[0001] The utility model relates to the technical field of grease removal equipment, and particularly relates to a grease removal tooling for box-shaped workpieces. Background Art

[0002] Between various transmission or moving parts, it is often necessary to set grease in their protective boxes to protect the moving parts. And in order to better protect the moving parts, during the later maintenance process, it is generally necessary to clean the old grease in the protective box and then install new clean grease. At present, the general method is to use an air gun to blow out the grease in the inner cavity of such boxes. However, during the process of blowing out with an air gun, the grease is likely to splash out from the box opening in all directions, which not only pollutes the surrounding environment but also is not conducive to the collection of the old grease. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a grease removal tooling for box-shaped workpieces that can prevent grease from splashing during the grease blowing process and facilitate the collection of the blown-out grease.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a grease removal tooling for box-shaped workpieces, including a bracket, a grease collection box, and a pressing mechanism. A support plate for cooperating with the box opening of the workpiece so that the workpiece can be reversely buckled and hermetically installed thereon is provided on the bracket. A through hole corresponding to the box opening of the workpiece reversely buckled on the support plate is provided inside the support plate.

[0005] The pressing mechanism is arranged above the support plate for pressing the workpiece downward and fixing it to be installed on the support plate.

[0006] The grease collection box is covered at the lower end of the through hole, and an exhaust port is provided on the grease collection box.

[0007] At least one blow pipe extending into the through hole is provided below the through hole for removing the grease in the workpiece reversely buckled on the support plate.

[0008] Further, the pressing mechanism includes a cantilever and a pressing block. One end of the cantilever is hinged to the bracket through a horizontal hinge shaft, the pressing block is installed at the other end of the cantilever, and a pressing spring for cooperating with the cantilever is provided on the bracket to make the cantilever rotate around the hinge shaft and thus make the pressing block press downward on the workpiece.

[0009] Further, a distance adjusting mechanism for adjusting the distance between the pressing block and the cantilever is provided on the cantilever, and the pressing block is installed at the other end of the cantilever through the distance adjusting mechanism.

[0010] Further, the distance adjusting mechanism includes a connecting rod slidably connected to the cantilever in a direction perpendicular to the cantilever. The pressing block is mounted at the lower end of the connecting rod, and a locking mechanism is provided on the connecting rod to cooperate with the cantilever to lock the relative position of the connecting rod.

[0011] Further, the connecting rod is slidably connected to the cantilever in a direction perpendicular to the cantilever through a through groove provided on the cantilever.

[0012] Further, the through groove extends along the extending direction of the cantilever, so that the connecting rod can slide along the extending direction of the cantilever through the through groove.

[0013] Further, an air collecting cavity is provided in the grease collecting box. An air inlet nozzle extending outside the grease collecting box is provided outside the air collecting cavity. The blowing pipes are multiple and arranged at intervals, and the lower ends of the blowing pipes are connected in parallel to the air collecting cavity.

[0014] Further, the exhaust port is provided on the side surface of the grease collecting box.

[0015] The beneficial effects of the present utility model are as follows: The grease removal tooling for box-shaped workpieces of the present utility model can be fixed on the support plate through the pressing mechanism when removing grease.

Detailed implementation mode

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] As Figure 1 、 Figure 2 shown, the grease removal tooling for box-shaped workpieces of the present utility model includes a bracket 1, a grease collection box 2, and a pressing mechanism 3. A support plate 11 for cooperating with the box opening of the workpiece 5 so that the workpiece 5 can be inverted and hermetically installed thereon is provided on the bracket 1. A through hole 12 corresponding to the box opening of the workpiece 5 inverted and installed on the support plate 11 is provided inside the support plate 11. The through hole 12 is used for dropping grease, and generally has the same size as the box opening of the workpiece 5. The pressing mechanism 3 is arranged above the support plate 11 to press the workpiece 5 downward and fix it on the support plate 11. The grease collection box 2 covers the lower end of the through hole 12, and an exhaust port is provided on the grease collection box 2. At least one blow pipe 4 extending into the through hole 12 is provided below the through hole 12 for removing the grease inside the workpiece 5 inverted and installed on the support plate 11.

[0024] As Figure 2 shown, when removing the grease from the workpiece, first invert the workpiece 5 on the support plate 11, and press the workpiece 5 downward through the pressing mechanism 3 to install and fix the workpiece on the support plate 11. At this time, the support plate 11 cooperates with the box opening of the workpiece 5 to hermetically cover the box opening of the workpiece 5 to prevent gas from passing between the workpiece and the support plate. After the workpiece is fixed, high-pressure gas is introduced into the blow pipe 4, and the high-pressure gas enters the inner cavity of the workpiece 5 through the blow pipe 4, thereby blowing out the grease inside the inner cavity of the workpiece 5. The blown-out grease enters the grease collection box 2 from the through hole 12 under the action of gravity and air flow, and is collected by the grease collection box 2. The gas after removing the grease is discharged from the exhaust port on the grease collection box 2. It can be understood that, in order to prevent the grease from being discharged from the exhaust port on the grease collection box 2, the exhaust port is generally arranged on the side of the grease collection box 2.

[0025] In order to enable the support plate 11 to better cooperate with the box opening of the workpiece 5 to seal the workpiece, a sealing rubber pad can be provided on the support plate 11.

[0026] For the grease removal tooling for box-shaped workpieces of the present utility model, when removing grease, it can be fixed on the support plate 11 through the pressing mechanism 3, and the grease removed by blowing will enter the grease collection box 2 through the through hole 12 and be collected by the grease collection box 2. Moreover, since the grease collection box 2 covers the lower end of the through hole 12, that is, covers it, it can prevent the grease from splashing everywhere during the removal process and prevent the grease from polluting the environment. Therefore, this tooling greatly improves the convenience of removing grease from box-shaped workpieces, improves the working environment of workers, and is convenient for the recycling and reuse of used grease.

[0027] The pressing mechanism 3 can adopt a hydraulic cylinder, a pneumatic cylinder, etc. In the present utility model, as Figure 3 described, the pressing mechanism 3 includes a cantilever 31 and a pressing block 32; one end of the cantilever 31 is hinged to the bracket 1 through a horizontal hinge shaft 33, so that the cantilever 31 can swing up and down around the hinge shaft 33, and the pressing block 32 is installed at the other end of the cantilever 31. A pressing spring 34 is provided on the bracket 1 and is configured to cooperate with the cantilever 31 to make the cantilever 31 rotate around the hinge shaft 33 and further press the pressing block 32 downward onto the workpiece 5. When this pressing mechanism is in use, the pressing spring 34 causes the cantilever 31 to rotate downward around the hinge shaft 33, thereby pressing down the pressing block 32 to press the workpiece and fix the workpiece on the support plate 11; and when the grease in the workpiece is cleaned up, the cantilever 31 can be rotated upward to take out the workpiece. The above pressing mechanism has a simple structure and low cost, and the cantilever 31 can be rotated, and the pressing block and the cantilever can be moved out from above the workpiece, which can prevent it from interfering with the installation and disassembly of the workpiece.

[0028] The pressing block 32 can be fixed to the cantilever in a non-adjustable position. Since the heights of different workpieces are often inconsistent, when the heights of the workpieces are different, if the position of the pressing block 32 is not adjustable, the contact angle between the pressing block 32 and the workpiece will be different, and it is difficult to ensure that the pressing block is in perpendicular contact with the workpiece, which will affect the pressing and fixing effect of the pressing block. In order to enable the pressing block to better contact the workpiece, in the present utility model, a distance adjusting mechanism for adjusting the distance between the pressing block 32 and the cantilever 31 is provided on the cantilever 31, and the pressing block 32 is installed at the other end of the cantilever 31 through the distance adjusting mechanism. In this way, according to the height of the workpiece, the distance between the pressing block 32 and the cantilever 31 can be adjusted accordingly through the distance adjusting mechanism, so that the pressing block can be at an appropriate height and vertically press on the workpiece, thereby better fixing the workpiece.

[0029] The distance adjusting mechanism can adopt a screw rod threadedly connected to the cantilever 31, or a telescopic mechanism, such as a pneumatic cylinder, a hydraulic cylinder, etc. In an embodiment of the present utility model, as Figure 4 shown, the distance adjusting mechanism includes a connecting rod 35 slidably connected to the cantilever 31 in a direction perpendicular to the cantilever 31. The pressing block 32 is installed at the lower end of the connecting rod 35, and a locking mechanism 36 is provided on the connecting rod 35 to cooperate with the cantilever 31 to lock the relative position of the connecting rod 35. When it is necessary to adjust the distance between the pressing block 32 and the cantilever 31, the connecting rod 35 is slid to an appropriate position, and then the position of the connecting rod 35 is locked by the locking mechanism 36. The locking mechanism 36 can specifically adopt a locking screw, a bolt, etc.

[0030] In the embodiment of the present utility model, a through groove 37 is provided on the cantilever 31, and the connecting rod 35 is inserted into the through groove 37 so as to be slidably connected to the cantilever 31 in a direction perpendicular to the cantilever 31 through the through groove 37. In some embodiments, a groove is provided on the side surface of the connecting rod 35, and a protrusion slidably engaged with the groove is provided on the side surface of the cantilever 31. The connecting rod 35 is slidably engaged with the cantilever 31 through the groove and the protrusion, so as to be slidably connected to the cantilever 31 in a direction perpendicular to the cantilever 31.

[0031] When the connecting rod 35 is slidably connected to the cantilever 31 in a direction perpendicular to the cantilever 31 through the through groove 37, the locking mechanism 36 can also be provided with compression nuts (see Figure 3 ) threadedly connected to the connecting rod 35 on both sides of the through groove 37.

[0032] The upper surface of the workpiece is uneven. In order to enable the pressing block 32 to select a suitable position to press the workpiece according to the actual shape of the upper surface of the workpiece. In the present utility model, the through groove 37 extends along the extending direction of the cantilever 31, so that the connecting rod 35 can slide along the extending direction of the cantilever through the through groove 37. In this way, according to the shape of the upper surface of the workpiece, the pressing block 32 can be moved along the through groove 37 to move the pressing block 32 to a position where it can better contact the workpiece and press the workpiece, so as to better fix the workpiece.

[0033] The air blowing pipe 4 can be one or more. When the air blowing pipe 4 is one, it can be arranged in the following Figure 5 way: The air blowing pipe 4 is inserted through the universal ball head 7 installed at the bottom of the grease collection box 2 and extends into the through hole 12, so that the air blowing pipe 4 can adjust the position of its air outlet through the universal ball head 7, and thus the air can be blown to remove grease from various parts inside the workpiece. In the embodiment of the present utility model, the air blowing pipe 4 is multiple and arranged at intervals. When the air blowing pipe 4 is multiple, the interval between the air blowing pipes 4 should ensure that there is a certain overlapping area in the cleaning coverage range of adjacent air blowing pipes, and all the air blowing pipes can finally form a full coverage of the inner cavity of the workpiece without dead corners that cannot be cleaned. The specific number of the air blowing pipes 4 can be calculated accordingly according to the size of the workpiece and the determined interval value. When the air blowing pipe 4 is multiple, generally, air is simultaneously introduced into the air blowing pipes 4 to exhaust air from the air blowing pipes 4 into the inner cavity of the workpiece at the same time, so as to more efficiently and thoroughly remove the grease inside the workpiece. As Figure 3 shown, in order to facilitate the simultaneous exhaust of air from all the air blowing pipes 4 into the inner cavity of the workpiece, optimally, a gas collecting cavity 6 is provided in the grease collection box 2, an air inlet nozzle 61 extending outside the grease collection box 2 is provided outside the gas collecting cavity 6, and the lower ends of the air blowing pipes are connected in parallel to the gas collecting cavity 6. In this way, only by connecting the air supply pipe to the air inlet nozzle 61, the air can be simultaneously supplied to all the air blowing pipes 4 through the air inlet nozzle 61 and the gas collecting cavity 6.
