Description

A special fixture for multi-station milling sample machine Technical Field

[0001] This utility model relates to the field of aluminum sample processing technology, specifically a special fixture for a multi-station milling machine. Background Technology

[0002] In the aluminum sample processing, multi-station milling machines need to simultaneously clamp and mill multiple aluminum samples. However, the aluminum samples in actual production vary significantly in diameter and height, revealing numerous problems with existing fixtures:

[0003] The clamping efficiency is low, it is difficult to achieve synchronous clamping at multiple stations, and the clamping method needs to be frequently adjusted for aluminum samples of different specifications, which consumes a lot of time.

[0004] The lack of real-time clamping status detection makes it impossible to detect loose aluminum samples in time, posing a potential processing hazard.

[0005] Poor specification adaptability; existing equipment cannot effectively handle differences in aluminum sample diameter and height, making it difficult to guarantee consistent milling results and leading to inconsistent processing quality.

[0006] Therefore, there is an urgent need to design a special fixture for multi-station milling machines that is compact, has reliable clamping, and can adapt to aluminum samples of different specifications. Summary of the Invention

[0007] This utility model provides a special fixture for a multi-station milling machine to solve the problems of low clamping efficiency and poor adaptability to aluminum samples of different specifications in existing fixtures, so as to achieve efficient and safe processing of aluminum samples and ensure the consistency of milling results.

[0008] A special fixture for a multi-station milling machine includes: a support, a support mechanism mounted on the support, and a clamping mechanism. The clamping mechanism is disposed above the support mechanism and surrounds the support mechanism. The support mechanism is used to place an aluminum sample, and the clamping mechanism is used to clamp and fix the aluminum sample.

[0009] As a preferred embodiment of this utility model, the support mechanism includes a vertical plate, which is installed in the middle of the upper part of the support. Horizontal plates are fixedly installed on both sides of the vertical plate, and linear bearings are installed on the horizontal plates. Guide shafts are installed above the linear bearings, and two guide shafts are symmetrically arranged. A tray for placing aluminum samples is fixedly installed on the top of the guide shafts. A spring is fitted around the outside of the guide shafts and is located between the horizontal plates and the trays. The guide shafts and linear bearings enable the trays to move up and down, and the springs enable the trays to return to their original position.

[0010] As a preferred embodiment of this utility model, the clamping mechanism includes a fixed plate installed on the support, the fixed plate being arranged parallel to both sides of the vertical plate, a first cylinder being installed on the fixed plate, and a movable clamping plate being installed at the extended end of the first cylinder; a fixed clamping plate is installed on the top of the vertical plate, and the movable clamping plate and the fixed clamping plate cooperate to clamp and fix the aluminum sample.

[0011] In a preferred embodiment of this utility model, a guide rail is installed between the fixed plate and the vertical plate, and the movable clamping plate is slidably installed on the guide rail, which is used to guide the movable clamping plate.

[0012] As a preferred embodiment of this utility model, the first cylinder is provided with a front sensor and a rear sensor. The front sensor is located on the side near the extended end of the first cylinder and is used to check whether the movable clamping plate is clamping the aluminum sample tightly, so as to prevent individual aluminum samples from jumping out during milling because they are not clamped tightly. The rear sensor is located on the side away from the extended end of the first cylinder and is used to detect whether the movable clamping plate has returned to its original position, so as to prevent individual aluminum samples from jumping out and injuring people if they do not return to their original position.

[0013] As a preferred embodiment of this utility model, the fixed clamping plate is provided with V-shaped clamping grooves on both sides, and a number of anti-slip grooves are provided in the V-shaped clamping grooves.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This utility model, through symmetrically arranged guide shafts and support plates, can simultaneously hold multiple aluminum samples. Combined with movable and fixed clamping plates on both sides, it achieves synchronous clamping at multiple workstations, greatly improving processing efficiency. The support plates float up and down via springs and guide shafts, accommodating aluminum samples of different heights. Front and rear sensors monitor the clamping status in real time, avoiding safety hazards caused by incomplete clamping or failure to reset, thus improving processing safety. The combination of V-shaped clamping grooves and anti-slip grooves enhances clamping force, reduces displacement of the aluminum samples during milling, and ensures processing accuracy. This fixture can clamp aluminum samples of different diameters and heights, ensuring consistency after clamping, facilitating subsequent milling, and effectively guaranteeing consistent milling results.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] As shown in Figures 1 to 3, a specific embodiment of the multi-station milling machine special fixture of the present invention includes: a support 1, a support mechanism and a clamping mechanism. The support mechanism is installed on the support 1 and is used to place the aluminum sample 4. The clamping mechanism is arranged above the support mechanism and around it and is used to clamp and fix the aluminum sample 4.

[0023] Supporting institutions:

[0024] Includes a vertical plate 10, which is fixed to the upper middle position of the support 1;

[0025] A horizontal plate 11 is fixed on both sides of the vertical plate 10, and a linear bearing 14 is installed on the horizontal plate 11.

[0026] A guide shaft 15 (two symmetrically arranged) is provided above the linear bearing 14, and a support plate 8 is fixed on the top of the guide shaft 15 for placing the aluminum sample 4.

[0027] A spring 13 is fitted on the outside of the guide shaft 15. The spring 13 is located between the horizontal plate 11 and the support plate 8, so that the support plate 8 can move up and down and automatically reset.

[0028] Clamping mechanism:

[0029] Includes a fixing plate 2 arranged parallel to both sides of the vertical plate 10, a first cylinder 3 installed on the fixing plate 2, and a movable clamping plate 5 connected to the extended end of the cylinder;

[0030] A fixed clamping plate 9 is provided at the top of the vertical plate 10, and the movable clamping plate 5 cooperates with the fixed clamping plate 9 to clamp the aluminum sample 4;

[0031] A guide rail 12 is installed between the fixed plate 2 and the vertical plate 10, and the movable clamping plate 5 is slidably installed on the guide rail 12 to achieve guiding and positioning.

[0032] A front sensor 6 (near the extended end) and a rear sensor 7 (away from the extended end) are installed on the first cylinder 3 to detect whether the movable clamping plate 5 has clamped the aluminum sample 4 and whether it has reset, respectively, to avoid the risk of the aluminum sample 4 jumping out. The front sensor 6 and the rear sensor 7 are magnetic switch sensors. The sensors transmit and receive signals by detecting the change in magnetic field caused by the change in position of the permanent magnet set on the extended end (i.e., piston rod) of the first cylinder 3 during the extension or retraction of the piston rod. In this utility model, when the front sensor 6 detects that the piston rod has extended to the position, it indicates that the movable clamping plate 5 has clamped the aluminum sample 4; when the rear sensor 7 detects that the piston rod has retracted to the original position, it indicates that the movable clamping plate 5 has reset. The principle of the magnetic switch sensor detecting the change in magnetic field and transmitting and receiving signals is prior art and will not be described in detail here.

[0033] V-shaped clamping grooves are provided on both sides of the fixed clamping plate 9, and several anti-slip grooves are set in the clamping grooves to enhance the clamping friction.

[0034] In actual use, multiple sets of special fixtures can be placed side by side, as shown in Figure 3. Eight special fixtures are set as a group, and two groups are set up to process simultaneously, thereby improving processing efficiency.

[0035] The control system uses the existing Siemens S7-1200 series PLC for control.

[0036] The working principle of this utility model:

[0037] Placing aluminum sample 4: Aluminum samples 4 of different diameters and heights are placed on the support plate 8. The pressure plate (as shown in Figure 3) is pressed down to make the upper surface of the aluminum sample 4 flush. The compression spring 13 moves downward and the guide shaft 15 slides in the linear bearing 14 to achieve adaptive support and adjust the height of the aluminum sample 4 to keep it consistent. The pressure plate is controlled by the cylinder through the PLC system. The cylinder drives the pressure plate to perform pressing and resetting operations.

[0038] Clamping operation: Start the first cylinder 3, the movable clamping plate 5 moves along the guide rail 12 to the fixed clamping plate 9, and the V-shaped clamping groove and anti-slip groove cooperate to clamp the aluminum sample 4;

[0039] Status detection: The front sensor 6 detects whether the extended end (i.e., piston rod) of the first cylinder 3 has extended. If it has not extended, an alarm is issued and the next action is stopped.

[0040] Milling: After the multi-station aluminum sample 4 is clamped and fixed, the milling machine performs synchronous milling on the aluminum sample 4. After the processing is completed, the support plate 8 is reset under the action of the spring 13, which facilitates unloading.

[0041] After processing, the pressure plate is placed on the upper surface of the aluminum sample 4 again. The rear sensor 7 detects whether the extended end of the cylinder (i.e., the piston rod) has returned to its original position. If it has not returned to its original position, the unloading stops. When it returns to its original position, the pressure plate slowly opens, and the milled aluminum sample 4 can be taken out.

[0042] The components such as the first cylinder, the front sensor, and the rear sensor mentioned in this article are all general standard parts or components known to those skilled in the art, and have not been modified. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0043] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
