Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressing equipment technology, specifically to a jig locking mechanism and pressing equipment. Background Technology
[0002] In industrial production processes, products often need to be pressed or held under pressure, making pressing equipment one of the most important pieces of equipment in industrial production. Existing pressing equipment, to accommodate products of different specifications, typically uses detachable fixture plates. By replacing the fixture plate, different specifications of products can be pressed or held under pressure. However, existing pressing equipment with replaceable fixture plates usually uses bolted connections to install the fixture plate. Replacing the fixture plate requires removing and installing a large number of bolts, making the process complex and hindering automated fixture plate replacement. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a fixture locking mechanism that can reduce the difficulty of fixture plate replacement and facilitate the automated replacement of fixture plates.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a fixture locking mechanism, comprising: a fixture plate with a plurality of first locking blocks on its back; a fixture mounting plate for mounting the fixture plate, with a plurality of locking guide holes on its surface; a plurality of second locking blocks, respectively disposed in the locking guide holes and slidable along the locking guide holes, wherein one of the first locking blocks and the second locking blocks is provided with a locking groove matching the shape of the other, and the first locking block or the second locking block can be inserted into the locking groove from a first direction; a locking drive mechanism disposed on the side of the fixture mounting plate facing away from the fixture plate, the second locking blocks being connected to the locking drive mechanism, the locking drive mechanism being used to drive the second locking blocks to move along the locking guide holes in a second direction, so as to pull the end of the first locking block that is inserted into the fixture mounting plate into the locking guide hole, thereby realizing the locking of the fixture plate.
[0005] Compared to existing technologies, the advantages of this invention are as follows: By inserting the jig plate into the jig mounting plate along a first direction, the first locking block of the jig plate and the second locking block of the jig mounting plate are engaged. Then, the locking drive mechanism pulls the second locking block along a second direction toward the jig mounting plate, thereby pulling the jig plate toward the jig mounting plate, increasing the pressure between the jig plate and the jig mounting plate, increasing the static friction between them, and pulling the end of the first locking block facing the jig mounting plate into the locking guide hole. This prevents lateral relative movement between the jig plate and the jig mounting plate, thus achieving the locking of the jig plate. This jig locking mechanism can lock the jig plate without bolts, reducing the complexity of jig plate disassembly and assembly, thereby improving jig plate replacement efficiency and facilitating automatic jig plate replacement.
[0006] In the aforementioned fixture locking mechanism, the first locking block has a T-shaped cross-section, and the locking groove is located at one end of the second locking block facing the fixture plate; the locking groove is a T-shaped groove.
[0007] The aforementioned fixture locking mechanism includes a locking mechanism mounting plate, a locking lever, and a lever driving device. The locking mechanism mounting plate is disposed on the side of the fixture mounting plate facing away from the fixture plate. The locking lever is rotatably disposed between the locking mechanism mounting plate and the fixture mounting plate. The first end of the locking lever is rotatably connected to the lever driving device, and the second end of the locking lever is rotatably connected to the second locking block. The lever driving device is disposed on the locking mechanism mounting plate.
[0008] In the aforementioned fixture locking mechanism, the lever drive device is a cylinder.
[0009] In the aforementioned fixture locking mechanism, an even number of first locking blocks are provided on the back of the fixture plate, and the plurality of first locking blocks are symmetrically arranged on the fixture plate about the axis of symmetry of the fixture plate.
[0010] In the aforementioned fixture locking mechanism, multiple second locking blocks are connected to a locking connecting plate, and the second end of the locking lever is rotatably connected to the locking connecting plate.
[0011] In the aforementioned fixture locking mechanism, the locking connecting plate has a plurality of connecting bolts on the side facing the fixture plate, and the second locking block has a T-shaped connecting groove at the end facing away from the fixture plate that matches the shape of the nut end of the connecting bolt. The locking connecting plate is connected to the second locking block by inserting the nut of the connecting bolt into the connecting groove.
[0012] In the aforementioned fixture locking mechanism, both the fixture mounting plate and the fixture plate are rectangular. Guide baffles are provided on both short sides of the fixture mounting plate. The distance between the guide baffles matches the length of the fixture plate, and the first direction is parallel to the direction of the guide baffles.
[0013] In the aforementioned fixture locking mechanism, the four corners of the wider portion of the first locking block are all chamfered.
[0014] A pressing device includes the aforementioned fixture locking mechanism.

Detailed Implementation
[0023] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 5This utility model provides a fixture locking mechanism, including a fixture plate 100, a fixture mounting plate 200, second locking blocks 300, and a locking drive mechanism 400. The fixture plate 100 has a plurality of first locking blocks 110 on its back side. The fixture mounting plate 200 is used to mount the fixture plate 100, and its surface has a plurality of locking guide holes 210. A plurality of second locking blocks 300 are slidably disposed within the locking guide holes 210. One of the first locking blocks 110 and the second locking blocks 300 has a locking groove matching the shape of the other. The locking block without a locking groove can be inserted into the locking groove from a first direction, and the second locking block 300 can slide along the locking guide holes 210 in a second direction. The end of the second locking block 300 facing away from the fixture plate 100 is connected to the locking drive mechanism 400. The locking drive mechanism 400 is used to drive the second locking block 300 to move in the second direction, so as to pull the end of the first locking block 110 that is inserted with the second locking block 300 toward the fixture mounting plate 200 into the locking guide hole 210, so as to lock the fixture plate 100 onto the fixture mounting plate 200.
[0024] This fixture locking mechanism works by inserting the fixture plate 100 into the fixture mounting plate 200 along a first direction, causing the first locking block 110 and the second locking block 300 to engage. Then, the locking drive mechanism 400 drives the second locking block 300 to move along a second direction towards the fixture mounting plate 200, bringing the fixture plate 100 into contact with the fixture mounting plate 200 and pulling the first locking block 110 into the locking guide hole 210. The static friction between the fixture plate 100 and the fixture mounting plate 200, the restriction of the first locking hole's movement in the first direction by the locking guide hole 210, and the restriction of the first locking block 110's movement in the second direction by the second locking block 300, all contribute to fixing the fixture plate 100 onto the fixture mounting plate 200. The disassembly process is the reverse; the locking drive mechanism 400 first drives the second locking block 300 to move in the opposite direction of the second direction, and then moves the fixture plate 100 in the opposite direction of the first direction. The installation and disassembly of the jig plate 100 does not require the removal or installation of bolts, simplifying the installation and disassembly process and thus improving the efficiency of jig plate 100 installation and disassembly. Furthermore, during the installation and disassembly process, the jig plate 100 only needs to be inserted into the jig mounting plate 200 along the first direction, or pulled out from the jig mounting plate 200 along the opposite direction; all other actions are automatically completed by the locking drive mechanism 400. This facilitates automatic replacement of the jig plate 100 in conjunction with other equipment mechanisms and is suitable for lights-out factories.
[0025] Understandably, for ease of installation and secure locking of the jig plate 100, the first direction should preferably be parallel to the working surface of the jig plate 100, and the second direction should preferably be perpendicular to the working surface of the jig plate 100. (Refer to...) Figure 4 In this embodiment, a locking groove is disposed on the second locking block 300. The locking groove can be a T-shaped groove or a trapezoidal groove, or other irregularly shaped groove whose width increases in the second direction. In this embodiment, the locking groove is a T-shaped groove, and correspondingly, the cross-section of the end of the first locking block 110 facing the fixture mounting plate 200 is T-shaped, matching the cross-sectional shape of the locking groove. (Refer to...) Figure 2 The four corners of the wider portion of the first locking block 110 are chamfered so that the first locking block 110 can be inserted into the locking groove.
[0026] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, both the jig plate 100 and the jig mounting plate 200 are rectangular. To improve the secure fastening of the jig plate 100, four first locking blocks 110 are provided on the back of the jig plate 100. The four first locking blocks 110 are symmetrically arranged on the jig plate 100 about the axes of symmetry in the length and width directions of the jig plate 100. Correspondingly, four locking guide holes 210 are also provided at corresponding positions on the jig mounting plate 200. The shape of the locking guide holes 210 matches the cross-sectional shape of the second locking block 300 in the second direction, and the lengths of the locking guide holes 210 and the first locking blocks 110 in the first direction match. In this embodiment, to further facilitate the installation of the jig plate 100, the first direction is parallel to the direction of the wide side of the jig plate 100, and the directions of the locking grooves on the four second locking blocks 300 provided in the locking guide holes 210 are also parallel to the direction of the wide side of the jig plate 100. The jig mounting plate 200 has guide baffles 220 on both wide sides to guide the insertion direction of the jig plate 100. The distance between the two guide baffles 220 matches the length of the jig plate 100 to prevent the jig plate 100 from getting stuck during insertion because the insertion direction is not parallel to the first direction. (Refer to...) Figure 3 The two locking slots on one side of the first direction are closed at the end facing the first direction to limit the insertion stroke of the jig plate 100 in the first direction and to position the insertion position of the jig plate 100 to ensure the accuracy of the installation position of the jig plate 100.
[0027] It is understandable that the locking drive mechanism 400 can be a linear drive mechanism formed by combining drive devices such as motors, cylinders, and electric cylinders with various transmission mechanisms. (Refer to...) Figure 3 and Figure 4In this embodiment, the locking drive mechanism 400 includes a locking mechanism mounting plate 410, a locking lever 420, and a lever drive device 430. The locking mechanism mounting plate 410 is disposed on the side of the fixture mounting plate 200 facing away from the fixture plate 100, and is used to connect with a drive mechanism on the equipment for providing pressing or holding pressure, so that the pressure provided by the pressure drive mechanism can be evenly transmitted to the fixture plate 100, unaffected by the locking drive mechanism 400. In this embodiment, referring to… Figure 1 and Figure 3 The locking mechanism mounting plate 410 is connected to the fixture mounting plate 200 via a plurality of evenly arranged support columns 411. The locking lever 420 is rotatably mounted between the fixture mounting plate 200 and the locking mechanism mounting plate 410 via a support 421 mounted on the locking mechanism mounting plate 410. The first end of the locking lever 420 is rotatably connected to the lever driving device 430, and the second end is rotatably connected to the second locking block 300. In this embodiment, the lever driving device 430 is a cylinder, located on the side of the locking mechanism mounting plate 410 facing away from the fixture mounting plate 200, and the piston rod of the cylinder is rotatably connected to the first end of the locking lever 420.
[0028] Reference Figure 3 and Figure 4 In this embodiment, to improve the synchronization of the movement of the four second locking blocks 300 and ensure the stability of the locking process of the fixture plate 100, all four second locking blocks 300 are connected to the locking drive mechanism 400 through a locking connecting plate 440. The locking drive mechanism 400 includes two sets of locking levers 420 and lever drive devices 430. The two locking levers 420 and lever drive devices 430 are symmetrically arranged on the locking mechanism mounting plate 410. The second ends of the two locking levers 420 are rotatably connected to the side of the locking connecting plate 440 facing away from the fixture plate 100. For ease of installation, a connecting bolt 441 is provided at each of the four corners of the side of the locking connecting plate 440 facing the fixture plate 100. A T-shaped connecting groove is provided at one end of the second locking block 300 facing the locking connecting plate 440. The nut part of the connecting bolt 441 can be inserted into the connecting groove, thereby connecting the second locking block 300 to the locking connecting plate. Because the connecting nut is round, the direction of the second locking block 300 can still be adjusted after the second locking block 300 and the locking connecting plate 440 are connected, which makes it easier to adjust the angle of the four second locking blocks 300 during installation and improves the convenience of installation.
[0029] Reference Figure 3In this embodiment, to further ensure that the four second locking blocks 300 can move synchronously during locking, the locking connecting plate 440 is provided with several guide holes whose shapes match the shapes of the support columns 411. The support columns 411 at corresponding positions can pass through the corresponding guide holes. In this embodiment, two guide holes are symmetrically arranged on each side of the locking connecting plate 440, and the four guide columns around the locking connecting plate 440 pass through the corresponding guide holes to limit the horizontal position of the locking connecting plate 440 relative to the locking mechanism mounting plate 410. This ensures that the locking connecting plate 440 remains as parallel as possible to the fixture plate 100 during movement, and that the movements of the four second locking blocks 300 are as synchronized as possible. (Refer to...) Figure 4 In this embodiment, the lever arm length connecting the locking lever 420 to the lever drive device 430 is greater than the lever arm length connecting it to the locking connecting plate 440, thereby reducing the torque required to drive the locking mechanism and minimizing the size of the lever drive device 430. The locking lever 420 has a polygonal shape to facilitate adjustment of the stroke at both ends of the locking lever 420, making it easier to integrate the locking lever 420 into the limited space between the locking mechanism mounting plate 410 and the fixture mounting plate 200.
[0030] The pressing equipment of this utility model includes the above-mentioned fixture locking mechanism. The fixture locking mechanism can be set in the upper mold mechanism and the lower mold mechanism of the pressing equipment, which facilitates the replacement of the fixture plate 100 in the upper and lower molds and facilitates the fully automatic replacement of the fixture plate 100 of the pressing equipment.
