Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a drum type polishing machine. Background Art

[0002] During the machining process, many parts are prone to forming thorns or flash on the edges of the parts after they are just machined, which is usually called burrs. Although the volume of burrs is not large, it does directly affect the quality of the product. Therefore, with the attention paid to burr removal in various industries, the methods of deburring are constantly innovating. In the prior art, the deburring mechanism is mostly a roller. When in use, the finished workpiece is placed in the roller. At the same time, mud and sand are placed in the roller. Under the action of the rotation of the roller, the friction between the workpiece and the mud and sand is used to remove the burrs.

[0003] Existing drum polishing machines usually have doors on the side walls, but due to the limitations of space and the operating status of the drum, in general, the connection between the door and the drum is not a hinged structure, but more of a sliding connection or a detachable connection structure, including the sliding connection door opening method, which also needs to be fixed after opening the door to prevent affecting the discharge. At present, the methods of sliding door opening or manual removal of door panels need to be implemented manually at this stage. In addition, since the drum opening needs to be downward to allow the material to slide freely during discharge, it is necessary to stop the machine when the drum opening is placed at the top, and restart the machine after the door is manually opened. Because the load in the drum is large, repeated starting and stopping of the equipment will undoubtedly cause a large load on the power equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a drum polishing machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, a technical solution adopted by the utility model is: a drum polishing machine, comprising a drum body, a door panel and a frame for fixing the drum body, the door panel is slidably connected to the drum body, the drum body is provided with a door opening assembly for continuously applying a force to the door panel to open it, the drum body is also provided with a blocking assembly for preventing the door panel from opening, the resistance applied by the blocking assembly to the door panel is not less than the force applied by the door opening assembly to the door panel to open it, and the polishing machine is provided with a door opening intervention assembly for reducing the resistance applied by the blocking assembly to the door panel, the door opening intervention assembly makes the resistance applied by the blocking assembly to the door panel less than the force continuously applied by the door opening assembly to the door panel to open it, thereby realizing the opening of the door panel.

[0006] Preferably, the door opening assembly includes a guide rail module fixed on the door opening direction of the drum body and an elastic member arranged in the guide rail module. The door panel is slidably connected in the guide rail module. The door panel is provided with a force-bearing portion for bearing the elastic force of the elastic member. The elastic force of the elastic member can make the door panel fully open.

[0007] Preferably, the blocking assembly includes a fixed sleeve and a block that can slide therein, and a load-bearing member is fixed on the door panel. When the block extends out of the fixed sleeve, the block conflicts with the load-bearing member and prevents it from moving along the direction in which the guide rail module is set to open the door panel.

[0008] Preferably, a sliding protrusion is provided on the block, and the door opening intervention assembly includes a wedge block and a control cylinder that controls the wedge block to move onto the movement trajectory of the sliding protrusion. When the door panel needs to be opened, the control cylinder controls the wedge block to move onto the movement trajectory of the sliding protrusion, and the sliding protrusion contacts the wedge block and moves along the inclined surface of the wedge block, thereby causing the block to slide in the fixed sleeve until the block no longer blocks the load-bearing member, and then the sliding protrusion disengages from the wedge block.

[0009] Preferably, a second elastic member is provided in the fixing sleeve for continuously applying force to the stopper to make it extend out of the fixing sleeve.

[0010] Preferably, when the door panel slides along the guide rail module to close the opening of the drum body, the surface of the stopper that the load-bearing member contacts is an arc-shaped surface.

[0011] Preferably, the guide rail module is provided with a limiting member for preventing the door panel from separating from the guide rail module.

[0012] Preferably, a handle is provided on the door panel.

[0013] Beneficial effects of the utility model: the solution realizes the closing of the door panel by the resistance exerted by the blocking component on the door panel. When the door needs to be opened, the force exerted by the door opening component on the door panel is sufficient to open the door panel through the intervention of the door opening intervention component. The equipment does not need to be shut down for operation during the whole process, which improves the discharge efficiency and prolongs the service life of the equipment.

[0014] Among them, the door panel can be opened automatically without resistance through the joint action of the guide rail module and the elastic member; the blocking effect on the opening of the door panel is achieved through the action of the fixed sleeve and the stopper; the contraction of the stopper is achieved through the friction between the sliding protrusion on the stopper and the wedge block, thereby achieving the effect of opening the door panel;

[0015] Among them, by setting up the second elastic member, it can be achieved that when the door panel is reset and closed, it is only necessary to control the movement of the door panel so that the load-bearing member can be engaged with the block again to complete the closing of the door panel, and when the door panel is set to slide along the guide rail module to close the opening of the roller body, the surface of the block that the load-bearing member contacts is an arc-shaped surface, which makes it easier for the load-bearing member to move the block and be engaged by the block.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] Example:

[0027] See also Figure 1 , Figure 2 , a drum polishing machine comprises a drum body 2, a door panel 3 and a frame 1 for fixing the drum body 2, the drum body 2 is a multi-prism drum, the door panel 3 is slidably connected to one surface of the drum body 2, and a door opening component is arranged on the surface of the drum body 2 where the door panel 3 is arranged, which continuously applies a force to the door panel 3 to open it. The drum body 2 is also provided with a blocking component 5 for preventing the door panel 3 from opening, and the resistance applied by the blocking component 5 to the door panel 3 is not less than the force applied by the door opening component to the door panel 3 to open the door panel 3, and a door opening intervention component 6 for reducing the resistance applied by the blocking component 5 to the door panel 3 is arranged on the frame 1, and the door opening intervention component 6 makes the resistance applied by the blocking component 5 to the door panel 3 less than the force continuously applied by the door opening component to the door panel 3 to open it, thereby realizing the opening of the door panel 3, wherein a handle 33 is arranged on the door panel 3 to facilitate closing the door.

[0028] For details, see Figure 2-Figure 5 The door opening assembly includes a guide rail module 4 fixed to the door opening direction of the drum body 2 and an elastic member 43 arranged in the guide rail module 4. The guide rail module 4 includes a set of corresponding guide rails 41 and a guide rail 42 fixed on the guide rail 41. The elastic member 43 is arranged in the guide rail 42. The door panel 3 is inserted into the guide rail 41 and slides in the guide rail 41. The length of the guide rail 41 is greater than the stroke of the door panel 3. A stopper 44 is arranged at the top of the guide rail 41 to prevent the door panel 3 from opening. After detaching from guide rail 1 41, the limiting member 44 can be a bolt that is screwed into the temporal part of guide rail 1 41. Two limiting sliders 31 are fixed on the door panel 3. Each limiting slider 31 slides in a guide rail 2 42. At the same time, the bottom surface of the limiting slider 31 contacts the top of the elastic member 2 54 and is subjected to the elastic force of the elastic member 2 54. The elastic member 2 54 can be a spring, etc. It should be noted that when designing, it is necessary to ensure that the length of guide rail 1 41 and guide rail 2 42 will not scratch the bracket, etc.

[0029] See also Figure 2 , Figure 3 , Figure 6 and Figure 7The blocking assembly 5 includes a fixed sleeve 52 and a stopper 53 that can slide therein. The fixed sleeve 52 is fixed on a fixed plate 51, and the fixed plate 51 is fixed on the drum body 2. An elastic member 54 is provided in the fixed sleeve 52 for continuously applying force to the stopper 53 to make it extend out of the fixed sleeve 52. One end of the elastic member can be fixed in the fixed sleeve 52 and the other end of the elastic member can be fixed to the stopper 53 to prevent the stopper 53 from detaching. The elastic member 54 can be a spring, etc. A load-bearing member 32 is fixed on the door panel 3. When the stopper 53 extends out of the fixed sleeve 52, the stopper 53 conflicts with the load-bearing member 32 and hinders it from moving along the direction in which the guide rail module 4 is set to open the door panel 3. When the door panel 3 slides along the guide rail 41 to close the opening of the drum body 2, the surface of the stopper 53 that the load-bearing member 32 contacts is an arc surface.

[0030] See also Figure 2 , Figure 3 and Figure 8 A sliding protrusion 55 is arranged on the block 53, wherein the door opening intervention component 6 includes a wedge block 63 and a control cylinder 62 for controlling the wedge block 63 to move to the movement trajectory of the sliding protrusion 55, and the control cylinder 62 is fixed to the bracket through a fixing seat 61. When the door panel 3 needs to be opened, the control cylinder 62 controls the wedge block 63 to move to the movement trajectory of the sliding protrusion 55, and the sliding protrusion 55 contacts the wedge block 63 and moves along the inclined surface of the wedge block 63, thereby making the block 53 slide in the fixing sleeve 52 until the block 53 no longer blocks the load-bearing member 32, and then the sliding protrusion 55 disengages from the wedge block 63.

[0031] Working principle and process:

[0032] When using the present equipment, the door panel 3 is opened by manually or starting the equipment through the cooperation of the control cylinder 62 and the wedge block 63. Subsequently, after adding materials into the drum body 2, the handle 33 is pulled to close the door panel 3. Subsequently, the equipment is started for processing. After the processing time is sufficient, the control cylinder 62 is started to control the wedge block 63 to fall into the running track of the sliding protrusion 55. When the sliding protrusion 55 moves to the position of the wedge block 63, it will move along the guide inclined surface of the wedge block 63 and pull the stop block 53 to retract into the fixed sleeve 52. At this time, under the action of the elastic member 1 43, the limit slider 31 moves along the guide rail 2 42 to open the door panel 3. Then, the control cylinder 62 is controlled to drive the wedge block 63 to retract. At this time, the drum body 2 is still in operation, and the materials therein will slowly fall along the opening of the drum body 2. After the drum body 2 rotates continuously for several circles, the materials therein can all leave the drum body 2, thus completing the entire processing process.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
