Description

Technical Field

[0001] This utility model relates to the field of gripper disassembly technology, specifically a positioning device that allows for quick gripper replacement. Background Technology

[0002] In modern industrial production, especially in automobile manufacturing and electronic equipment production, the widespread application of automated production lines has greatly improved production efficiency and product quality. Gripper devices, as an important component of automated production lines, are used to grasp and transport workpieces. Their performance and reliability directly affect the efficiency and quality of the entire production process. However, traditional grippers are usually of a single structure and can only adapt to specific workpieces. When processing workpieces of different shapes or sizes, the entire gripper device needs to be replaced. This process is not only time-consuming but also reduces production efficiency and affects the production cycle. Therefore, this invention provides a positioning device with quickly replaceable grippers. Utility Model Content

[0003] The present invention aims to provide a positioning device with a quick-change gripper, which can quickly install or remove grippers of different specifications to meet different gripping needs.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A positioning device with quick-change grippers includes a base plate and a gripper mounting plate. Multiple fixing cylinders are detachably mounted on the side wall of the base plate, and multiple fixing sleeves are fixedly mounted on the side wall of the gripper mounting plate. The fixing sleeves correspond one-to-one with the fixing cylinders. The base plate and the gripper mounting plate are detachably mounted through the fixing sleeves and fixing cylinders.

[0006] The base plate is equipped with multiple positioning pins, and the side wall of the gripper mounting plate is provided with multiple positioning holes corresponding to the positioning pins.

[0007] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0008] In practical use, the grippers are first installed on the gripper mounting plate with bolts. Then, the positioning holes on the gripper mounting plate are aligned with the positioning pins, so that the gripper mounting plate is clamped onto the base plate. Then, an external hydraulic pump supplies oil to the fixed cylinder, causing the output end of the fixed cylinder to extend and squeeze the steel ball, causing the steel ball to protrude along the round hole (because the round hole is limited, the steel ball will not fall off). When the steel ball protrudes from the round hole, it can be locked in the annular groove opened inside the fixed sleeve, thereby realizing the installation and fixation between the fixed cylinder and the fixed sleeve, and thus the installation and fixation between the base plate and the gripper mounting plate. In this way, different types of grippers can be quickly disassembled and replaced to meet different gripping needs. When disassembly is required, the piston is reset to stop the pressure on the steel ball, thereby allowing the fixed sleeve to be removed from the fixed cylinder.

[0009] In a preferred embodiment, the present invention can be further configured such that: the fixed oil cylinder is detachably fixed to the base plate by bolts, and an oil inlet pipe is installed on the side wall of the fixed oil cylinder, and the oil inlet pipe is arranged through the base plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: proximity switches are fixedly installed on the side walls on both sides of the base plate, and connecting brackets are fixed on the side walls of the proximity switches, and the connecting brackets are fixed to the base plate by bolts.

[0011] In a preferred embodiment, the present invention can be further configured such that the number of fixed hydraulic cylinders is six, and the six fixed hydraulic cylinders are arranged in two rows, one above the other.

[0012] In a preferred embodiment, the present invention can be further configured such that both the base plate and the top sidewall of the gripper mounting plate are threaded with lifting bolts.

[0013] In a preferred embodiment, the present invention can be further configured such that: the side wall of the gripper mounting plate has a plurality of mounting holes.

[0014] In a preferred embodiment, the present invention can be further configured such that a plurality of stop bars are fixedly connected to the side of the base plate facing the gripper mounting plate.

[0015] In a preferred embodiment, the present invention can be further configured such that the positioning pin is made of carbon structural steel and its surface is chrome-plated.

[0016] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0017] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0018] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0019] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0020] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0021] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0022] In this invention, the detachable installation of the fixing cylinder and the fixing sleeve enables the rapid fixing and release of the grippers, allowing for quick installation or disassembly of grippers of different specifications to meet various gripping needs. Furthermore, multiple positioning pins are installed on the base plate, and multiple positioning holes are opened on the side wall of the gripper mounting plate corresponding to the positioning pins. This multi-point positioning design, combined with the precise control of the fixing cylinder, ensures high-precision positioning of the gripper mounting plate during fixing, reducing positional errors.

[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0029] Based on the concept of this application, combined with Figures 1 to 3 This document describes an embodiment of a positioning device with a quickly replaceable gripper type. Specifically, the positioning device with a quickly replaceable gripper is constructed as a split structure, comprising four components: a base plate 1, a gripper mounting plate 2, a fixing cylinder 3, and a fixing sleeve 4. The detachable installation of the fixing cylinder 3 and the fixing sleeve 4 enables rapid fixing and release of the grippers, allowing for quick installation or removal of grippers of different specifications to meet diverse gripping needs. Furthermore, the base plate 1 is equipped with multiple positioning pins 5, and the side wall of the gripper mounting plate 2 has multiple positioning holes 6 corresponding to the positioning pins 5. This multi-point positioning design, combined with the precise control of the fixing cylinder 3, ensures high-precision positioning of the gripper mounting plate 2 during fixing, reducing positional errors.

[0030] Combination Figures 1-3 As shown, the positioning device with quick-change gripper provided by this utility model includes a base plate 1 and a gripper mounting plate 2. Multiple fixing cylinders 3 are detachably installed on the side wall of the base plate 1, and multiple fixing sleeves 4 are fixedly installed on the side wall of the gripper mounting plate 2. The fixing sleeves 4 correspond one-to-one with the fixing cylinders 3. The base plate 1 and the gripper mounting plate 2 are detachably installed through the fixing sleeves 4 and the fixing cylinders 3.

[0031] Multiple positioning pins 5 are installed on the base plate 1, and multiple positioning holes 6 are opened on the side wall of the gripper mounting plate 2 at positions corresponding to the positioning pins 5.

[0032] In this embodiment, the fixed hydraulic cylinder 3 is detachably fixed to the base plate 1 by bolts. An oil inlet pipe 7 is installed on the side wall of the fixed hydraulic cylinder 3, and the oil inlet pipe 7 penetrates the base plate 1. The bolted connection simplifies and speeds up the installation and removal of the fixed hydraulic cylinder 3 from the base plate 1. When the fixed hydraulic cylinder 3 needs to be replaced or repaired, it can be removed from the base plate 1 simply by loosening the bolts, without requiring complex tools or operations, thus greatly saving time and labor costs.

[0033] It should be noted that an installation sleeve is installed on the side wall of the fixed cylinder 3. Multiple steel balls 12 are installed inside the installation sleeve. Multiple round holes 13 that are adapted to the steel balls 12 are opened on the side wall of the installation sleeve. When the steel balls 12 protrude from the round holes 13, they can be stuck in the annular groove 11 opened inside the fixed sleeve 4, thereby realizing the installation and fixation between the fixed cylinder 3 and the fixed sleeve 4, and further realizing the installation and fixation between the base plate 1 and the gripper mounting plate 2. In this way, different types of grippers can be quickly disassembled and replaced to meet different gripping needs.

[0034] It should be further explained that an oil inlet pipe 7 is installed on the side wall of the fixed cylinder 3. Hydraulic oil enters the cylinder through the oil inlet pipe 7. The oil inlet pipe 7 is laid through the base plate 1 to ensure that the hydraulic oil can flow smoothly into the cylinder. The input of hydraulic oil is controlled by the hydraulic system. The hydraulic pump provides pressure to make the hydraulic oil flow in the pipeline. There is a piston inside the fixed cylinder 3. The piston divides the cylinder into two chambers: a rod chamber and a rodless chamber. When hydraulic oil enters the rodless chamber, the piston is pressured by the hydraulic oil and pushes the piston towards the rod chamber. Conversely, when hydraulic oil enters the rod chamber, the piston is pressured by the hydraulic oil and pushes the piston towards the rodless chamber. When the piston moves towards the rod chamber, the output rod (not shown in the figure) of the fixed cylinder 3 will extend to push out multiple steel balls 12, so that the multiple steel balls 12 protrude along the circular hole 13 to achieve fixation. When disassembly is required, the piston can be reset to stop the pressure on the steel balls 12, so that the fixed sleeve 4 can be removed from the fixed cylinder 3.

[0035] It should be noted that a reading head is installed on the side wall of the base plate 1 to facilitate reading the information on the workpiece to be clamped and avoid clamping errors.

[0036] In this embodiment, proximity switches 8 are fixedly installed on the side walls of both sides of the base plate 1. Connecting brackets are fixed to the side walls of the proximity switches 8, and these brackets are bolted to the base plate 1. The proximity switches 8 are non-contact sensors capable of detecting in real time whether the gripper mounting plate 2 has reached the predetermined position. By installing the proximity switches 8 on both sides of the base plate 1, the position of the gripper mounting plate 2 can be accurately monitored, ensuring accurate alignment of the gripper during replacement and installation. The use of proximity switches 8 enables automated control and reduces manual intervention. When the gripper mounting plate 2 reaches the predetermined position, the proximity switch 8 sends a signal, triggering subsequent fixing or releasing actions, thereby improving the automation level and work efficiency of the entire device.

[0037] In this embodiment, the number of fixing cylinders 3 is six, arranged in two rows, one above the other. This arrangement effectively enhances the torsional resistance of the gripper mounting plate 2. In actual use, the gripper may be subjected to forces in various directions, especially torque. The coordinated action of the two rows of fixing cylinders 3 better resists these torques, ensuring the gripper remains stable during operation.

[0038] In this embodiment, both the base plate 1 and the gripper mounting plate 2 are threadedly connected to the top sidewalls of the base plate 1 and the gripper mounting plate 2. During installation, the lifting bolts 9 can easily lift the base plate 1 and the gripper mounting plate 2 to the designated position, and then fix and connect them. This design makes the installation process more efficient, reduces installation time and labor costs, and the threaded connection of the lifting bolts 9 to the base plate 1 and the gripper mounting plate 2 ensures a strong and reliable connection that can withstand greater tensile force, ensuring that the device will not loosen or fall off during the lifting process, thus improving the safety of the lifting.

[0039] Regarding the technical solution of this embodiment, multiple mounting holes are provided on the side wall of the gripper mounting plate 2. Different types or specifications of grippers (not shown in the figure) can be installed through the mounting holes to meet different usage requirements.

[0040] Regarding the technical solution of this embodiment, a plurality of stop rods 10 are fixedly connected to the side of the base plate 1 facing the gripper mounting plate 2. The stop rods 10 are used to control the installation position between the gripper mounting plate 2 and the base plate 1. When the gripper mounting plate 2 is fixed to the base plate 1, the stop rods 10 abut against the side wall of the gripper mounting plate 2.

[0041] Regarding the technical solution of this embodiment, the positioning pin 5 is made of carbon structural steel and its surface is chrome-plated. When the gripper mounting plate 2 is installed with the base plate 1, the positioning hole 6 on the gripper mounting plate 2 is aligned with the positioning pin 5 to provide positioning guidance, so that the gripper mounting plate 2 and the base plate 1 are installed perpendicularly.

[0042] Specifically, in actual use, the gripper is first installed on the gripper mounting plate 2 with bolts. Then, the positioning hole 6 on the gripper mounting plate 2 is aligned with the positioning pin 5, so that the gripper mounting plate 2 is locked onto the base plate 1. Then, the external hydraulic pump supplies oil to the fixed cylinder 3, causing the output end of the fixed cylinder 3 to extend and squeeze the steel ball 12, so that the steel ball 12 protrudes along the round hole 13 (because the round hole 13 is restrictive, the steel ball 12 will not fall off). When the steel ball 12 protrudes from the round hole 13, it can be locked in the annular groove 11 opened inside the fixed sleeve 4, thereby realizing the installation and fixation between the fixed cylinder 3 and the fixed sleeve 4, and thus realizing the installation and fixation between the base plate 1 and the gripper mounting plate 2. In this way, different types of grippers can be quickly disassembled and replaced to meet different gripping needs. When disassembly is required, the piston is reset to stop the pressure on the steel ball 12, so that the fixed sleeve 4 can be removed from the fixed cylinder 3.

[0043] The positioning device with quickly replaceable grippers provided by this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0044] A positioning device with quick-change grippers includes a base plate 1 and a gripper mounting plate 2. Multiple fixing cylinders 3 are detachably mounted on the side wall of the base plate 1, and multiple fixing sleeves 4 are fixedly mounted on the side wall of the gripper mounting plate 2. The fixing sleeves 4 correspond one-to-one with the fixing cylinders 3. The base plate 1 and the gripper mounting plate 2 are detachably mounted through the fixing sleeves 4 and the fixing cylinders 3.

[0045] Multiple positioning pins 5 are installed on the base plate 1, and multiple positioning holes 6 are opened on the side wall of the gripper mounting plate 2 at positions corresponding to the positioning pins 5.

[0046] The working principle and usage process of this utility model are as follows: In actual use, the gripper is first installed on the gripper mounting plate 2 with bolts. Then, the positioning hole 6 on the gripper mounting plate 2 is aligned with the positioning pin 5, so that the gripper mounting plate 2 is locked onto the base plate 1. Then, the external hydraulic pump supplies oil to the fixed cylinder 3, so that the output end of the fixed cylinder 3 extends and squeezes the steel ball 12, causing the steel ball 12 to protrude along the round hole 13 (since the round hole 13 is restricted, the steel ball 12 will not fall off). When the steel ball 12 protrudes from the round hole 13, it can be locked in the annular groove 11 opened inside the fixed sleeve 4, thereby realizing the installation and fixation between the fixed cylinder 3 and the fixed sleeve 4, and thus realizing the installation and fixation between the base plate 1 and the gripper mounting plate 2. In this way, different types of grippers can be quickly disassembled and replaced to meet different gripping needs. When disassembly is required, the piston is reset to stop the pressure on the steel ball 12, thereby allowing the fixed sleeve 4 to be removed from the fixed cylinder 3.
