Description

Technical Field

[0001] The embodiments of this utility model relate to the technical field of dual-station tooling for horizontal machining centers, specifically, to a dual-station tooling for horizontal machining centers. Background Technology

[0002] In the field of glass mold processing, glass molds, as key tooling for forming glass products, directly affect the quality of the final product due to their surface finish, dimensional accuracy, and structural complexity. Therefore, during processing, tooling is needed to firmly clamp the mold to ensure stability and positioning accuracy. Especially for mass production glass mold processing scenarios, dual-station tooling has become the mainstream choice because it enables parallel operation of loading / unloading and processing, significantly improving production efficiency.

[0003] Traditional dual-station clamping fixtures for horizontal machining centers primarily employ a symmetrically arranged double-jaw block structure. Their core function is to clamp and release the glass mold through the lifting and moving of the jaw blocks. These fixtures typically use a hydraulic or pneumatic drive system to control the vertical movement of the jaw blocks, utilizing the friction between the jaw blocks and the mold contact surface, as well as mechanical limiting action, to fix the glass mold in a preset position on the machining platform. During machining, the main structure of the fixture is rigidly connected to the machining center's worktable, and the clamped mold remains in a fixed position. Cutting operations are completed solely through the multi-axis linkage of the machining center's spindle.

[0004] However, the structural limitations of traditional tooling result in significant shortcomings in practical applications. Since the two clamping blocks can only move in the lifting direction, the degrees of freedom during machining are limited. For complex glass molds, such as those with deep cavities, oblique holes, or irregular curved surfaces, the fixed clamping position can cause interference between the machining tool and certain areas of the mold, or prevent the achievement of the optimal cutting angle. To address this issue, some production scenarios necessitate the additional configuration of high-degree-of-freedom robotic arms to assist in adjusting the mold's posture. This not only significantly increases equipment procurement costs but also raises system complexity due to the need for coordinated control between the robotic arm and the machining center. Furthermore, it increases potential points of equipment failure, complicates subsequent maintenance, and impacts production continuity and economic efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a dual-station tooling for a horizontal machining center, which solves the technical problems of existing technology where the two clamps can only move in the lifting direction, resulting in low degree of freedom in the machining process, and the high procurement cost and difficult maintenance of high-degree-of-freedom robotic arms, which affect the continuity and economy of production.

[0006] According to one aspect, at least one embodiment of the present invention provides a dual-station tooling for a horizontal machining center, comprising:

[0007] For example, in at least one embodiment of the present invention, a dual-station tooling for a horizontal machining center further includes: a base; A clamping assembly for clamping a mold, the clamping assembly comprising: An upper support platform and a lower support platform, wherein the upper support platform and / or the lower support platform are raised and lowered on the base platform, and the lower support platform and the upper support platform are arranged at intervals; An upper turntable and a lower turntable, wherein the upper turntable is rotatably mounted on the upper support platform and the lower turntable is rotatably mounted on the lower support platform; An upper clamping block and a lower clamping block are provided.

[0011] For example, in a dual-station tooling for a horizontal machining center provided in at least one embodiment of the present invention, the upper clamping block is movably disposed on the upper turntable in a horizontal direction; The lower clamp block is horizontally movable on the lower turntable, and the upper clamp block and the lower clamp block can move synchronously to drive the mold to move horizontally.

[0012] For example, in a dual-station tooling for a horizontal machining center provided in at least one embodiment of this utility model, the upper rotary table has a slide groove, the upper clamp block has a slider that slides in cooperation with the slide groove, and further includes: A lead screw, which is rotatably disposed within the groove and threadedly connected to the slider; An electric motor is mounted on the upper turntable and is used to drive the lead screw to rotate.

[0014] For example, in a dual-station tooling for a horizontal machining center provided in at least one embodiment of the present invention, a linear drive is further included. The linear drive is disposed on the base and is used to drive the upper support platform to rise and fall. The drive end of the linear drive is located on the side of the motor near the base.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 As shown, this utility model illustrates a dual-station tooling for a horizontal machining center. This tooling is mainly used to clamp glass mold blanks and process the blanks using a machine tool. In this solution, the dual-station tooling for the horizontal machining center includes a base 100, which is the basic support structure of the entire tooling and provides an installation platform for the clamping assembly 200.

[0028] The clamping assembly 200 is used to clamp a glass mold. This assembly includes an upper support platform 201 and a lower support platform 202, an upper turntable 203 and a lower turntable 204, an upper clamping block 205 and a lower clamping block 206. The upper support platform 201 and the upper turntable 203, and the lower support platform 202 and the lower turntable 204, respectively form two sets of connecting structures. The upper turntable 203 can rotate on the upper support platform 201, and the lower turntable 204 can rotate on the lower support platform 202. The rotation of the turntables provides rotational freedom for the clamping blocks and the clamped mold.

[0029] The upper turntable 203 is connected to the upper clamping block 205, and the lower turntable 204 is connected to the lower clamping block 206. The upper clamping block 205 is mounted on the upper turntable 203, and the lower clamping block 206 is mounted on the lower turntable 204. The rotation of the turntables causes the clamping blocks and the mold to rotate together, and the clamping blocks are directly used to clamp and fix the mold. The upper clamping block 205 and the lower clamping block 206 work together to complete the clamping and releasing actions of the mold.

[0030] The lifting and lowering of the upper support platform 201 and the lower support platform 202 on the base 100 can be achieved by a linear drive component 400 (such as a hydraulic, pneumatic, or electric actuator, etc., which is not limited here). In some examples, either the upper support platform 201 or the lower support platform 202 can be lifted or lowered to achieve the clamping of the glass mold. In this solution, only the upper support platform 201 is lifted, while the lower support platform 202 is fixed. The reason is that the lower support platform 202 needs to bear the weight of the glass mold and other forces, and it is necessary to maintain the overall structural strength and stability.

[0031] Specifically, the mold is first placed on the lower clamp block 206, and the upper support platform 201 is lowered, causing the upper clamp block 205 to approach and abut against the upper end of the mold until the upper clamp block 205 and the lower clamp block 206 together clamp the mold. Reversing the operation is performed to release the mold. This lifting action can accommodate molds of different heights, increasing the tooling's adaptability to mold height.

[0032] The rotation of the upper rotary table 203 and the lower rotary table 204 on the upper support platform 201 and the lower support platform 202, respectively, is powered by the drive motor 302. By controlling the rotation angle of the upper rotary table 203 and the lower rotary table 204, the angles of the upper clamping block 205 and the lower clamping block 206, as well as the clamped mold, can be adjusted, providing more cutting angle options for machining molds with complex shapes and helping to avoid interference between the machining tool and parts of the mold.

[0033] In some examples, the upper turntable 203 and the lower turntable 204 are spaced apart from the base 100, providing necessary space for their rotation. The base 100, as the fundamental support structure of the entire fixture, does not directly participate in the rotation of the upper and lower turntables 203 and 204, but it ensures their installation and stable rotation. The axes of rotation of the upper and lower turntables 203 and 204 are perpendicular to the horizontal plane, ensuring that they can rotate around their axes in the horizontal plane. Furthermore, the spaced design with the base 100 prevents interference between the upper and lower turntables 203 and 204 and the base 100 during rotation.

[0034] In practical work, when the mold's posture needs to be adjusted, the upper support platform 201 can first be raised and lowered according to the mold's height to adjust the mold to a suitable height position. Subsequently, the upper turntable 203 and the lower turntable 204 rotate in the horizontal plane driven by the drive motor 302, driving the upper clamp block 205, the lower clamp block 206, and the mold to rotate to the required angle. This allows the tooling to flexibly adjust the mold's posture to adapt to the processing requirements of glass molds of different shapes, avoid interference between the processing tool and the mold, and improve processing accuracy and efficiency.

[0035] In some examples, the upper turntable 203 provides a horizontal moving platform for the upper clamp block 205. The upper turntable 203 is provided with a slide groove 207, and the upper clamp block 205 slides along the slide groove 207 via a slider 208, achieving horizontal movement. A lead screw 301 is rotatably disposed within the slide groove 207 and threadedly connected to the slider 208. A motor is mounted on the upper turntable 203, driving the lead screw 301 to rotate, thus moving the slider 208 and the upper clamp block 205 horizontally along the slide groove 207. Similar to the relationship between the upper turntable 203 and the upper clamp block 205, the lower turntable 204 also has a slide groove 207, and the lower clamp block 206 slides along the slide groove 207 via the slider 208. A lead screw 301 is also rotatably disposed within the slide groove 207 of the lower turntable 204. The upper clamp block 205 and the lower clamp block 206 together clamp the mold and can move synchronously, driving the mold to move horizontally.

[0036] In some examples, the linear drive 400 is mounted on the base 100, with its drive end connected to the upper support platform 201, responsible for driving the upper support platform 201 to rise and fall. Because the drive end is located on the side of the motor closer to the base 100, and the slide 207 is located on the side wall of the base 100, the drive end's proximity to the side wall makes the driving process more stable, enhancing the stability and reliability of the upper support platform 201 during rise and fall. This structural arrangement relies heavily on the support of the base 100, which provides the mounting foundation and positioning reference for the linear drive 400 and the upper support platform 201.

[0037] Friction surfaces 500 are respectively provided on the lower end face of the upper clamping block 205 and the upper end face of the lower clamping block 206. When the upper clamping block 205 and the lower clamping block 206 approach and clamp the mold, the friction surfaces 500 on the lower end face of the upper clamping block 205 and the upper end face of the lower clamping block 206 are in close contact with the mold surface. According to the principle of friction, the greater the contact pressure, the greater the friction, thereby firmly clamping the mold and preventing the mold from sliding or displacing due to external forces such as cutting forces during processing.

[0038] In some examples, two sets of clamping assemblies 200 are respectively disposed on both sides of the base 100, which provides stable support and mounting positions for the two sets of clamping assemblies 200. The two sets of clamping assemblies 200 are relatively independent but share the basic support of the base 100. They form an integrated dual-station tooling structure through their connection with the base 100.

[0039] The two clamping components 200 are functionally independent, each capable of clamping, rotating, lifting, and horizontally moving the molds placed at its respective workstation. However, they are also within the same tooling system, enabling parallel operation of loading / unloading and processing within the overall machining flow, thus improving production efficiency.

[0040] In the mass production of glass molds, one set of clamping components 200 can be used to process the molds, while the other set can simultaneously perform loading and unloading operations. For example, when the clamping blocks in one set of clamping components 200 clamp the mold, the mold angle is adjusted by rotating the turntable, the mold height is adjusted by raising and lowering the support platform, and the mold position is finely adjusted by moving the clamping blocks horizontally, and then the machining center processes the mold. At the same time, the operator can place a new mold to be processed or remove a completed mold at the other set of clamping components 200, realizing parallel operation of processing and loading / unloading, which greatly improves production efficiency. Supported by the base 100, the two sets of clamping components 200 independently complete the operation of the molds, together forming a highly efficient dual-station machining system.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
