Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hinge installation equipment capable of adjusting a door frame door gap, and in particular relates to a hinge machine capable of pre-adjusting a door frame installation door gap. Background Art
[0002] The hinge machine for doors usually mainly pre-sets the door frame and door panel on the platform, positions the door frame and door panel through corresponding molds or fixtures to simulate the actual installation state, and further punches holes in the door frame and door panel at the positions where the hinges are pre-installed through the three-axis machine tool. The three-axis machine tool will also perform groove processing on the positions where the lock core and lock box are pre-installed in the door panel. After the drilling and groove processing, during the actual installation of the door panel, the lock core and lock box can be installed in the corresponding slot, and the hinge can be installed on the pre-punched hole by screws, thereby facilitating installation.
[0003] Among them, it should be noted that with the gradual increase of composite door panels in the prior art, door panels are usually composed of a door panel body and a strip connected as a whole (welding, integrated matching, etc.), and the door panel body and the strip can be processed separately, wherein the strip is mainly used to install the lock core, lock box and hinge. Therefore, in the process of processing the strip separately, grooving and punching operations can be performed in the strip, which can effectively save production space and facilitate production and processing.
[0004] As we all know, doors can be divided into left-opening doors or right-opening doors according to the position of the door lock, and there will be a lower door gap between the door panel and the floor, and an upper door gap between the door panel and the top door frame to reduce collision interference. In order to reduce the purchase cost of the machine, the hinge machine of the prior art usually sets a fixture on the workbench of the equipment for fixing the fixed door panel and door frame to be processed, and at the same time, an upper limit fixture and a lower limit fixture are respectively set on both sides of the fixture. The upper limit fixture is used to limit the end face of the door frame or door panel so that the end face of the door frame and the end face of the door panel are aligned. The lower limit jig is used to limit the end face of the door frame or door panel so that the lower door gap is formed between the end face of the door frame and the end face of the door panel. Therefore, in the process of production and processing, it is necessary not only to distinguish the upper limit jig and the lower limit jig for processing the door frame and mask to be processed (commonly known as distinguishing the left and right lock clamps), but also when the upper door gap or the lower door gap changes, it is necessary to replace the upper limit jig or the lower limit jig of different sizes, which will reduce the processing versatility and reduce the processing efficiency.

[0029] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" used in this specification are only used to facilitate the description and are not used to limit the scope of the present invention. The changes or adjustments in their relative relationships shall also be regarded as the scope of the present invention without substantially changing the technical content.
[0030] A hinge machine for pre-adjusting the door frame installation door gap, such as Figure 1 and Figure 2 As shown, it includes a working platform 1 and a fixing fixture 2 and a limit adjustment plate 7 installed on the working platform 1, and the limit adjustment plate 7 is located on one side of the fixing fixture 2; the fixing fixture 2 is used to install the corrugated strips and the door frame strips, and the corrugated strips and the door frame strips are both pressed against the side of the limit adjustment plate 7, and the limit adjustment plate 7 is used to adjust the distance between the end face of the door frame strip and the end face of the corrugated strip (the distance is used to simulate the upper door gap or lower door gap generated during actual installation). After the corrugated strips and the door frame strips are positioned and adjusted by the limit adjustment plate 7, the corrugated strips and the door frame strips are also fixed by the fixing fixture 2, so as to facilitate the punching of holes at the positions where the hinges are pre-installed in the door frame strips and the corrugated strips by the three-axis machine tool.
[0031] In this embodiment, there are multiple fixing clamps 2, two limit adjustment plates 7, and a track (not shown) is provided on the working platform 1. Several fixing clamps 2 are slidably mounted on the track. Therefore, the spacing between the two fixing clamps 2 at the end can be adjusted by sliding the fixing clamps 2, so as to adapt to door frames or door panels of different sizes and lengths. The fixing clamps 2 are locked and connected to the working platform 1 by screws to limit the sliding of the fixing clamps 2. The two limit adjustment plates 7 are respectively mounted on the two fixing clamps 2 at the two ends along the length direction of the track. Therefore, in actual use, there is no need to distinguish between the limit adjustment plates 7 on both sides. The gap between the end face of the corrugated strip and the end face of the door frame strip can be adjusted by the single-sided limit adjustment plate 7. The gap can be the adjustment of the upper door gap or the adjustment of the lower door gap. After the adjustment, the corrugated strip and the door frame strip are fixed, and the subsequent punching operation of the hinge pre-installation position can be performed, which has the advantage of simple operation.
[0032] The fixing fixture 2 of this embodiment realizes the function of installing and fixing the corrugated strips and the door frame strips: the fixing fixture 2 has two corrugated strip installation positions 21 and two door frame strip installation positions, the two corrugated strip installation positions 21 are located between the two door frame strip installation positions, and the corrugated strip installation positions 21 and the door frame strip installation positions both extend in the direction toward the limit adjustment plate 7 and pass through the fixing fixture 2. Therefore, by setting two groups of corrugated strip installation positions 21 and door frame strip installation positions, the corrugated strip installation positions 21 are used to install corrugated strips, and the door frame strips are used to install door frame strips, and their fixation can be achieved manually; therefore, the corrugated strip installation positions 21 and the door frame strip installation positions on one side can be used to process the left door panel or the right door panel, while the other side can be used to process the right door panel or the left door panel, thereby achieving the effect of efficient processing.
[0033] In order to achieve the fixing effect on the ribs and door frame strips, the present embodiment adopts the following settings for the fixing fixture 2: the fixing fixture 2 includes a base plate 3, a bidirectional moving member 4, a limiting plate 41 and two linear moving members 6. The base plate 3 is slidably mounted on the slide rail, and the base plate 3 can be mounted on the working platform 1 by screwing. The bidirectional moving member 4 can be a bidirectional air cylinder, a bidirectional hydraulic cylinder or a bidirectional electric cylinder. The bidirectional moving member 4 is mounted on the base plate 3 by screwing. The bidirectional moving member 4 has two moving ends with opposite moving directions. The moving end of the bidirectional moving member 4 is provided with a moving plate 42. The limiting plate 41 is fixedly mounted on the cylinder surface of the bidirectional moving member 4. The rib installation position 21 is formed between the limiting plate 41 and the moving plate 42. The linear moving member 6 can adopt a unidirectional linear cylinder, a hydraulic cylinder or an electric cylinder. The linear moving member 6 is installed on the base plate 3 by screwing. The two linear moving members 6 are located on both sides of the two moving ends of the bidirectional moving member 4. The linear moving member 6 has an extended end. The extended end of the linear moving member 6 is provided with a fixed plate. The fixed plate is opposite to the moving plate 42, and a door frame strip installation position is formed between the fixed plate and the moving plate 42.
[0034] Therefore, when the strip is placed in the strip installation position 21 and needs to be fixed, the bidirectional moving member 4 is started to move the moving plate 42 toward the limiting plate 41, so that the strip is clamped and fixed by the moving plate 42 and the limiting plate 41; similarly, when the door frame strip is placed in the door frame installation position 22 and needs to be fixed, the linear moving member 6 is started to move the top plate toward the moving plate 42, so that the door frame strip is clamped and fixed by the fixing plate and the moving plate 42. It should be noted that the thickness of the moving plate 42 is the outer diameter of the bearing for pre-installing the hinge between the strip and the door frame plate.
[0035] Based on the above introduction about the rib installation position 21, the rib is placed on the top surface of the cylinder on one side of the bidirectional movable member 4, so the rib will be at a certain height position. In order to make the rib and the door frame strip at the same height position, and thus facilitate the subsequent pre-processing of the hinge hole position, the following setting is adopted: the bottom plate 3 is located between the bidirectional movable member 4 and the linear movable member 6, and a pad is arranged, and the end face of the pad away from the bottom plate 3 forms a support surface for the door frame strip.
[0036] Meanwhile, the movable plate 42 and the fixed plate of the present embodiment are both made of plastic or wooden materials. Therefore, when the two-way movable member 4 or the linear movable member 6 is started to clamp and fix the ribbed strips or door frame strips, the movable plate 42 and / or the fixed plate made of plastic or wooden materials can reduce the damage caused by the impact on the ribbed strips and / or door frame strips, thereby achieving a good protective effect.
[0037] The position limiting adjustment plate 7 of this embodiment realizes the function of adjusting the gap between the end face of the corrugated strip and the end face of the door frame strip: the position limiting adjustment plate 7 is directly opposite to the corrugated strip installation position 21 and the door frame strip installation position, and the position limiting adjustment plate 7 is provided with an adjustment hole, which is directly opposite to the door frame strip installation position, and the adjustment hole is connected with an adjustment bolt (not shown in the figure), and the adjustment bolt is located on the outside away from the fixing fixture 2. Thus, the door panel corrugated strip and the door frame strip are respectively installed at the corrugated strip installation position 21 and the door frame strip installation position on one side, and both are against the side of the position limiting adjustment plate 7, and the bidirectional moving member 4 is first started, so that the moving plate 42 and the position limiting plate 41 clamp and fix the corrugated strip, and then the adjusting bolt is adjusted by rotating the adjusting bolt to adjust the abutting position between the end face of the door frame strip and the end of the adjusting bolt, thereby adjusting the distance between the end face of the door panel corrugated strip and the end face of the door frame strip.
[0038] In order to improve the stability of the abutment position between the end face of the door frame strip and the end of the adjusting bolt, a limiting groove 71 is provided on the side of the limit adjustment plate 7 facing the door frame strip installation position, and the limiting groove 71 is directly opposite to the supporting surface of the pad. The limiting groove 71 is provided for the end of the door frame strip to be inserted and positioned. Since the door frame strip of the utility model adopts a hollow special-shaped steel structure, the internal ribs of the end face of the door frame strip can be inserted and adapted to the limiting groove 71, and the internal ribs at the end of the door frame strip can be abutted against the upper inner top surface of the limiting groove 71, thereby achieving the positioning effect; the adjusting hole is provided on the inner wall of the limiting groove 71, so in the process of rotating the adjusting bolt, the end of the adjusting bolt will push against the internal ribs at the end of the door frame strip, thereby achieving the effect of adjusting the abutment position.
[0039] In summary, the utility model sets a fixing fixture 2 and a limit adjustment plate 7 on the working platform 1, wherein the strip installation position 21 and the door frame installation position 22 on the fixing fixture 2 are two symmetrical groups, which are respectively suitable for installing the strips and door frame strips used for processing the left door panel and the right door panel, and by abutting the installed strip ends and the door frame strip ends against the side of the same limit adjustment plate 7, and then adjusting the abutting position between the end face of the door frame strip and the end of the adjusting bolt by cantilevering the adjusting bolt, the function of adjusting the gap between the end face of the strip and the end face of the door frame strip is realized, so that the gap simulates the upper door gap or the lower door gap generated in the actual installation. Compared with the prior art technology that uses the upper limit fixture and the lower limit fixture to position and form the upper door gap and the lower door gap respectively, the utility model uses a single limit adjustment plate 7, which can form the required upper door gap and / or lower door gap by adjustment, and there is no need to distinguish and use them, so it has better versatility, is convenient for simulating the processing effect, and can effectively improve work efficiency.
[0040] The implementation methods of the utility model are not limited to this. According to the above content of the utility model, by using common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the utility model, the utility model can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the utility model.
