Description

Technical Field

[0001] This utility model belongs to the field of automated assembly equipment, and particularly relates to a press lower die fixing seat and an electronic press. Background Technology

[0002] Electronic presses are modern precision pressure devices that play a crucial role in the automated assembly of electronic components and small workpieces. They utilize a motor-driven slider for precise and controllable reciprocating motion, and a CNC system provides high-precision, programmable control over parameters such as pressure, stroke, and speed, significantly improving the automation level and process flexibility of related assembly processes. In this equipment, the lower die holder is a key component, responsible for the stable support and precise fixation of the lower die (or concave die, positioning fixture) on the worktable. However, a common technical problem is that the lower die is often installed using a fixed fixture or an integral base. This design, with its dimensions and clamping range fixed during manufacturing, cannot be adjusted to accommodate different sizes or shapes of molds required for actual assembly, and can only fit a single specification of tooling. This lack of versatility leads to inefficiency when users change molds for different assembly tasks (requiring replacement of the entire fixture or worktable), increasing equipment downtime and fixture management costs, and hindering the production line's ability to quickly switch between different products. Summary of the Invention

[0003] In view of the above-mentioned problems in the existing technology, the present invention provides a press lower die fixing seat, which includes a quadrilateral mounting plate, and a movable corner clamp that can slide from the top corner of the mounting plate to the center, wherein the movable corner clamp is a right angle shape.

[0004] The mounting plate is provided with several main sliding grooves extending from the top corner to the center, and the movable corner clamp is provided with main bolt holes. The movable corner clamp is fixed or slidably installed on the mounting plate by the main bolts passing through the main bolt holes and the main sliding grooves.

[0005] The mounting plate is also provided with a secondary slide groove parallel to the main slide groove, and the movable angle clamp is provided with a secondary bolt hole corresponding to the secondary slide groove. The secondary bolt hole and the corresponding secondary slide groove are provided with the same secondary bolt, pin or rivet.

[0006] The main slide groove is arranged along the diagonal of the mounting plate, and the secondary slide grooves are symmetrically arranged on both sides of the main slide groove; the main bolt hole is located at the corner of the movable angle clamp, and the movable angle clamp has corresponding secondary bolt holes on both sides of the main bolt hole.

[0007] The press lower die fixing seat also includes a lifting seat, a shaft seat is provided at the center of the lifting seat, a limit post is provided at the center of the shaft seat, and a circular hole matching the limit post is provided at the center of the mounting plate. The mounting plate is rotatably mounted to the shaft seat through the shaft cooperation between the circular hole and the limit post, and the mounting plate is then fixedly connected to the shaft seat by bolts.

[0008] The upper surface of the limiting post protrudes beyond the upper surface of the mounting plate.

[0009] This utility model also provides an electronic press, which is equipped with a lower die fixing seat as described above, and the die is fixed by the lower die fixing seat.

[0010] The beneficial effects of this invention are as follows: By incorporating a right-angled movable corner clamp that can slide from the top corner of the mounting plate towards the center, the fixed base overcomes the core defect of traditional fixed fixtures that cannot adapt to molds of different sizes. This design allows the position of the corner clamp to be freely adjusted, significantly expanding the range of sizes of lower molds that can be fixed and improving the versatility of the fixed base—one set of fixed bases can safely and stably install lower molds of various sizes, greatly reducing downtime caused by changing fixtures and the management costs of special tooling, thereby improving the utilization rate of the electronic press and the flexibility of the production line.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Example 1: A press lower die fixing seat.

[0017] As attached Figure 1The illustrated press lower die fixing base includes a square mounting plate 1 and three right-angled movable corner clamps 2. The mounting plate 1 has three main slide grooves 3 extending from the three apex corners towards the center, arranged along the diagonals of the mounting plate 1. Symmetrically, on both sides of each main slide groove 3, the mounting plate 1 has one secondary slide groove 4, meaning each main slide groove 3 mates with two secondary slide grooves 4, and both secondary slide grooves 4 are parallel to the main slide grooves 3. The three movable corner clamps 2 are slidably mounted onto the three main slide grooves 3, allowing them to slide from the apex corner of the mounting plate 1 towards the center. The movable angle clamp 2 has a main bolt hole 5 at its corner. The main bolt hole 5 is a countersunk bolt hole. The movable angle clamp 2 is fixed or slidably installed on the mounting plate 1 by the main bolt passing through the main bolt hole 5 and the main slide groove 3. When the nut of the main bolt is loosened, the movable angle clamp 2 can slide freely under the limit of the main bolt and the main slide groove 3. When the main bolt is tightened, the movable angle clamp 2 is clamped and fixed on the mounting plate 1 by the cooperation of the main bolt and the nut. The movable angle clamp 2 has two auxiliary bolt holes 6 symmetrically arranged on both sides of the main bolt hole 5. The auxiliary bolt holes 6 and the corresponding auxiliary slide grooves 4 correspond one-to-one. The auxiliary bolt holes 6 and the corresponding auxiliary slide grooves 4 are penetrated by the same auxiliary bolt, pin or rivet. The auxiliary bolt holes 6 and the auxiliary slide grooves 4 are mainly used to improve the sliding stability of the movable angle clamp 2 and prevent the movable angle clamp 2 from rotating. If auxiliary bolts are used, their function is the same as that of the main bolts, which can improve the tightness of the movable angle clamp 2 and the mounting plate 1 and increase the upper limit of the force on the movable angle clamp 2. However, the locking and unlocking steps are relatively cumbersome. If pins or rivets are used, the rivets do not lock the movable angle clamp 2. The rivets and pins play the role of limiting and guiding and improving the rotation resistance. Compared with auxiliary bolts, the tightening and lifting capacity of rivets and pins is relatively poor, but the sliding of the movable angle clamp 2 is more convenient. Only the nut of the main bolt needs to be loosened, without having to loosen the nut of the main bolt and the nuts of the two auxiliary bolts. This has higher efficiency and better user experience. In actual use, different fastening connectors can be selected according to the needs.

[0018] When using the fixed base, after placing the lower mold at the center of the mounting plate 1, the three movable corner clamps 2 can be flexibly slid to their corresponding apex positions and locked in place according to the actual size of the lower mold. In practical applications, two or four movable corner clamps 2 can also be set as needed. If only two movable corner clamps 2 are set, they can only be set on the same diagonal, and the cooperation of the movable corner clamps 2 will form a limit on the lower mold in the horizontal direction.

[0019] Example 2: A press lower die fixing seat.

[0020] The difference between this embodiment and Embodiment 1 is the addition of a lifting seat 7, as shown in the attached figure. Figure 2 and 3The press lower die fixing seat shown also includes a lifting seat 7, a shaft seat 8 is provided at the center of the lifting seat 7, a limit post 9 is provided at the center of the shaft seat 8, and a circular hole matching the limit post 9 is provided at the center of the mounting plate 1. The mounting plate 1 is rotatably mounted to the shaft seat 8 through the shaft cooperation between the circular hole and the limit post 9. The upper surface of the limit post 9 protrudes beyond the upper surface of the mounting plate 1. The mounting plate 1 is then fixedly connected to the shaft seat 8 by bolts.

[0021] Compared to Embodiment 1, this embodiment offers better horizontal limiting capability of the fixed seat and a better user experience. Specifically, the upward protrusion of the limiting post 9, which engages with the lower mold, further enhances the horizontal limiting capability of the lower mold. However, the lower mold requires a matching recessed hole during manufacturing, making the process relatively complex. This is suitable for pressing and assembly operations with significant lateral forces. Furthermore, the presence of the bearing seat 8, which lifts the mounting plate 1, creates an operating space between the mounting plate 1 and the lifting seat 7. The nuts for the main and auxiliary bolts can be positioned within this operating space. Compared to the fixed seat in Embodiment 1 (which requires the nuts to be positioned at the bottom of the machine base 10), the operator can more easily tighten or loosen the main and auxiliary bolts, resulting in a better user experience.

[0022] Example 3: An electronic press.

[0023] As attached Figure 1-4 An electronic press is shown, which includes a machine base 10. The machine base 10 is equipped with a lower mold fixing seat as described in Embodiment 1 and Embodiment 2, and the mold can be fixed by the lower mold fixing seat. The machine base 10 is provided with a corresponding pressing cylinder 11 on one side of the lower mold fixing seat. The pressing cylinder 11 is fixedly installed with a corresponding upper mold. The pressing cylinder 11 drives the upper mold and the lower mold to cooperate and complete the pressing assembly operation.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
