Abstract
Description
Technical Field
[0001] This utility model belongs to the field of suction nozzle gripping technology, and particularly relates to a gripper suction nozzle. Background Technology
[0002] The rapid development of modern industry has led to the replacement of manual labor with machinery in the processing of various mechanical parts, reducing the manpower required for mechanical parts processing and improving the efficiency of mechanical parts processing. In the process of using machinery to process parts, the mechanical gripping of parts is divided into clamping and negative pressure adsorption. Negative pressure adsorption usually uses a suction nozzle to adsorb parts.
[0003] In existing gripper nozzles, most devices use mechanical grippers to hold items. However, due to the nature of the material itself, mechanical grippers are prone to wear or corrosion in harsh environments such as high temperature, dust, and humidity. This can lead to movement jamming or a decrease in gripping force. In view of this, we propose the gripper nozzle. Utility Model Content
[0004] The purpose of this invention is to provide a gripper nozzle to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a gripper nozzle, comprising:
[0006] A fixed column has a cavity inside, and a sliding sleeve is provided inside the cavity. The outer side wall of the sliding sleeve is slidably connected to the inner side wall of the cavity. Two trapezoidal fixing blocks are fixedly installed on the top surface of the sliding sleeve. An annular plate is fixedly installed on the top surface of the fixed column, and the inner side wall of the annular plate is in contact with the outer side of the two trapezoidal fixing blocks respectively.
[0007] Four mounting plates are fixedly installed on both sides of the annular plate. A sliding rod is fixedly installed between two corresponding mounting plates. Two sliders are slidably installed between two sliding rods. A return spring is provided on the outer wall of each sliding rod. One end of each return spring is fixedly connected to one side of one slider, and the other end of each return spring is fixedly connected to one side of the other slider.
[0008] The shock absorber is located below the fixed column. A fixed tube is fixedly installed on the bottom surface of the shock absorber. An air intake pipe is slidably installed inside the fixed tube. The top end of the air intake pipe penetrates the outer wall of the shock absorber and extends into the cavity.
[0009] A shock-absorbing component is mounted on a shock-absorbing disc and is used to reduce the vibration felt by impacts on the overall equipment.
[0010] In the above technical solution, the shock absorption assembly further includes a shock absorption spring, which is disposed on the outer wall of the fixed column. The top end of the shock absorption spring is fixedly connected to the bottom surface of the annular plate, and the bottom end of the shock absorption spring is fixedly connected to the top surface of the shock absorption disc. A fixed seat is fixedly installed on one side of the bottom surface of the shock absorption disc. A first shock absorption rod is fixedly installed inside the air intake pipe. One end of the first shock absorption rod passes through the fixed pipe and extends to the outside. One end of the first shock absorption rod is slidably connected to the inner wall of the fixed seat. Second limiting grooves are provided on both sides of the fixed pipe, and the inner walls of the two second limiting grooves are slidably connected to the outer walls of the first shock absorption rod, respectively.
[0011] In this technical solution, when the gripper nozzle is subjected to external vibration, a shock-absorbing spring is sleeved on the outside of the fixed column, with an annular plate connected to the top and a shock-absorbing disc connected to the bottom, which can buffer the vertical impact force. One end of the first shock-absorbing rod inside the air intake pipe is slidably connected to the fixed seat, and the other end is slidably engaged with the fixed pipe through the second limiting groove, which limits the excessive displacement of the air intake pipe. The two ends of the second shock-absorbing rod inside the fixed pipe pass through the fixed pipe and are slidably engaged with the first limiting groove of the air intake pipe, further enhancing the shock absorption effect. The limiting block is fixed on the top surface of the shock-absorbing disc, with its inner sidewall slidably connected to the air intake pipe and its outer sidewall sleeved with the bottom surface of the fixed column to prevent the shock-absorbing disc from shaking excessively. This structure can minimize the damage caused by external vibration to the device and greatly improve its service life.
[0012] In the above technical solution, the shock absorption assembly further includes a second shock absorption rod, which is fixedly installed inside the fixed tube. Both ends of the second shock absorption rod pass through both sides of the fixed tube and extend to the outside. The air intake pipe has first limiting grooves on both sides, and the inner walls of the two first limiting grooves are slidably connected to the outer walls of the second shock absorption rod.
[0013] In this technical solution, when the gripper nozzle is subjected to external vibration, a shock-absorbing spring is sleeved on the outside of the fixed column, with an annular plate connected to the top and a shock-absorbing disc connected to the bottom, which can buffer the vertical impact force. One end of the first shock-absorbing rod inside the air intake pipe is slidably connected to the fixed seat, and the other end is slidably engaged with the fixed pipe through the second limiting groove, which limits the excessive displacement of the air intake pipe. The two ends of the second shock-absorbing rod inside the fixed pipe pass through the fixed pipe and are slidably engaged with the first limiting groove of the air intake pipe, further enhancing the shock absorption effect. The limiting block is fixed on the top surface of the shock-absorbing disc, with its inner sidewall slidably connected to the air intake pipe and its outer sidewall sleeved with the bottom surface of the fixed column to prevent the shock-absorbing disc from shaking excessively. This structure can minimize the damage caused by external vibration to the device and greatly improve its service life.
[0014] In the above technical solution, further, two mounting seats are fixedly installed on one side of the top surface of each of the two sliders, a fixing plate is provided above each of the two sliders, two threaded holes are opened on one side of each of the two fixing plates, and screws are threaded between the multiple mounting seats and the multiple opposite threaded holes respectively. Two first clamping plates are fixedly installed on one side of the top surface of one of the fixing plates, and a second clamping plate is fixedly installed on one side of the top surface of the other fixing plate.
[0015] In this technical solution, when the sliding sleeve rises, it drives the two trapezoidal fixing blocks to rise as well. The two trapezoidal fixing blocks slide along the two trapezoidal grooves, forcing the two sliders to move towards each other on the slide rod. This causes the two first clamping plates and the second clamping plate to move closer to each other to complete the clamping action. This structure uses the principle of air pressure to control the two first clamping plates and the second clamping plate to move closer to each other, thereby achieving the clamping of the object. This solves the problem that conventional mechanical grippers cannot be used normally in harsh environments such as high temperature, dust, and humidity due to their own material properties.
[0016] In the above technical solution, a limiting plate is further provided inside the cavity, the bottom surface of the limiting plate is fixedly connected to the bottom surface of the cavity, and the top end of the air intake pipe is fixedly connected to the bottom surface of the limiting plate.
[0017] In this technical solution, the bottom surface of the limiting plate is tightly fixed to the bottom of the cavity using a high-strength welding process, forming a stable connection structure to ensure that no displacement occurs during equipment operation. Simultaneously, the top end of the air inlet pipe is precisely fixedly connected to the bottom surface of the limiting plate, ensuring both the airtightness of gas delivery and, with the support of the limiting plate, maintaining a stable working state for the air inlet pipe.
[0018] In the above technical solution, further, a limiting block is fixedly installed on the top surface of the shock absorber, the inner side wall of the limiting block is slidably connected to the outer side wall of the air intake pipe, and the outer side wall of the limiting block is sleeved with the bottom surface of the fixed column.
[0019] In this technical solution, the intake pipe can move flexibly within a certain range while preventing it from deviating. At the same time, the outer wall of the limiting block and the bottom surface of the fixed column are precisely fitted together, and the two fit together as firmly as a mortise and tenon structure, which effectively enhances the stability and reliability of the overall structure, ensures that the various components of the equipment can work together during operation, and reduces the risk of failure caused by loose or misaligned components.
[0020] In the above technical solution, furthermore, each of the two sliders is provided with a trapezoidal groove, and the two trapezoidal fixing blocks are respectively fitted and engaged with the two trapezoidal grooves.
[0021] In this technical solution, when the sliding sleeve rises, it drives the two trapezoidal fixing blocks to rise as well. The two trapezoidal fixing blocks slide along the two trapezoidal grooves, forcing the two sliders to move towards each other on the slide rod. This causes the two first clamping plates and the second clamping plate to move closer to each other to complete the clamping action. This structure uses the principle of air pressure to control the two first clamping plates and the second clamping plate to move closer to each other, thereby achieving the clamping of the item.
[0022] The beneficial effects of this utility model are:
[0023] 1. This gripper suction nozzle, when in use, the worker first inserts one end of the air supply pipe into the air inlet pipe. After insertion, the worker checks whether the interface between the air supply pipe and the air inlet pipe is completely sealed. After checking, the other end of the air supply pipe is connected to an external negative pressure device. The negative pressure device is activated to inflate the inside of the fixed column until the inside of the fixed column is full of gas. When the inside of the fixed column is full, the sliding sleeve rises due to air pressure. When the sliding sleeve rises, it drives the two trapezoidal fixing blocks to rise as well. The two trapezoidal fixing blocks slide along the two trapezoidal grooves, forcing the two sliders to move towards each other on the sliding rod. This causes the two first clamping plates and the second clamping plate to move closer together to complete the clamping action. This structure uses the principle of air pressure to control the two first clamping plates and the second clamping plate to move closer together to achieve the clamping of the object. It solves the problem that conventional mechanical grippers cannot be used normally in harsh environments such as high temperature, dust, and humidity due to their own material.
[0024] 2. The gripper nozzle, when subjected to external vibration, has a shock-absorbing spring sleeved on the outside of the fixed column, with an annular plate connected to the top and a shock-absorbing disc connected to the bottom, which can buffer the vertical impact force. One end of the first shock-absorbing rod inside the air intake pipe is slidably connected to the fixed seat, and the other end is slidably engaged with the fixed pipe through the second limiting groove, which limits the excessive displacement of the air intake pipe. The two ends of the second shock-absorbing rod inside the fixed pipe pass through the fixed pipe and are slidably engaged with the first limiting groove of the air intake pipe, further enhancing the shock absorption effect. The limiting block is fixed to the top surface of the shock-absorbing disc, with its inner side wall slidably connected to the air intake pipe and its outer side wall sleeved with the bottom surface of the fixed column to prevent the shock-absorbing disc from shaking excessively. This structure can minimize the damage caused by external vibration to the device and greatly improve its service life. Attached Figure Description

An annular plate 3 is fixedly installed on the top surface of the fixed column 1, and the inner wall of the annular plate 3 contacts the outer side of the two trapezoidal fixing blocks 15 respectively. Four mounting plates 18 are fixedly installed on both sides of the annular plate 3. A sliding rod 19 is fixedly installed between two corresponding mounting plates 18. Two sliders 16 are slidably mounted. Each of the two sliders 19 has a return spring 20 on its outer wall.

A shock absorber assembly is installed... On the shock-absorbing plate 2, and used to reduce the vibration of the overall equipment from impacts, the gripper nozzle is used by the worker to first insert one end of the air supply pipe into the air inlet pipe 7. After insertion, check whether the interface between the air supply pipe and the air inlet pipe 7 is completely sealed. After checking, connect the other end of the air supply pipe to the external negative pressure equipment, start the negative pressure equipment to inflate the inside of the fixed column 1 until the inside of the fixed column 1 is full of gas. When the inside of the fixed column 1 is full, the sliding sleeve 14 rises due to the air pressure. When the sliding sleeve 14 rises, it drives the two trapezoidal fixing blocks 15 to rise as well. The two trapezoidal fixing blocks 15 slide along the two trapezoidal grooves 23, forcing the two sliders 16 to move towards each other on the slide rod 19. This causes the two first clamping plates 21 and the second clamping plate 22 to move closer to each other to complete the clamping action.

[0057] Example 7:
[0058] This embodiment provides a gripper nozzle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0059] Each of the two sliders 16 has a trapezoidal groove 23. The two trapezoidal fixing blocks 15 are respectively engaged with the two trapezoidal grooves 23. When the sliding sleeve 14 rises, it drives the two trapezoidal fixing blocks 15 to rise. The two trapezoidal fixing blocks 15 slide along the two trapezoidal grooves 23, forcing the two sliders 16 to move towards each other on the sliding rod 19.

This structure uses the principle of air pressure to control the two first clamping plates 21 and the second clamping plate 22 to move closer to each other, thereby achieving the clamping of the item.
[0060] In use: When using this gripper nozzle, the worker first inserts one end of the air supply pipe into the air inlet pipe 7. After insertion, check whether the interface between the air supply pipe and the air inlet pipe 7 is completely sealed. After checking, connect the other end of the air supply pipe to the external negative pressure device. Start the negative pressure device to inflate the inside of the fixed column 1 until the gas inside the fixed column 1 is full. When the inside of the fixed column 1 is full, the sliding sleeve 14 rises due to air pressure. When the sliding sleeve 14 rises, it drives the two trapezoidal fixing blocks 15 to rise as well. The two trapezoidal fixing blocks 15 slide along the two trapezoidal grooves 23, forcing the two sliders 16 to move towards each other on the sliding rod 19. This causes the two first clamping plates 21 and the second clamping plate 22 to move closer together to complete the clamping action. This structure uses the principle of air pressure to control the two first clamping plates 21 and the second clamping plate 22 to move closer together to achieve the clamping of the item. It solves the problem that conventional mechanical grippers cannot be used normally in harsh environments such as high temperature, dust, and humidity due to their own material.

One end of the first shock-absorbing rod 8 in the air intake pipe 7 is slidably connected to the fixed seat 5, and the other end is slidably engaged with the fixed pipe 6 through the second limiting groove 11, which limits the excessive displacement of the air intake pipe 7. The two ends of the second shock-absorbing rod 9 in the fixed pipe 6 pass through the fixed pipe 6 and are slidably engaged with the first limiting groove 10 of the air intake pipe 7, which further enhances the shock absorption effect. The limiting block 12 is fixed on the top surface of the shock-absorbing disc 2, with its inner side wall slidably connected to the air intake pipe 7 and its outer side wall sleeved with the bottom surface of the fixed column 1, to prevent the shock-absorbing disc 2 from shaking excessively. This structure can minimize the damage caused by external vibration to the device and greatly improve its service life.
