Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine guide rail technology, specifically a gantry milling machine guide rail mechanism. Background Technology

[0002] A gantry milling machine is a large milling machine named for its portal frame (gantry frame). It is mainly used for processing large workpieces or mass production. Its working principle is as follows: the worktable can move longitudinally, and the spindle box (with cutting tools) can move laterally and vertically on the gantry frame beam and column to achieve multi-directional processing.

[0003] When a gantry milling machine is machining parts, it generates a large amount of blank debris. When the worktable moves longitudinally, the debris falls and adheres to the outside of the worktable's guide rail. This debris will aggravate the wear between the guide rail slide and the guide rail, affecting the service life of the guide rail. Based on this, a guide rail mechanism for a gantry milling machine is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a guide rail mechanism for a gantry milling machine in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gantry milling machine guide rail mechanism, comprising a guide rail assembly consisting of a linear guide rail and a slide table, wherein the slide table is slidably sleeved on the outside of the linear guide rail, and a debris removal assembly is installed at both ends of the slide table. The debris removal assembly is used to perform a blowing operation to remove debris from the upper surface and sides of the linear guide rail, thereby preventing debris from adhering to and remaining on the upper surface and sides of the linear guide rail.

[0006] The impurity removal assembly includes a blowing unit and a sealing installation unit;

[0007] The blowing unit is used to connect to an external air pump and to guide airflow to blow and remove impurities from the upper surface and both sides of the linear guide rail.

[0008] The sealing installation unit is used to connect and seal the blowing unit and the slide.

[0009] As a further embodiment of this utility model: the blowing unit includes a concave connecting plate, a concave blowing chamber, a concave air chamber, a concave inclined air outlet, and an L-shaped connector;

[0010] The concave spray chamber is fixed to the front end of the concave connecting plate, and the concave connecting plate is fixedly connected to the end face of the slide table by bolts;

[0011] The concave air chamber is formed inside the concave blowing chamber, and the concave inclined air outlet is opened at the front end of the inner wall of the concave air chamber and extends to the front end of the concave blowing chamber.

[0012] The L-shaped connector is fixed to the outside of the concave blow chamber and communicates with the inner cavity of the concave air chamber. The L-shaped connector is connected to an external air pump through a hose.

[0013] The channel, consisting of an L-shaped connector, a concave jet chamber, and a concave air chamber, is used to guide airflow to spray onto the upper surface and both sides of the linear guide rail.

[0014] As a further embodiment of this utility model: three L-shaped connectors are provided on the outside of the concave spray chamber, two of which are symmetrically distributed on the middle of both sides of the concave spray chamber, and the other L-shaped connector is distributed on the middle of the top of the concave spray chamber.

[0015] As a further improvement of this utility model, the vertical section of the concave inclined air outlet is inclined from top to bottom toward the upper surface of the linear guide rail.

[0016] As a further embodiment of this utility model: the sealing installation unit includes a sealing mating groove, a concave sealing element, and a through hole;

[0017] The sealing docking groove is integrally formed at the rear end of the concave connecting plate and the concave blowing chamber, and the sealing docking groove is connected to the inner cavity of the concave air chamber.

[0018] The concave seal is embedded in the inner side of the sealing groove. The through hole passes through the concave connecting plate and the concave seal sequentially from the front end of the concave connecting plate. Both ends of the slide are provided with screw holes corresponding to the through holes. Bolts are used to pass through the concave seal and connect with the screw holes to tighten them, so as to realize the connection and fixation between the concave connecting plate and the slide.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up a debris removal component, during the movement of the slide, the component connects to an external air pump to guide airflow to the upper surface and sides of the quasi-linear guide rail, causing residual debris adhering to the upper surface and sides of the linear guide rail to be blown away. This avoids the situation where the moving slide comes into contact with debris, which would lead to increased wear, and further improves the operational stability and service life of the guide rail assembly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 In this embodiment of the utility model, a gantry milling machine guide rail mechanism includes a guide rail assembly 1 consisting of a linear guide rail 101 and a slide table 102. The slide table 102 is slidably sleeved on the outside of the linear guide rail 101. The two ends of the slide table 102 are equipped with a cleaning component 2. The cleaning component 2 is used to perform a blowing cleaning operation on the upper surface and sides of the linear guide rail 101 to prevent debris from adhering and remaining on the upper surface and sides of the linear guide rail 101.

[0028] The impurity removal component 2 includes a blowing unit and a sealing installation unit;

[0029] The blowing unit is used to connect to an external air pump and to guide airflow to blow and remove impurities from the upper surface and both sides of the linear guide rail 101.

[0030] The sealing mounting unit is used to connect and seal the blowing unit and the slide table 102;

[0031] The blowing unit includes a concave connecting plate 201, a concave blowing chamber 202, a concave air chamber 203, a concave inclined air outlet 204, and an L-shaped connector 205;

[0032] The concave spray chamber 202 is fixed to the front end of the concave connecting plate 201, and the concave connecting plate 201 is fixedly connected to the end face of the slide table 102 by bolts;

[0033] The concave air chamber 203 is formed inside the concave blowing chamber 202, and the concave inclined air outlet 204 is opened at the front end of the inner wall of the concave air chamber 203 and extends to the front end of the concave blowing chamber 202.

[0034] The L-shaped connector 205 is fixed to the outside of the concave jet chamber 202 and communicates with the inner cavity of the concave air chamber 203. The L-shaped connector 205 is connected to an external air pump through a hose.

[0035] The channel formed by the L-shaped connector 205, the concave jet chamber 202, and the concave air chamber 203 is used to guide airflow to spray onto the upper surface and both sides of the linear guide rail 101.

[0036] The sealing installation unit includes a sealing mating groove 206, a concave seal 207, and a through hole 208;

[0037] The sealing docking groove 206 is integrally formed at the rear end of the concave connecting plate 201 and the concave blowing chamber 202, and the sealing docking groove 206 is connected to the inner cavity of the concave air chamber 203.

[0038] The concave seal 207 is embedded in the inner side of the sealing groove 206. The through hole 208 passes through the concave connecting plate 201 and the concave seal 207 sequentially from the front end of the concave connecting plate 201. Both ends of the slide table 102 are provided with screw holes 103 corresponding to the through holes 208. The concave seal 207 is threaded through the bolt and screwed into the screw holes 103 to achieve the connection and fixation between the concave connecting plate 201 and the slide table 102.

[0039] In this embodiment, the guide rail mechanism of this gantry milling machine is used as follows:

[0040] The impurity removal components 2 are installed at both ends of the slide table 102. First, the concave seal 207 is embedded inside the sealing groove 206, and then it is attached to the end face of the slide table 102 as a whole. (It should be noted that the thickness of the concave seal 207 is slightly thicker than the depth of the sealing groove 206. The concave seal 207 is initially attached to the end face of the slide table 102.) Then, the bolts are threaded through the through hole 208 and screwed into the screw hole 103. The bolts press against the concave connecting plate 201, and the concave seal 207 deforms under this extrusion pressure. Finally, the concave seal 207 is flush with the end face of the concave connecting plate 201 and tightly attached to the end face of the slide table 102. At the same time, the concave seal 207 is tightly attached to the inner wall of the sealing groove 206, thereby achieving the sealing of the concave air chamber 203 and completing the connection and fixation between the concave connecting plate 201 and the slide table 102.

[0041] Then, the L-shaped connector 205 is connected to the external air pump via a hose. When the worktable of the gantry milling machine moves, the slide 102 moves synchronously along the linear guide 101. At this time, the external air pump is started synchronously and the connecting pipe between the air pump 101 and the L-shaped connector 205 is connected, so that high-pressure air is delivered to the L-shaped connector 205 and enters the concave air chamber 203. Then it is sprayed out through the concave inclined air nozzle 204. The sprayed air is aimed at the upper surface and sides of the linear guide 101, so that the debris adhering to the upper surface and sides of the linear guide 101 is blown away, keeping the upper surface and sides of the linear guide 101 in a good clean state. This avoids the situation where the moving slide 102 comes into contact with debris, which would lead to increased wear. This further improves the operational stability and service life of the guide rail assembly 1.

[0042] Please refer to this carefully. Figures 1-4 Three L-shaped connectors 205 are provided on the outside of the concave spray chamber 202. Two L-shaped connectors 205 are symmetrically distributed on the middle of both sides of the concave spray chamber 202, and the other L-shaped connector 205 is distributed on the middle of the top of the concave spray chamber 202.

[0043] The vertical section of the concave inclined air outlet 204 is inclined from top to bottom toward the upper surface of the linear guide rail 101.

[0044] In this embodiment: the structure of three L-shaped connectors 205 allows high-pressure airflow to be connected to the top horizontal part and the two vertical parts on both sides of the concave blowing chamber 202, so that the high-pressure airflow can fill the concave inclined blowing port 204, ensuring the "concave" blowing trajectory, and thus realizing the comprehensive blowing and impurity removal of the upper surface and sides of the linear guide rail 101.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
