Technical Field

[0001] This utility model relates to the technical field of power mold frame processing fixtures, and in particular to a power mold frame processing fixture for a filling machine. Background Technology

[0002] In the manufacturing process of precision mechanical components such as the power mold frame of a filling machine, it is usually necessary to use a special fixture to accurately and stably fix them on the worktable of the machining center to ensure consistent machining accuracy. Currently, the most common fixture fixing method used in the industry is the traditional bolt clamping structure, which involves manually connecting and locking the upper and lower plates or modules of the fixture with multiple bolts.

[0003] In existing technologies, while zero-point positioning can quickly position workpieces on the power mold frame, it still requires the mating of the sub-plate and the mother plate to achieve rapid assembly and disassembly, allowing most workpieces to be processed continuously and rapidly. The mating of the sub-plate and the mother plate is generally achieved by using bolts or pneumatic methods for rapid connection. During the rapid connection process, the sub-plate and the mother plate need to be positioned together and then fixed. The positioning of the sub-plate and the mother plate is generally achieved by using multiple holes and pins for rapid positioning. However, it is difficult to insert multiple holes and pins simultaneously during positioning, which affects the positioning efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a processing fixture for the power mold frame of a filling machine, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A processing fixture for a filling machine power mold frame includes a fixed mother plate, which is used to fix the mother plate to a zero-point locator. The fixed mother plate is characterized in that a limiting recess is provided on the top side of the fixed mother plate, and an arc-shaped groove is also provided on the top of the fixed mother plate. It also includes a fixing sub-plate, which is used to install the workpiece. One end of the bottom of the fixing sub-plate is fixedly connected to a fixing rod that can be inserted into the defined recess, and the other end is fixedly connected to a locking rod corresponding to the arc groove. A limiting rod is fixedly connected to the outer periphery of the fixing rod. A side groove for inserting and rotating the limiting rod is provided on the inner periphery of the limiting hole. An insertion groove communicating with the outside is provided on the top side wall of the side groove.

[0006] In a preferred embodiment, the present invention can be further configured such that: a side positioning hole and a bottom positioning hole are respectively provided on the side wall and bottom of the locking rod; a side positioning rod and a bottom positioning rod are respectively provided inside the fixing mother plate at the side wall and bottom of the arc-shaped groove.

[0007] In a preferred embodiment, the present invention can be further configured such that: a side positioning groove and a lower positioning groove corresponding to the side positioning rod and the lower positioning rod are respectively provided in the fixing mother plate; the side positioning groove and the lower positioning groove are connected through a connecting pipe; and a spring is fixedly connected between the inner end sidewall of the side positioning groove and the end of the side positioning rod.

[0008] In a preferred embodiment, the present invention can be further configured such that: a conveying pipe is fixedly connected inside the fixed mother plate, and the end of the conveying pipe is connected to the connecting pipe for conveying air to the connecting pipe.

[0009] In a preferred embodiment, the present invention can be further configured such that, driven by fluid pressure, the side positioning rod and the lower positioning rod can slide into the side positioning hole and the lower positioning hole of the locking rod respectively, thereby forming an additional lock on the locking rod.

[0010] In a preferred embodiment, the present invention can be further configured such that the center of the arc-shaped groove is located on the rotation axis of the locking rod.

[0011] In summary, this utility model has at least one of the following beneficial technical effects: 1. This filling machine power mold frame processing fixture, through the insertion and engagement of the fixed rod and the limiting concave hole, and the rotational snap-fit ​​structure of the limiting rod and the side groove, realizes the rapid mechanical positioning and initial locking between the fixed sub-plate and the fixed mother plate. In addition, with the limitation of the side positioning rod and the lower positioning rod and the side positioning hole and the lower positioning hole, the effect of rapid positioning of the fixed sub-plate and the fixed mother plate is achieved. 2. This filling machine power mold frame processing fixture, driven by gas pressure, has a side positioning rod that moves horizontally along the side positioning groove and is precisely inserted into the side positioning hole of the locking rod; at the same time, the lower positioning rod moves upward along the lower positioning groove and is inserted into the lower positioning hole of the locking rod, so as to quickly limit and lock the locking rod, achieving the effect of quick docking between the fixed subplate and the fixed mother plate.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: Refer to Figure 1 - Figure 4 The present invention discloses a processing fixture for a filling machine power mold frame, including a fixed mother plate 1, which is used to fix on a zero point locator. A limiting recess 2 is provided on the top side of the fixed mother plate 1, and an arc groove 3 is also provided on the top of the fixed mother plate 1. It also includes a fixing sub-plate 4, which is used to install the workpiece. One end of its bottom is fixedly connected to a fixing rod 5 that can be inserted into the defined recess 2, and the other end is fixedly connected to a locking rod 6 corresponding to the arc groove 3. A limiting rod 7 is fixedly connected to the outer periphery of the fixing rod 5. A side groove 8 is provided on the inner periphery of the limiting concave hole 2 for the limiting rod 7 to be inserted and rotated. An insertion groove 9 communicating with the outside is provided on the top side wall of the side groove 8.

[0020] In this embodiment, during installation, the operator places the fixing sub-plate 4 perpendicular to the fixing mother plate 1, aligning the fixing rod 5 with the limiting recess 2 and the limiting rod 7 with the insertion slot 9 and inserting it. This achieves a simple guiding and initial positioning effect without repeated adjustments, reducing operational difficulty. Subsequently, the fixing sub-plate 4 is rotated, and the limiting rod 7 slides from the insertion slot 9 into the side groove 8. After rotation into place, the upper and lower side walls of the limiting rod 7 are restricted between the upper and lower side walls of the side groove 8, thereby locking the fixing rod 5 axially and preventing it from coming out. This achieves rapid initial positioning during the docking process between the fixing sub-plate 4 and the fixing mother plate 1, reducing the positioning time between the fixing sub-plate 4 and the fixing mother plate 1 and improving the positioning efficiency between the two.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 - Figure 4As shown, the locking rod 6 has a side positioning hole 10 and a lower positioning hole 11 respectively on its side wall and bottom; the fixing mother plate 1 has a side positioning rod 12 and a lower positioning rod 13 respectively located on the side wall and bottom of the arc groove 3, and the fixing mother plate 1 has a side positioning groove 14 and a lower positioning groove 15 respectively corresponding to the side positioning rod 12 and the lower positioning rod 13.

[0022] In this embodiment, reference Figure 2 - Figure 4 After the fixed subplate 4 is rotated and locked, the locking rod 6 is located in the predetermined position within the arc groove 3. When the fixed subplate 4 is rotated and locked, the locking rod 6 is located in the predetermined position within the arc groove 3. The controllable side positioning rod 12 is inserted into the side positioning hole 10, and the lower positioning rod 13 is inserted into the lower positioning hole 11. This allows the locking rod 6 to be completely locked from two orthogonal directions. In addition to preventing disengagement, it provides additional locking force, effectively resisting cutting forces and vibrations during processing, enhancing the rigidity and stability of the fixture, and providing a guarantee for high-precision processing.

[0023] In a further preferred embodiment of this utility model, such as Figure 2 - Figure 4 As shown, the side positioning groove 14 and the lower positioning groove 15 are connected by a connecting pipe 17. A spring 16 is fixedly connected between the inner end side wall of the side positioning groove 14 and the end of the side positioning rod 12. A conveying pipe 18 is fixedly connected inside the fixing mother plate 1. The end of the conveying pipe 18 is connected to the connecting pipe 17 and is used to convey air to the connecting pipe 17.

[0024] In this embodiment, refer to the figure. Figure 2 - Figure 4 An air supply pipe connected to a conveying pipeline is connected to the outside of the fixed mother plate 1. An air pump can be connected to the input end of the air supply pipe to inject air into the conveying pipe. When the air enters the connecting pipe 17, it can act on the ends of the side positioning rod 12 and the lower positioning rod 13 at the same pressure, thereby pushing the side positioning rod 12 and the lower positioning rod 13 into the side positioning hole 10 and the lower positioning hole 11 respectively, achieving the effect of rapid control and positioning. The side positioning rod 12 and the lower positioning rod 13 are sealed in the side positioning groove 14 and the lower positioning groove 15 respectively to prevent air leakage. The spring 16 is used to drive the side positioning rod 12 to return to its original position after air leakage, while the lower positioning rod 13 will return to its original position by gravity.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 - Figure 4As shown, the side positioning rod 12 and the lower positioning rod 13 can slide into the side positioning hole 10 and the lower positioning hole 11 of the locking rod 6 respectively under the drive of fluid pressure, forming an additional lock on the locking rod 6.

[0026] In this embodiment, reference Figure 2 - Figure 4 Driven by gas pressure, the side positioning rod 12 moves horizontally along the side positioning groove 14 and is precisely inserted into the side positioning hole 10 of the locking rod 6; at the same time, the lower positioning rod 13 moves upward along the lower positioning groove 15 and is inserted into the lower positioning hole 11 of the locking rod 6, so as to quickly limit and lock the locking rod 6, thereby achieving the effect of quick docking between the fixed subplate 4 and the fixed mother plate 1.

[0027] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the center of the arc-shaped groove 3 is located on the rotation axis of the locking rod 6.

[0028] In this embodiment, reference Figure 2 - Figure 4 Since the locking rod 6 rotates around the axis of the fixing rod 5 with the fixing sub-plate 4, its movement trajectory is itself an arc. When the center of the arc groove 3 coincides with this axis of rotation, the locking rod 6 can smoothly enter the arc groove 3 during rotation, so as to facilitate stable docking between the fixing sub-plate 4 and the fixing mother plate 1.

[0029] The implementation principle of the above embodiment is as follows: During installation, the operator places the fixing subplate 4 perpendicular to the fixing mother plate 1, aligns the fixing rod 5 with the limiting recess 2, and simultaneously aligns the limiting rod 7 with the insertion slot 9 and inserts it, which can achieve a simple guiding and preliminary positioning effect. After the fixing subplate 4 is rotated and locked, the locking rod 6 is located in the predetermined position in the arc groove 3. After the fixing subplate 4 is rotated and locked, the locking rod 6 is located in the predetermined position in the arc groove 3. The controllable side positioning rod 12 is inserted into the side positioning hole 10, and the lower positioning rod 13 is inserted into the lower positioning hole 11, so that the locking rod 6 can be completely locked from two orthogonal directions. On the basis of preventing dislodgement, additional locking force is provided, which effectively resists the cutting force and vibration during processing, enhances the rigidity and stability of the fixture, and provides a guarantee for high-precision processing. Air is injected into the delivery pipe using an air pump. When the air enters the connecting pipe 17, it acts simultaneously and at equal pressure on the ends of the side positioning rod 12 and the lower positioning rod 13, thereby pushing the side positioning rod 12 and the lower positioning rod 13 into the side positioning hole 10 and the lower positioning hole 11 respectively, achieving the effect of rapid control and positioning.

[0030] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
