Technical Field

[0001] The utility model relates to the technical field of machine tools, and particularly relates to an in-built handrail of a processing machine tool. Background Art

[0002] When loading and unloading materials on a precision engraving machine tool, generally, a person stands with both feet outside, bends down and enters the door opening to load and unload materials, or steps into the door with one foot, but the body is also inclined forward. In order to support the upper body, one hand often supports the workbench or the sliding door. The force application methods of these two points are not ideal, and it will also cause the door to be stained with oil stains, affecting the appearance of the machine tool. Content of the Utility Model

[0003] The problem solved by the utility model is that in the prior art, there is a suitable force application point in the precision engraving machine, which easily causes the door to be stained with oil stains when personnel load and unload materials. The utility model provides an in-built handrail of a processing machine tool.

[0004] The utility model is realized by the following technical solutions. An in-built handrail of a processing machine tool is installed on the side wall close to the door opening inside the machine tool, and includes a cross bar for connection and a longitudinal bar for an operator to hold. There are multiple cross bars, and the multiple cross bars and the longitudinal bar are connected as a whole, and the cross bar is connected to the side wall.

[0005] Further, the cross bar and the side wall are connected by welding or bolt fixation.

[0006] Further, a rotating shaft is also arranged between the cross bar and the side wall. The rotating shaft is fixedly connected to the cross bar, the upper and lower ends of the rotating shaft are rotatably connected to the side wall, and a limiting mechanism is arranged between the rotating shaft and the side wall. The handrail can rotate within an angle range of 90° from perpendicular to the side wall to pointing to the door opening.

[0007] Further, an elastic component is arranged on the rotating shaft, which can keep the rotating shaft in a state perpendicular to the side wall without power.

[0008] Further, an elastic component is arranged on the rotating shaft, which can keep the rotating shaft in a state pointing to the door opening without power.

[0009] Further, a rectangular groove is arranged on the side wall, and the handrail is arranged in the groove. When the handrail rotates to be perpendicular to the side wall, the cross bar abuts against the side surface of the groove, and the side surface of the groove constitutes the limiting mechanism. When the handrail rotates to point to the door opening, the cross bar abuts against the bottom surface of the groove, and the upper and lower ends of the rotating shaft are respectively rotatably connected to the upper and lower surfaces of the groove.

[0010] Furthermore, a gear is installed on the top of the rotating shaft, and a mounting frame is provided inside the machine tool. A rack is slidably provided on the mounting frame. The rack is horizontally arranged and parallel to the side wall. The rack is meshed with the gear. A wedge-shaped surface is provided at one end of the rack. A wedge block is fixedly installed on the upper end of the machine tool door, and a hole for accommodating the entry of the wedge block is provided on the side panel of the door opening. The wedge block can fit with the wedge-shaped surface of the rack.

[0011] Furthermore, the elastic component is a spring or a torsion spring.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model is provided with an armrest on the inner side of the machine tool door opening. When loading and unloading materials, the machine tool operator can hold the longitudinal rod with one hand and then lean over to enter the machine tool, so that there is a better fulcrum and the other hand can load and unload materials. It is convenient for loading and unloading small parts (hundreds of shells to several kilograms) processed by precision engraving machine tools, improves safety performance, improves operation convenience, and avoids the problem of oily hands touching the sliding door, thereby staining the door with oil stains and affecting the appearance of the machine tool.

[0014] 2. The utility model is provided with a rotating shaft and an elastic component, which can keep the handrail pointing to the door opening without power, and can be manually unfolded when needed to avoid obstruction or interference during processing.

[0015] 3. The utility model is provided with a rectangular groove on the side wall. When loading and unloading materials are not in progress, the handrail automatically fits into the groove, making the side wall relatively flat, without protrusions, more beautiful, safer, and less likely to cause interference.

[0016] 4. The utility model further adds gears and racks, and a wedge block is installed on the machine tool door. When the door is open, the torsion spring drives the armrest to open automatically, vertically relative to the side wall, and automatically opens instantly without the operator's manual push. When the door is closed, the wedge block on the machine tool door passes through the hole on the side panel of the door opening and abuts against the wedge block of the rack. The rack moves backward under the thrust, driving the gear to overcome the spring torsion and rotate. The wedge block is provided with parallel sections and wedge sections. When the machine tool door is fully closed, the end of the rack abuts against the parallel section of the wedge block, thus avoiding the rack abutting against the wedge section of the wedge block, thereby generating a thrust in the X-axis direction on the machine tool door. Finally, when the machine tool door is fully closed, the armrest is rotated 90° and stored in the groove, and the armrest and the machine tool door are linked to realize automatic deployment and folding of the armrest, thereby improving convenience.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1, as Figure 1 As shown, a built-in handrail for a processing machine tool is installed on the side wall 8 next to the door opening in the machine tool, and includes a cross bar 2 for connection and a longitudinal bar 1 for the operator to hold. The cross bars 2 are provided with four, and the four cross bars 2 and the longitudinal bars 1 are connected as a whole. The cross bars 2 are connected to the side wall 8. The longitudinal bars 1 and the cross bars 2 are formed by bending and welding round tubes, and are welded to the side wall 8 of the machine tool as a whole, and are painted for corrosion protection together with the side wall 8 during production. Or a connecting block is installed at the end of the cross bar 2, the handrail is separately anti-corrosive, and then locked on the side wall 8 of the machine tool by bolts. With this arrangement, the machine tool operator can hold the longitudinal bar 1 with one hand when loading and unloading, and then lean over to enter the machine tool, so that there is a better fulcrum, and the other hand can be used to load and unload materials. This improves the safety performance and convenience of operation for loading and unloading small parts (from a few hundred shells to several kilograms) that are convenient for precision engraving machine processing, and avoids the problem of oily hands touching the sliding door, which will cause oil stains on the door and affect the appearance of the machine tool.

[0026] Embodiment 2, as Figure 2As shown in the figure, the right side is the normal state and the left side is the manually pushed and unfolded state. The difference from the first embodiment is that in this embodiment, the armrest is rotatably connected and provided with a rotating shaft 3. The rotating shaft 3 is fixedly connected to the cross bar 2. The upper and lower ends of the rotating shaft 3 are rotatably connected to the side wall 8 through bearing seats. A limiting mechanism 5 is arranged between the rotating shaft 3 and the side wall 8. The limiting mechanism 5 is a stop block installed on the side wall 8. A short column is connected to the relative position of the rotating shaft 3. When the armrest and the side wall 8 are in a vertical state, the short column abuts against the stop block. Therefore, the limiting mechanism can limit the rotation of the armrest within an angle range of 90° from being perpendicular to the side wall 8 to pointing to the door opening. An elastic member 4 is arranged on the rotating shaft 3. The elastic member is a torsion spring, and the torsion spring can keep the armrest in a state of pointing to the door opening without power.

[0027] Therefore, in this embodiment, generally, the armrest remains in a state of pointing to the door opening, that is, it fits against the side wall 8. When loading and unloading, hold the vertical rod 1 with one hand and rotate it by 90°. Then bend down and enter the door opening. The armrest supports the upper body, and the other hand is used for loading and unloading. After loading and unloading, without the thrust of the hand, the armrest automatically rotates and leans against the side wall under the action of the torsion force of the torsion spring, avoiding problems of occlusion or interference during processing. The torsion spring generally has a preset torsion force of 5-10 N, which is sufficient to drive the rotation of the armrest.

[0028] Embodiment Three, as Figure 3 shown in the figure, where the right side is the normal state and the left side is the manually pushed and unfolded state. The difference from the second embodiment is that a rectangular groove 9 is provided on the side wall 8. The armrest is arranged in the groove 9. When the armrest rotates to be perpendicular to the side wall 8, the cross bar 2 abuts against the side surface of the groove 9, and the side surface of the groove 9 constitutes the limiting mechanism 5. When the armrest rotates to point to the door opening, the cross bar 2 abuts against the bottom surface of the groove 9. The upper and lower ends of the rotating shaft 3 are respectively rotatably connected to the upper and lower surfaces of the groove 9. The rotating shaft 3 can be sleeved in the round holes on the upper and lower two surfaces of the groove 9, and sleeves are provided at the round holes, or it can be rotatably connected by a bearing seat after passing through the round holes.

[0029] This embodiment mainly adds a groove 9 for accommodating the armrest. When not loading and unloading, the armrest automatically fits in the groove 9, making the side wall 8 relatively flat, without protrusions, more beautiful, and safer, and not easily causing interference.

[0030] Embodiment Four, as Figures 4-6As shown, on the basis of the third embodiment, a linkage effect with the door is added, and the torsion direction of the torsion spring is opposite to that of the third embodiment. The torsion spring can keep the rotating shaft 3 in a state of being vertical to the side wall 8 without power. Specifically: a gear 6 is installed on the top of the rotating shaft 3, and a mounting frame is arranged inside the machine tool (the mounting frame is not shown in the figure, and the guide rail is fixed on the mounting frame in the figure). A rack 7 is slidably arranged on the mounting frame through the guide rail and the slider. The rack 7 is arranged horizontally and is parallel to the side wall 8. The rack 7 is meshed with the gear 6. Under the action of the torsion spring, the torsion spring drives the rotating shaft 3 to rotate clockwise, and the gear 6 makes the rack 7 have a tendency to move forward. In this embodiment, there are many parts driven by the torsion spring, and its preload force is adjusted to about 10-20N. A wedge surface is arranged at one end of the rack 7, and a wedge block 12 is fixedly installed at the upper end of the machine tool door 10. An opening 11 for accommodating the wedge block 12 to enter is arranged on the side plate of the door opening, and the wedge block 12 can fit with the wedge surface of the rack 7.

[0031] When the door is open, the torsion spring drives the armrest to open automatically. It is perpendicular to the side wall 8 and opens automatically without the operator's manual push. When the door is closed, the wedge block 12 on the machine tool door 10 passes through the hole 11 on the side panel of the door opening and abuts against the wedge block of the rack 7. The rack 7 moves backward under the thrust, driving the gear 6 to rotate to overcome the spring torsion. The wedge block 12 is provided with parallel sections and wedge sections. When the machine tool door 10 is fully closed, the end of the rack 7 abuts against the parallel section of the wedge block 12, thus avoiding the rack abutting against the wedge section of the wedge block, thereby generating an X-axis thrust on the machine tool door 10. Finally, when the machine tool door 10 is fully closed, the armrest rotates 90° and is stored in the groove 9 without interference. This embodiment links the armrest and the machine tool door 10 to achieve automatic deployment and folding of the armrest, thereby improving convenience.

[0032] In other embodiments, the elastic component 4 may also replace the torsion spring with a spring, one end of the spring is attached to the armrest, and the other end is attached to the side wall 8, which can also achieve the rotation function.

[0033] To sum up, the built-in armrest of the processing machine tool described in the utility model provides the operator with a very convenient fulcrum, which is convenient for loading and unloading materials, avoids the sliding door from being stained with oil, improves the aesthetics, and realizes automatic retraction and extension of the armrest through the rotating structure and the machine tool door linkage structure, avoiding obstruction or interference during processing and improving convenience.

Those skilled in the art should understand that the above embodiments are only for explaining the technical concept and features of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it. However, it cannot be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
