Description

Technical Field

[0001] This invention relates to the field of machine tool processing equipment technology, and more specifically, to a double tool holder mounting device. Background Technology

[0002] In modern manufacturing, multi-spindle machine tools are increasingly widely used in fields such as impeller machining due to their high-efficiency machining capabilities. Their structure, where multiple spindles share a single Z-axis, reduces the weight of the Z-axis, thereby improving machining efficiency and lowering machine tool manufacturing costs, making it a key choice in the industry.

[0003] However, this type of structure places special requirements on tool installation, namely, the tool lengths on multiple spindles must be consistent, otherwise it will directly affect the machining accuracy and quality. This issue has become a key factor restricting its performance.

[0004] Currently, heat-shrink tool holders are widely used for tool mounting due to their high clamping accuracy, and they are usually used in conjunction with a tool warming machine to complete the tool mounting operation. However, existing technology has significant limitations: the combination of the tool warming machine and the heat-shrink tool holder can only clamp one tool holder at a time, and it lacks a synchronous control design, making it impossible to ensure that the lengths of multiple tool holders are consistent after mounting. This single-tool mounting mode is difficult to adapt to the strict requirements for tool length uniformity in multi-spindle machine tools (especially multi-spindle machine tools that share a Z-axis), seriously affecting the machining efficiency of multi-spindle machine tools. Summary of the Invention

[0005] The present invention provides a dual-tool holder loading device to solve the problem that existing combinations of tool warming machines and heat-shrink tool holders can only clamp one tool holder at a time and lack synchronous control design, making it impossible to ensure the consistency of tool length after multiple tool holders are loaded. This single-tool loading mode is difficult to adapt to the strict requirements for tool length uniformity in multi-spindle machine tools (especially multi-spindle machine tools sharing a Z-axis), seriously affecting the machining efficiency of multi-spindle machine tools.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-handle tool mounting device, comprising: The handle and the knife, with the knife fitting the handle; The knife heating machine includes a base with two placement seats on it. A vertically mounted drive component is mounted on the base. A mounting plate is mounted on the movable end of the drive component. Two heating components are mounted on the mounting plate and are adapted to the placement seats. The tool mounting mechanism includes two slide rails, both of which are horizontally mounted in front of the mounting plate. A bracket is mounted on the slide rail, and a fixing component is mounted on the bracket. The fixing component includes two fixing frames for fixing the tool. Vertically mounted guide rails are mounted at both ends of the bracket, and an adjustment mechanism is mounted on the guide rail. The adjustment mechanism includes a horizontally mounted connecting plate, and pressure plates are mounted at both ends of the connecting plate. The pressure plates are slidably mounted on the guide rail.

[0007] In a preferred embodiment, the fixed frame is provided with two sets of elastic clips 1 and two sets of elastic clips 2. The two clamping units 1 in each set of elastic clips 1 are arranged symmetrically, and the two clamping units 2 in each set of elastic clips 2 are arranged symmetrically. The elastic clips 1 and elastic clips 2 are staggered and perpendicular to each other.

[0008] In a preferred embodiment, the mounting plate reciprocates vertically along the movable end of the drive assembly.

[0009] In a preferred embodiment, both heating components are horizontally arranged, and each heating component is concentrically arranged with its corresponding placement seat, and the two pressure plates are concentrically arranged with their corresponding fixing frames.

The two limit plates are adapted to the corresponding slide rails, and the minimum distance between the two guide rails is greater than the maximum distance between the two heating components on opposite sides.

[0011] In a preferred embodiment, a frame is provided at the middle position of the bracket, and a vertically mounted drive component two is provided on the frame. The connecting plate is fixedly connected to the output end of the drive component two.

[0012] In a preferred embodiment, sliders are provided on the sides of the two pressure plates that are far apart from each other, and the two sliders are respectively adapted to the corresponding guide rails.

[0013] In a preferred embodiment, the heating assembly is provided with a cooling mechanism, which includes two annular tubes, each with an air inlet. The bottom of the annular tubes is arrayed with a plurality of jet pipes, all of which face the center of the heating assembly.

[0015] In a preferred embodiment, the base is provided with a display screen and a control switch.

[0016] The beneficial effects of this invention are as follows: 1. The present invention provides a tool heating machine with two placement seats and two heating components corresponding to the placement seats, and two pressure plates on the same horizontal plane, so that two tools can be installed onto the corresponding tool holders simultaneously.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] In the prior art, when installing the cutting tool 5 on the tool holder 4, a clip is first taken out and installed on the cutting tool 5. Then, the distance from the bottom of the clip to the top of the cutting tool 5 is measured, which is the tool mounting length of the cutting tool 5 on the tool holder 4. Each time a cutting tool is installed, a measuring tool is needed to measure it. Different specifications of cutting tools require the use of corresponding specifications of clips for assembly. The tool mounting length of the cutting tool 5 is generally assumed to be the distance from the top plane of the tool holder 4 to the top of the cutting tool 5. In actual installation, the bottom of the clip will fit against the top of the tool holder 4. The fixing component 25 in this invention functions similarly to a clip.

[0021] Example 1 This embodiment proposes a dual-tool holder loading device to address the problem in existing technologies where the combination of a tool burner and a heat-shrink tool holder can only clamp one tool holder at a time, and lacks synchronous control design, making it impossible to ensure consistent tool lengths after loading multiple tool holders. This single-tool loading mode is difficult to adapt to the strict requirements for tool length uniformity in multi-spindle machine tools, especially those sharing a Z-axis, severely affecting the machining efficiency of multi-spindle machine tools. For reference Figure 1 and Figure 2 The structure shown is as follows: This dual-handle tool loading device includes: The handle 4 and the cutting tool 5 are adapted to the handle 4; It should be noted that the tool holder 4 is a heat-shrink tool holder, which has the characteristic of increasing inner diameter after heating. The tool holder 4 can be replaced according to the actual size and specifications of the tool 5. This is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0022] The equipment also includes a knife-burning machine 1, which can be referenced in general. Figure 3 and Figure 4 The structure shown includes a base 11, two placement seats 12 on the base 11, a vertically mounted drive assembly 13 on the base 11, a mounting plate 14 on the movable end of the drive assembly 13, and two heating assemblies 15 on the mounting plate 14, which are adapted to the placement seats 12. Cooperate Figure 5 and Figure 6As shown in the structure, it should be noted that the mounting end of the tool holder 4 is of a universal size, and the mounting base 12 can mount various specifications of tool holders 4. This is a mature technology well-known to those skilled in the art, and will not be described in detail in this embodiment. Specifically, it can be determined by... Figure 7 As shown in the structure, the drive component 13 is a linear motor used to drive the mounting plate 14 to move, and the heating component 15 is an induction coil that uses the principle of electromagnetic induction to generate eddy current heating in the tool 5 itself. This is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0023] For details on the tool loading mechanism 2, please refer to [the relevant documentation / reference]. Figure 8 and Figure 9 The structure shown includes a tool mounting mechanism 2 comprising two slide rails 21, both horizontally mounted in front of the mounting plate 14. A bracket 22 is mounted on each slide rail 21, and a fixing component 25 is mounted on each bracket 22. The fixing component 25 includes two fixing frames 251 for fixing the tool 5. Vertically mounted guide rails 23 are mounted at both ends of the bracket 22, and an adjustment mechanism 26 is mounted on each guide rail 23. At this time, refer to... Figure 10 As shown in the structure, the adjustment mechanism 26 includes a horizontally mounted connecting plate 262, and pressure plates 263 are provided at both ends of the connecting plate 262. The pressure plates 263 are slidably mounted on the guide rail 23.

[0024] It should be noted that a magnetic block is provided at the rear end of the slide rail 21, and the side of the bracket 22 near the magnetic block is made of magnetic metal. When the bracket 22 and the magnetic block are stably attached, the two fixing frames 251 are respectively in the same position as the corresponding knife handle 4. The guide rail 23 is used to limit the reciprocating movement of the pressure plate 263 in the vertical direction.

[0025] In this embodiment, the specific implementation scenario is as follows: First, take two knives 5 of the same specification, then take two knife handles 4 that are compatible with the specifications of the knives 5 and fix them in the placement base 12 respectively. Next, insert the two knives 5 into the fixing frame 251 for initial fixation. In the initial state, the pressure plate 263 is in a high position to reserve enough space for the installation of the knives 5, and the bracket 22 is in the foremost position on the slide rail 21 to avoid the heating component 15 from obstructing the installation of the knives 5. When the knives 5 are initially fixed... Then, drive the two pressure plates 263 to move down synchronously. Then, push the two tools 5 down to the preset position according to the preset tool loading length. At this time, the downward movement of the pressure plates 263 can be stopped. Then heat the tool holder 4 to make the inner diameter of the tool holder 4 larger. At this time, the tool 5 can be loaded into the tool holder 4. Then, the cooling mechanism 3 cools the tool holder 4, thereby shrinking the inner diameter of the tool holder 4, so that the tool 5 can be firmly installed in the tool holder 4. At this time, the tool holder 4 and the tool 5 can be removed together and installed on the machine tool for use.

[0026] The fixed frame 251 is provided with two sets of elastic clamps 1 252 and two sets of elastic clamps 253. The two clamping units 1 in each set of elastic clamps 1 252 are symmetrically arranged, and the two clamping units 2 in each set of elastic clamps 253 are symmetrically arranged. The elastic clamps 1 252 and elastic clamps 253 are staggered and perpendicular to each other.

[0027] It should be noted that the instructions are attached. Figure 9 Both clamping unit one and clamping unit two use the elastic force of springs to clamp the tool 5. The tool 5 is not fixed in place, so that the pressure plate 263 can push the tool 5 to move. The staggered arrangement of elastic clamp one 252 and elastic clamp two 253 can clamp the tool 5 from four directions to ensure the stability of the tool 5 and keep it in a vertical position.

[0028] Mounting plate 14 moves back and forth vertically along the movable end of drive assembly 13.

[0029] It should be noted that the mounting plate 14 is provided with multiple mounting holes to facilitate the installation of other accessories on the device.

[0030] Both heating components 15 are horizontally arranged, and both heating components 15 are concentrically arranged with their corresponding placement seats 12. The two pressure plates 263 are concentrically arranged with their corresponding fixing frames 251.

[0031] It should be noted that the heating power and time of the heating component 15 can be controlled by a dedicated control module (not shown in the attached figure), such as a PLC, which is a mature technology well known to those skilled in the art and will not be described in detail in this embodiment.

[0032] Two slide rails 21 are located at both ends of the mounting plate 14, and limit plates are provided at both ends of the bracket 22. The two limit plates are adapted to the corresponding slide rails 21. The minimum distance between the two guide rails 23 is greater than the maximum distance between the two heating components 15 on the opposite sides.

[0033] It should be noted that the minimum distance between the two guide rails 23 is greater than the maximum distance between the two heating components 15 on their opposite sides, which can prevent the guide rails 23 from colliding with the heating components 15 when they move back and forth, resulting in better performance. Furthermore, the guide rail 23 is marked with scale lines (not shown in the attached figure) to facilitate observation by the staff. In this invention, the distance between the bottom of the pressure plate 263 and the top plane of the tool holder 4 is defined as the tool loading length of the tool 5.

[0034] A frame 24 is provided in the middle of the bracket 22, and a vertically mounted drive component 261 is provided on the frame 24. The connecting plate 262 is fixedly connected to the output end of the drive component 261.

[0035] It should be noted that the drive component 261 is an electric actuator, which is used to provide power for the up and down movement of the pressure plate 263.

[0036] Each of the two pressure plates 263 has a slider 264 on the side that is far apart from each other, and the two sliders 264 are respectively adapted to the corresponding guide rails 23.

[0037] It should be noted that the slider 264 is slidably connected to the guide rail 23, which is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0038] The heating assembly 15 is provided with a cooling mechanism 3, which includes two annular pipes 31. The annular pipes 31 are provided with air inlets 32. Several jet pipes 33 are arranged in an array at the bottom of the annular pipes 31, and the several jet pipes 33 are all facing the middle position of the heating assembly 15.

[0039] It should be noted that the air inlet 32 ​​can be connected to an external air supply device, not shown in the attached drawing, such as an air pump. When the air supply device is started, it can blow out cooling air evenly from multiple directions through several jet pipes 33, so that the tool holder 4 can be cooled down quickly, thereby improving the tool loading efficiency.

[0040] Reference Figure 11 As shown in the structure, the bottom of the annular tube 31 is symmetrically provided with insert rods 34, and the top of the heating assembly 15 is provided with slots, with the insert rods 34 fitting into the slots.

[0041] It should be noted that the cooling mechanism 3 and the heating component 15 can be quickly assembled by using the insertion rod 34 with the slot, so as to facilitate the assembly of the device.

[0042] The base 11 is equipped with a display screen and control switches.

[0043] It should be noted that both the display screen and the control switch can be used in conjunction with the control module, which are mature technologies well known to those skilled in the art, and will not be described in detail in this embodiment.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
