Description

Technical field:

Generally, manual installation is laborious, and O-rings are easily damaged due to transitional deformation, which shortens their service life. In order to facilitate the installation of O-rings, other tools have emerged. For example, the Chinese utility model patent (Announcement No. CN204108629U, application date 2014.10.20, announcement date 2015.01.21) discloses a tool for installing an O-ring (i.e., an O-ring) on ​​an oxygen bomb valve core, including a tool body, the two ends of which have different outer diameters, and the middle is a part with a smooth transition of the outer diameter.

The inner side walls of the semicircular holes 9 are concave to form semicircular grooves 10. The two semicircular grooves 10 form clamping grooves that match the O-ring 1. When the head of the sleeve rod 3 enters the clamping device, the left clamping block 7 and the right clamping block 8 are gradually separated under the action of the sleeve rod 3; when the head of the sleeve rod 3 leaves the clamping device, the left clamping block 7 and the right clamping block 8 are gradually brought together under the elastic force of the elastic member 1.

[0063] The installation structure of the left clamp block 7 and the right clamp block 8 can be: the left clamp block 7 and the right clamp block 8 are respectively installed on the two clamping claws of the finger cylinder 2 30 that is not connected to air.

When the feeding block 37 is in the first working position, the feeding groove 38 is connected to the guide device; when the feeding block 37 is in the second working position, the feeding groove 38 is connected to the clamping groove.

[0084] Feeding working principle: Figure 4 As shown, when the feed block 37 is in the first working position, the O-ring 1 of the guide device falls into the feed trough 38, and the power device 3 drives the feed block 37 to move horizontally to the second working position, and the O-ring 1 in the feed trough 38 falls into the clamping groove.

[0085] Furthermore, when the head of the sleeve rod 3 has not completely exited the clamping device, the opening block 18 is located between the left clamping block 7 and the right clamping block 8, which helps to stabilize the movement of the sleeve rod 3.

[0086] The structure of the power device 3 is as follows: the power device includes a cylinder and a guide seat, the piston rod of the cylinder is connected to one end of the feed block 37, the middle part of the feed block 37 is slidably arranged in the guide seat, and the movement of the piston rod of the cylinder drives the feed block 37 to move. The guide seat is used for guidance, which is wear-resistant and stable in operation.

[0087] In order to prevent the feeding block 37 from moving out of position, a limit block 39 is provided on the front side of the feeding block 37 to limit the lateral movement of the feeding block 37 , and the limit block 39 is installed on the installation frame 36 .

[0088] Specific structure of the clamping device: the left clamp block 7 and the right clamp block 8 are respectively arranged on the two clamping claws of the single-action normally closed finger cylinder, and the elastic member 1 is a spring arranged inside the single-action normally closed finger cylinder. When there is no force acting, the two clamping claws of the single-action normally closed finger cylinder move toward the middle, that is, the left clamp block 7 and the right clamp block 8 are in a close state.

[0089] Furthermore, the single-acting normally closed finger cylinder is connected to an air pipe, and when the O-ring 1 falls off and is misplaced, the single-acting normally closed finger cylinder can be ventilated to open the single-acting normally closed finger cylinder so as to clean the O-ring 1.

[0090] Furthermore, the second power device is a gas-buffered cylinder, and the second push rod is a piston rod of the gas-buffered cylinder. The gas-buffered cylinder starts moving at the same speed as a common cylinder, and slows down and stops before the end of the movement, which can prevent the product 6 to be assembled from hitting the opening and closing device too quickly, thereby causing damage to the product 6 to be assembled and the opening and closing device, and is easy to install.

[0091] Furthermore, it also includes a controller, the placement seat 23 is provided with a sensor for sensing whether there is a product to be assembled 6, the guide bar 24 is provided with a push rod three 40 and a push rod four 41 at intervals, the push rod three 40 is driven by a power device four to block and release the product to be assembled 6 located above it, and the push rod four 41 is driven by a power device five to block and release the product to be assembled 6 located above it, and the sensor, power device four and power device five are electrically connected to the controller respectively.

[0092] like Figure 5 As shown, when the sensor detects that there is no product to be assembled 6 on the placement seat 23, the push rod four 41 blocks the product to be assembled 6 located above it, and the push rod three 40 releases the product to be assembled 6 located above it, so that it falls to the placement seat 23; when the sensor detects that there is a product to be assembled 6 on the placement seat 23, the push rod three 40 blocks the product to be assembled 6 located above it, and the push rod four 41 releases the product to be assembled 6 located above it, so that the push rod four 41 above the push rod four 41 falls to above the push rod three 40.

[0093] Preferably, the sensor is an optical fiber sensor, an inductive proximity switch or a capacitive proximity switch. In this embodiment, the sensor is an optical fiber sensor.

[0094] Preferably, the action device 4 and the power device 5 are respectively a cylinder, a linear module or an electric cylinder. In this embodiment, the power device 4 is a cylinder, and the push rod 3 40 is the piston rod of the cylinder; the power device 5 is a cylinder, and the push rod 4 41 is the piston rod of the cylinder.

[0095] In order to slow down the falling speed of the product 6 to be assembled, the guide strip 24 is arranged to be inclined.

[0096] In order to prevent the product 6 to be assembled on the placement seat 23 from detaching from the placement seat 23 during movement, the placement seat 23 is provided with a placement groove 42 for placing the product 6 to be assembled, the upper end of the guide groove is connected to the product vibration plate 22, and the lower end leads to the placement groove 42, and the placement seat 23 is provided with a flat plate 43 located above the placement groove 42 and an elastic member 44 whose elastic force makes the flat plate 43 close to the upper surface of the placement seat 23.

[0097] Preferably, the second elastic member is a tension spring, a compression spring or a torsion spring. In this embodiment, the flat plate 43 is one of the plates of the hinge, the other plate of the hinge is installed on the side of the placement seat 23, and the second elastic member 44 is the torsion spring of the hinge.

[0098] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
