneumatic pick sand removal machine has a worktable for placing sand boxes, a positioning mechanism for fixing the sand boxes, a first guiding mechanism for moving the pneumatic pick in the horizontal direction, a second guiding mechanism for moving the pneumatic pick in the vertical direction, and a lifting drive mechanism for moving the pneumatic pick in the vertical direction. This allows the pneumatic pick to move flexibly in three-dimensional space to clean the resin sand in different locations within the sand box. Compared to the existing technology where workers use electric picks and steel chisels to clean the sand box bit by bit, this greatly improves the efficiency of sand box cleaning and can meet the requirements of batch casting production schedules.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] The embodiment of this utility model is as follows:

[0017] refer to Figures 1 to 5As shown, a pneumatic pick sand removal machine includes a housing 1, a support 2, a movable base 3, a worktable 4, a positioning mechanism 5, a pneumatic pick 6, a first guide mechanism 7, a second guide mechanism 8, and a lifting drive mechanism 9. The lifting drive mechanism 9 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, preferably a pneumatic cylinder. It is defined as extending laterally along the length of the housing 1, longitudinally along the width of the housing 1, and vertically along the height of the housing 1. The housing 1 has an operating port 10, and the interior of the housing 1 has a sand removal trough 11 communicating with the outside. The workbench 4 is mounted inside the housing 1 via the bracket 2 and is located on the upper side of the sand drop trough 11. The positioning mechanism 5 is mounted on the workbench 4 and is used to fix the sand box. The first guide mechanism 7 is located on the upper part of the bracket 2 and is distributed in the horizontal direction. The movable seat 3 is mounted on the first guide mechanism 7. The second guide mechanism 8 is mounted on the movable seat 3 and is distributed in the vertical direction. The lifting drive mechanism 9 is mounted on the second guide mechanism 8. The pneumatic pick 6 is located at the lower end of the lifting drive mechanism 9 and is located on the upper side of the positioning mechanism 5.

[0018] This pneumatic pick sand removal machine has a worktable 4 for placing sand boxes, a positioning mechanism 5 for fixing the sand boxes, a first guide mechanism 7 for moving the pneumatic pick 6 in the horizontal direction, a second guide mechanism 8 for moving the pneumatic pick 6 in the vertical direction, and a lifting drive mechanism 9 for moving the pneumatic pick 6 in the vertical direction. This allows the pneumatic pick to move flexibly in three-dimensional space to clean the resin sand in different locations within the sand box. Compared to the existing technology where workers use electric picks and steel chisels to clean the sand box bit by bit, this greatly improves the efficiency of sand box cleaning and can meet the requirements of batch casting production schedules.

[0019] Furthermore, it also includes a filter mechanism 13, which is mounted on the support 2 and located on the rear side of the workbench 4, on a baffle 14. The baffle 14 has multiple through holes 15, and the filter mechanism 13 is located on the back of the baffle 14. The filter mechanism 13 has a negative pressure adsorption port and an exhaust port 131. The negative pressure adsorption port is connected to each through hole 15. During the cleaning of the sand box, dust and other impurities generated can be drawn into the filter mechanism 13 through the through holes 15 by the negative pressure adsorption port, and discharged from the exhaust port 131 after filtration. This effectively reduces the spread of dust during the cleaning process, improves the working environment, protects the health of operators, and also avoids dust pollution of the surrounding environment.

[0020] Specifically, the positioning mechanism 5 includes a positioning frame 51 fixed on the workbench 4, multiple positioning holes 52 on the positioning frame 51, and four positioning components 53. Each positioning component 53 includes a base 531, a clamping seat 532, and a bolt (not shown in the figure). The clamping seat 531 and the base 532 each have a connecting hole 533 in the middle. The bolt passes through the connecting hole 533 of the clamping seat 531 and the base 532 and is threadedly connected to the positioning hole 52. The sand box is clamped and fixed by the base 531 and the clamping seat 532. This positioning mechanism 5 has a simple structure and is easy to operate. By clamping and fixing the sand box from different positions through multiple positioning components 53, it can ensure that the sand box remains stable during the cleaning process and will not move or shake due to the impact of the pneumatic pick. This improves the accuracy and stability of the cleaning and further ensures the cleaning effect and the safety of the equipment.

[0021] Furthermore, the first guide mechanism 7 includes guide grooves 71 recessed on both longitudinal sides of the upper surface of the bracket 2 and rollers 72 disposed on the movable seat 3. The two guide grooves 71 are distributed in the transverse direction. The guide grooves 71 have a support surface 711. The rollers 72 abut against the support surface 711, so that when the movable seat 3 moves laterally, the rollers 72 roll on the support surface 711 of the guide grooves 71, reducing the friction during the movement, making the movement smoother and more stable, reducing the wear of the equipment, improving the service life of the equipment, and also ensuring the accuracy of the jackhammer's movement in the transverse direction, which is conducive to improving the quality of sand box cleaning. The second guide mechanism 8 is consistent with the first guide mechanism 7.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
