Detailed Description of the Embodiment

[0025] As Figure 1-2 shown, a quick-switching positioning device includes a fixed mounting plate 1, a tooling platform 2 is arranged above the fixed mounting plate 1, a linear slide rail 3 is fixedly mounted on the top of the fixed mounting plate 1, the tooling platform 2 and the linear slide rail 3 are slidably connected through a sliding component 4, at least two positioning blocks 5 are arranged at intervals on one side of the fixed mounting plate 1 along the same straight line and are parallel to the linear slide rail 3, a positioning component 7 is arranged on one side of the tooling platform 2 close to the positioning block 5, and the positioning component 7 matches the positioning block 5.

[0026] During specific use, first quickly install the required positioning tooling on the tooling platform 2, and then push the tooling platform 2. The tooling platform 2 slides along the linear slide rail 3 through the sliding component 4, thereby driving the positioning tooling to move. When the tooling platform 2 drives the positioning tooling to slide to the required position, the positioning component 7 on one side of the tooling platform 2 is connected to the corresponding positioning block 5, realizing precise positioning of the tooling platform 2.

[0027] With such a design, not only can the positioning tooling be quickly installed and positioned, and the precise and rapid sliding positioning of the tooling platform 2 be achieved, reducing the preparation and adjustment time; the positioning accuracy is enhanced, and the position is ensured to be accurate through the cooperation of the linear slide rail 3 and the positioning block 5, which is applicable to production with high precision requirements; at the same time, it has high flexibility, can adapt to various production requirements and product specifications, and is convenient for replacing the positioning tooling; in addition, the structure is simple and compact, the operation is convenient, the space is saved, the production cost is low, the maintenance difficulty is low and the maintenance cost is low.

[0028] A plurality of pin holes 21 are penetrated and opened on the tooling platform 2.

[0029] With such a design, it is convenient to quickly replace or switch different toolings.

[0030] The sliding assembly 4 includes a slider 41 fixedly installed at the bottom of the tooling platform 2. A chute is opened at the bottom of the slider 41, and the chute is connected to the linear slide rail 3 through balls.

[0031] An oil injection joint 42 is opened on one outer wall of the slider 41, and the oil injection end of the oil injection joint 42 penetrates through the slider 41 and extends into the chute.

[0032] When it is necessary to move the tooling platform 2, an external force is applied to push the tooling platform 2. At this time, the slider 41 fixed at the bottom of the tooling platform 2 moves together with the platform. The balls in the chute at the bottom of the slider 41 start to rotate due to contact with the linear slide rail 3 under the action of friction, ensuring that the balls roll along the established direction of the linear slide rail 3, providing a stable guide for the movement of the tooling platform 2.

[0033] After the sliding assembly 4 works for a period of time, if it is found that the friction between the balls and the linear slide rail 3 increases or there is a jamming phenomenon, lubrication and maintenance can be carried out through the oil injection joint 42 on one outer wall of the slider 41. The lubricating oil is injected through the oil injection joint 42, and the lubricating oil flows into the chute through the oil injection end penetrating through the slider 41, directly reaching the contact part between the balls and the slide rail. A lubricating oil film is formed between the balls and the linear slide rail 3, reducing the friction coefficient, reducing wear and heat generation, and ensuring the smooth operation of the sliding assembly 4.

[0034] With such a design, firstly, the setting of the balls makes the movement of the tooling platform 2 smoother. Compared with traditional sliding friction, the resistance of rolling friction is greatly reduced. Not only can the tooling platform 2 be easily moved on the linear slide rail 3, improving work efficiency, but also wear is greatly reduced, the frequency of replacing components is reduced, the service life of the sliding assembly 4 is extended, and thus the maintenance cost is saved.

[0035] Second, by regularly injecting lubricating oil into the oil filling joint 42, the contact part between the ball and the slide rail is lubricated, thereby further reducing friction and wear and maintaining the good working state of the sliding assembly 4. At the same time, timely lubrication can also prevent the components from rusting and corroding, improving the reliability of the entire system.

[0036] A positioning hole 6 is formed at a position near the center of the top of the positioning block 5.

[0037] The positioning assembly 7 includes a connecting plate 71 integrally connected to the tooling platform 2. A positioning pin seat 72 is arranged on the top of the connecting plate 71, and a self-lubricating bushing 73 is fixedly embedded at a position corresponding to the positioning pin seat 72 on the connecting plate 71.

[0038] With such a design, the self-lubricating bushing 73 is fixedly embedded at a position corresponding to the positioning pin seat 72 on the connecting plate 71, which not only provides an accurate guide for the positioning pin 74, but also reduces the friction between the positioning pin 74 and the connecting plate 71 due to the use of the self-lubricating bushing 73, enabling the positioning pin 74 to be inserted and pulled out more smoothly, and improving the speed and accuracy of positioning.

[0039] A positioning pin 74 is movably inserted into the positioning pin seat 72. The top end of the positioning pin 74 extends above the positioning pin seat 72 and is connected with a wing nut 75. An open pin 76 is installed on the outer side wall of the positioning pin 74 near the upper position of the wing nut 75.

[0040] With such a design, first, the wing nut 75 is connected to the top end of the pin, which is convenient for the operator to perform manual operations, so that the positioning pin 74 can be easily inserted into or pulled out of the positioning pin seat 72, realizing the rapid positioning and unlocking of the tooling platform 2 and improving the work efficiency.

[0041] Secondly, by installing the open pin 76 on the outer side wall of the positioning pin 74 near the upper position of the wing nut 75, it prevents the wing nut 75 and the positioning pin 74 from disengaging due to rotation.

[0042] The bottom end of the positioning pin 74 sequentially passes through the positioning pin seat 72 and the self-lubricating bushing 73 and extends below the connecting plate 71, and the bottom end of the positioning pin 74 is matched with the positioning hole 6.

[0043] A positioning groove 77 with an inverted L-shaped structure is formed on the outer side wall of the positioning pin seat 72. The positioning groove 77 includes a longitudinally guiding groove 771 and a pin transverse stop groove 772 that are communicated with each other.

[0044] A pin stop shaft 78 is fixedly installed on the outer side wall of the positioning pin 74. The other end of the pin stop shaft 78 passes through the positioning groove 77 and extends to the outside of the positioning pin seat 72.

[0045] A spring 79 is sleeved outside the positioning pin 74, and two ends of the spring 79 are respectively in contact with the inner wall of the top of the positioning pin seat 72 and the pin stop shaft 78.

[0046] During use, first pull up the wing nut 75, so that the wing nut 75 pulls up the positioning pin 74. The positioning pin 74 moves upward in the positioning pin seat 72. At this time, the pin stop shaft 78 slides upward synchronously along the longitudinal guide groove 771. The bottom end of the positioning pin 74 gradually moves out of the positioning hole 6 and retracts into the positioning pin seat 72 and the self-lubricating bushing 73. When the bottom end of the positioning pin 74 completely moves out of the positioning hole 6 and enters the self-lubricating bushing 73, at this time, rotate the wing nut 75. The wing nut 75 drives the positioning pin 74 to rotate. The rotation of the positioning pin 74 drives the pin stop shaft 78 to enter the pin transverse stop groove 772 from the longitudinal guide groove 771. At this time, the positioning pin 74 is fixed in the current position and cannot move up and down, so that the tooling platform 2 can be conveniently moved.

[0047] When the tooling platform 2 moves to a suitable position, first rotate the wing nut 75. The wing nut 75 drives the positioning pin 74 to rotate. The rotation of the positioning pin 74 drives the pin stop shaft 78 to enter the longitudinal guide groove 771 from the pin transverse stop groove 772. Loosen the wing nut 75. Under the elastic force of the spring 79, the positioning pin 74 starts to move downward, and the positioning pin 74 is inserted into the positioning hole 6 to realize the positioning of the tooling platform 2.

[0048] With such a design, the tooling platform 2 can quickly switch positions according to the vehicle model to achieve the positioning effect, without customizing special tooling, reducing the production investment cost, improving the flexibility of the production line, and greatly improving the production efficiency of the production line.

[0049] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions and variations made to the embodiments still fall within the protection scope of the present invention.
