Description

Technical Field

[0001] This utility model relates to the field of balancing counterweight tooling technology, specifically a tooling with an automatically extendable and adjustable balancing counterweight. Background Technology

[0002] In current industrial production and logistics, electric forklifts and similar equipment are widely used for handling and loading / unloading goods. These devices typically employ a fixed counterweight design, meaning the counterweight is pre-set and cannot be dynamically adjusted according to actual needs. This design performs well with goods within a specific weight range, but when handling heavier items, additional counterweights must be added to ensure the stability and safety of the equipment.

[0003] However, adding counterweights generally brings a series of problems. First, the equipment's weight increases, raising manufacturing costs and making it more cumbersome to move and operate, affecting its flexibility and efficiency. Second, fixed counterweights cannot adapt to changes in cargo weight. In practice, cargo weight may fluctuate due to various factors, and fixed counterweight equipment cannot adjust accordingly, potentially causing imbalance during handling or even tipping over. Furthermore, with the continuous development of industrial production and the increasing demands of logistics, the requirements for equipment adaptability and flexibility are also rising. Fixed counterweight equipment is no longer sufficient for some special scenarios, such as cargo handling in confined spaces and high-precision loading and unloading operations.

[0004] In summary, a tooling device with an automatically extendable and adjustable counterweight is needed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatically extendable and adjustable counterweight fixture includes a counterweight box. Two hydraulic cylinders are mounted on opposite sides of the bottom of the counterweight box, and both cylinders are mounted on a bottom protective plate. A slide rail is provided on the bottom of the counterweight box on one side of each hydraulic cylinder. A suction cup base is mounted on the bottom of the slide rail. A four-bar linkage lifting assembly is mounted on the top of the suction cup base. A rotating fixture is mounted on one side of the four-bar linkage lifting assembly, and a connecting rod is mounted on one side of the rotating fixture. A gravity sensor is mounted on the connecting rod, and a clamping support rod is mounted on the bottom of the connecting rod. A clamping assembly is located at the bottom of the clamping support rod, and a gravity sensor is mounted on the clamping support rod. The weight of the object clamped by the grippers is calculated by the gravity sensor on the clamping support rod, and the signal is sent to the automatically calculated hydraulic cylinder to move backward, thus achieving left-right weight balance. The clamping assembly consists of four identical drive components, each with a gripper mounted on its bottom.

[0008] Preferably, each hydraulic cylinder has an output shaft fixedly connected to the side near the slide rail, a slide rod is sleeved on the outside of the output shaft, the slide rod is snapped into the inside of the slide rail, the slide rod and the slide rail are slidably connected, and the end of the output shaft is fixedly connected to the end of the inside of the slide rail.

[0009] Preferably, the counterweight box is provided with a counterweight block inside.

[0010] Preferably, an operating platform is installed on the top of the counterweight box on the side away from the clamping assembly.

[0011] Preferably, the suction cup base and the four-bar linkage lifting assembly are connected by an electric telescopic rod, and rollers are installed at the bottom of the counterweight box and at the ends of the two slide rails.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model achieves automatic telescopic adjustment of the counterweight through the combined use of a gravity sensor and a hydraulic cylinder, ensuring that the tooling maintains balance when clamping objects of different weights.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] An automatically telescopic and adjustable counterweight fixture includes a counterweight box 1. A hydraulic cylinder 3 is installed on each side of the bottom of the counterweight box 1. The two hydraulic cylinders 3 are mounted on a bottom protective plate 5 at the bottom of the counterweight box 1. A slide rail 6 is provided on the bottom of the counterweight box 1 on one side of the hydraulic cylinder 3. A suction cup base 7 is installed at the bottom of the slide rail 6. A four-bar lifting assembly 15 is provided on the top of the suction cup base 7. A rotating fixture 14 is installed on one side of the four-bar lifting assembly 15. A connecting rod 13 is installed on one side of the rotating fixture 14. A clamping support rod 12 is installed at the bottom of the connecting rod 13. A clamping assembly 11 is provided at the bottom of the clamping support rod 12. A gravity sensor is installed on the clamping support rod 12. The weight of the object clamped by the gripper 9 is calculated by the gravity sensor installed on the clamping support rod 12. The signal is sent to the automatically calculated hydraulic cylinder to move backward, achieving left-right weight balance. The clamping assembly 11 consists of four identical drive assemblies 10, each drive assembly 10 having a gripper 9 installed at its bottom.

[0020] It should also be noted that each hydraulic cylinder 3 is fixedly connected to an output shaft 4 on the side near the slide rail 6. A slide rod 16 is sleeved on the outside of the output shaft 4. The slide rod 16 is snapped into the inside of the slide rail 6. The slide rod 16 and the slide rail 6 are slidably connected. The end of the output shaft 4 is fixedly connected to the inside end of the slide rail 6. A counterweight block 17 is provided inside the counterweight box 1.

[0021] It should also be noted that an operating table 2 is installed on the top of the counterweight box 1 on the side away from the clamping assembly 11. The operating table 2 provides a convenient operating interface for operators to control various functions of the tooling.

[0022] It should also be noted that the suction cup base 7 and the four-bar lifting assembly 15 are connected by an electric telescopic rod. Rollers 8 are installed at the bottom of the counterweight box 1 and at the ends of the two slide rails 6. The rollers 8 at the bottom of the counterweight box 1 allow the entire fixture to be easily moved to different working positions.

[0023] In practical applications, the four grippers 9 of the clamping assembly 11 of this utility model tightly clamp the object to be processed under the drive of the drive assembly 10. The gravity sensor on the connecting rod 13 monitors the weight of the clamped object in real time and transmits the data to the control system. The control system calculates the amount of counterweight adjustment required to maintain the balance of the tooling based on the weight data fed back by the gravity sensor. Under the command of the control system, the hydraulic cylinder 3 drives the slide rail 6 to move in a predetermined direction through the output shaft 4 and the slide rod 16 to adjust the relative position between the counterweight box 1 and the clamping assembly 11.

[0024] Through the above steps, the combined use of gravity sensors and hydraulic cylinders enables automatic telescopic adjustment of the counterweight, ensuring that the tooling can maintain balance when clamping objects of different weights. At the same time, the four-bar lifting assembly 15, driven by the electric telescopic rod, adjusts the height and tilt angle of the rotating tooling 14, connecting rod 13, and clamping assembly 11 to further optimize the balance.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
