Description

Technical Field

[0001] This application belongs to the technical field of mechanical processing equipment structure, specifically relating to a horizontal machining center column with counterweight function. Background Technology

[0002] Currently, with the continuous advancement of machining technology, machined parts are becoming increasingly complex and larger in size. While some traditional machining equipment possesses good machining accuracy, its operating range and load-bearing capacity are limited, making it difficult to process large and heavy workpieces. Some equipment can process large and heavy workpieces, but the machining accuracy is generally low, hindering precision machining. Therefore, traditional machining equipment struggles to meet the machining needs of certain fields. Many equipment manufacturers are developing machining equipment with high precision suitable for large workpieces. As the most important moving component of a machining center, the performance of the machining center column is a crucial factor determining machining accuracy.

[0003] The column of a horizontal machining center often needs to be equipped with a heavy headstock. The up and down movement of the headstock will put great pressure on the connection points of the driving components, making the relevant components prone to damage. Counterweight components are required. However, most existing counterweight components use a combination structure of counterweight blocks and pulleys to achieve the counterweight function. This can easily cause the chain to swing and deviate during use, affecting the counterweight function. There is an urgent need for a solution that can solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a horizontal machining center column with counterweight function to address the shortcomings of the existing technology. In practical applications, the counterweight function is achieved through a counterweight cylinder, a second guide rail, a movable pulley assembly, and a fixed pulley assembly, thereby increasing stability.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A horizontal machining center column with counterweight function includes a fixed column, a drive motor mounted on the top of the fixed column, a user side of the fixed column, and a headstock housing driven by the drive motor mounted on the user side. The column also includes:

[0007] A counterweight cylinder is fixedly installed on the counterweight side of the fixed column relative to the use side. The counterweight cylinder includes a cylinder body and a movable rod installed on the drive end of the cylinder body. A movable pulley assembly is provided at the top of the movable rod.

[0008] A fixed pulley assembly is disposed on the top of the fixed column;

[0009] A chain, the initial end of which is connected to the headstock, and the terminal end of which passes around the fixed pulley assembly and the movable pulley assembly and is connected to the fixed pulley assembly;

[0010] The counterweight side is equipped with a first guide rail, the top of the moving rod is fitted with a moving component, and the moving component is equipped with a first slider that matches the first guide rail.

[0011] As an improvement to the horizontal machining center column with counterweight function described in this application, the movable pulley assembly includes a first bracket and a movable pulley fixed to the first bracket by a first bearing, and the chain passes around the movable pulley.

[0012] As an improvement to the horizontal machining center column with counterweight function described in this application, the fixed pulley assembly includes a second bracket and a fixed pulley fixed to the second bracket by a second bearing, the chain passes around the fixed pulley, and the termination end is fixed to the side of the second bracket near the movable pulley.

[0013] As an improvement to the horizontal machining center column with counterweight function described in this application, the cylinder body is fixedly installed on the counterweight side by a third bracket.

[0014] As an improvement to the horizontal machining center column with counterweight function described in this application, the drive end of the drive motor is provided with a lead screw, and the headstock is sleeved on the lead screw.

[0015] As an improvement to the horizontal machining center column with counterweight function described in this application, a second guide rail is installed on the use side, and a second slider matching the second guide rail is provided on the side of the headstock near the use side.

[0016] The beneficial effects of this application are as follows: the second guide rail in this application can guide the movement of the movable pulley assembly, and the fixed pulley assembly is fixedly installed on the top of the fixed column. The two work together to reduce the swaying amplitude of the chain during the movement of the counterweight cylinder and the head box, thereby increasing the overall stability and ensuring that the counterweight function is better realized.

[0033] The following is in conjunction with the appendix Figures 1-3 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

[0034] Implementation

[0035] A horizontal machining center column with counterweight function includes a fixed column 1 and a chain 7. The top of the fixed column 1 is equipped with a drive motor 2 and a fixed pulley assembly 6. The fixed column 1 includes a user side 11 and a counterweight side 12. The user side 11 is equipped with a headstock box 3. The drive end of the drive motor 2 is provided with a lead screw 8, and the headstock box 3 is sleeved on the lead screw 8. The counterweight side 12 is equipped with a counterweight cylinder 4. The counterweight cylinder 4 includes a cylinder body 41 and a moving rod 42 installed on the drive end of the cylinder body 41. The top of the moving rod 42 is provided with a movable pulley assembly 5. The initial end of the chain 7 is connected to the headstock box 3, and the terminal end of the chain 7 passes around the fixed pulley assembly 6 and the movable pulley assembly 5 and is connected to the fixed pulley assembly 6. The counterweight side 12 is equipped with a first guide rail 121. The top of the moving rod 42 is sleeved with a moving part 421, and the moving part 421 is equipped with a first slider 422 that matches the first guide rail 121.

[0036] In practical applications, the drive motor 2 drives the head box 3 to move up and down via the lead screw 8. The head box 3 is connected to external components. Due to the large weight of the head box 3, pressure will be concentrated at the connection point with the lead screw 8 during movement, requiring a counterweight device. In this embodiment, a counterweight cylinder 4, a movable pulley assembly 5, and a fixed pulley assembly 6 are used in combination to achieve the counterweight function, avoiding the situation where pressure concentration causes the components to malfunction or be damaged. The counterweight cylinder 4 is a cylinder or other components with the same function, used to provide the power required to balance the head box 3. The movable pulley assembly 5 is used to reduce the stroke required for the counterweight cylinder 4 to move. The fixed pulley assembly 6 is used to change the direction of the force. At the same time, the fixed pulley assembly 6 is fixed to the top of the fixed column, and the first guide rail 121 plays a fixed guiding role in the up and down movement of the movable pulley assembly 5 driven by the counterweight cylinder 4. The two work together to minimize the swaying amplitude of the chain 7 during use, increasing the service life of the chain 7 and increasing the overall stability, thus better ensuring the realization of the counterweight function.

[0037] Specifically, the movable pulley assembly 5 includes a first bracket 51 and a movable pulley 53 fixed to the first bracket 51 via a first bearing 52, with a chain 7 passing over the movable pulley 53; the fixed pulley assembly 6 includes a second bracket 61 and a fixed pulley 63 fixed to the second bracket 61 via a second bearing 62, with a chain 7 passing over the fixed pulley 63, and the end of the chain 7 being fixed to the side of the second bracket 61 near the movable pulley 53.

[0038] In this embodiment, the first bearing 52 and the second bearing 62 are ball bearings, which can reduce friction and facilitate installation; the second bracket 61 is installed at an angle relative to the top surface of the fixed column 1, forming an angle with its edge, which can reserve space for the use of other components and avoid collisions during use due to overly tight installation of components.

[0039] Specifically, the cylinder body 41 is fixedly installed on the counterweight side 12 via the third bracket 411, and the second guide rail 111 is installed on the use side 11. The head box 3 is provided with a second slider 31 that matches the second guide rail 111 on the side close to the use side 11. The fixed use of the cylinder body 41 and the fixed guiding effect of the second guide rail 111 on the movement of the head box 3 further increase the overall stability.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
