Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a bidirectional self-weight type stop mechanism for a fixture storage location. Background Art

[0002] The fixture warehouse is used to store fixtures. Fixtures are heavy equipment. In the past, fixture warehouses usually use one or two sets of cylinder clamps for locking. Cylinders may fail due to long-term use, such as broken shafts or stuck. Clamps are machined parts, and they may break after long-term use. All of the above may prevent the cylinder clamp mechanism from being effectively locked. The cylinder clamp and its corresponding detection switch are controlled by the PLC program. When the electrical program is disordered, misdetection or misoperation will occur. Once it falls, it will lead to high-cost maintenance and even serious consequences such as casualties. Therefore, it is urgent to design a purely mechanical and reliable locking device to solve the above problems. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] The specific embodiment of the utility model provides a two-way self-weight stop mechanism for a fixture storage position, combined with the attached Figure 1 - Attachment Figure 4As shown, it mainly includes a deadweight locking component 1 and a pushing member 2, wherein one of the deadweight locking component 1 and the pushing member 2 is arranged on the storage position 3, and the other is arranged on the transfer trolley 4. The deadweight locking component 1 has a swinging member 5, and the deadweight of the swinging member 5 can make it in a vertical state. The deadweight locking component 1 and the pushing member 2 include an intersection state and a separation state. When the deadweight locking component 1 and the pushing member 2 are in the intersection state, the pushing member 2 pushes the swinging member 5 to tilt, and the height of the highest point of the swinging member 5 is lower than or equal to the height of the track 6. At this time, the two-way deadweight stop mechanism of the fixture storage position is in When in the unlocked state, the clamp can move between the storage position 3 and the transfer trolley 4; when the self-weight locking component 1 and the pushing member 2 are in the separated state, the transfer trolley 4 moves away from the docking position of the storage position 3, and the swing member 5 is in a vertical state under the action of gravity, and the height of the swing member 5 is higher than the height of the track 6, so that the swing member 5 can limit the movement of the clamp on the storage position 3 or the transfer trolley 4. The bidirectional self-weight stop mechanism of the clamp storage position in this application is mechanically actuated by the action between the self-weight locking component 1 and the pushing member 2, does not rely on control and pneumatic drive, etc., and is safe and reliable.

[0027] Combined with Figure 1 and attached Figure 5 It is worth noting that the transfer trolley 4 and the storage location 3 of the present application both have double tracks 6. The clamp will not start to transfer until the two tracks 6 of the two are aligned at the same time. For this purpose, a self-weight locking assembly 1 and a pushing member 2 are respectively arranged at the ends of the two tracks 6 where the storage location 3 and the transfer trolley 4 intersect, and a self-pushing member 2 and a heavy locking assembly 1 are respectively arranged on the two tracks 6 where the transfer trolley 4 intersects with the storage location 3, to ensure that the self-weight locking assembly 1 is on one of the tracks 6 of the transfer trolley 4 and the storage location 3, so as to achieve its locking purpose.

[0028] In the specific embodiment of the present application, a contact portion 7 is further included. The contact portion 7 is disposed at the lower part of the swing member 5 and facing the side of the push member 2. The contact portion 7 is used to contact the push member 2. Specifically, in the present application, the contact portion 7 is designed as a rotating body. The rotating body is rotatably disposed on the swing member 5 through a horizontal axis. The contact portion 7 can roll to the top of the push member 2. The contact portion 7 can use a bearing. In this way, the friction between the contact portion 7 and the push member 2 can be smaller.

[0029] Combined with Figure 3 and attached Figure 4 As shown, the pusher 2 in the present application is provided with an eight-shaped inclined surface 8 along the moving direction of the transfer trolley 4, that is, the two inclined surfaces 8 are inclined downward and are arranged away from each other at the bottom, and when the pusher 2 intersects with the deadweight locking assembly 1, the contact portion 7 can climb along one of the inclined surfaces 8 and can descend along the other inclined surface 8. The swinging member 5 swings during the process of the contact portion 7 climbing.

[0030] In a specific embodiment of the present application, the top of the push member 2 can also be designed as a top plane 9, and two inclined surfaces 8 are respectively connected on both sides of the top plane 9, so as to form a structure similar to an isosceles trapezoid. The top plane 9 can enable the contact portion 7 to keep the swing member 5 in an inclined unlocked state within a certain range of movement of the transfer trolley 4, so that there can be a certain redundancy so that both rails 6 can be aligned.

[0031] The lowest end of the inclined surface 8 in the present application is lower than the lowest end of the contact portion 7 , and the height of the top plane 9 is lower than the rotation axis of the swing member 5 , so as to ensure that the contact portion 7 can climb along the inclined surface 8 without obstacles.

[0032] In a specific embodiment of the present application, the self-weight locking assembly 1 also includes a mounting plate 10, one side of the mounting plate 10 is connected to the storage position 3 or the transfer trolley 4, and the other side is hinged to the swing member 5. When in a separated state, the top of the swing member 5 is higher than the top of the mounting plate 10, and the self-weight locking assembly 1 is set on the storage position 3 or the transfer trolley 4 through the mounting plate 10.

[0033] It can also include a limit block 11, which is set on the mounting plate 10. A swing space 12 for the swing member 5 is left between the limit block 11 and the mounting plate 10. The setting of the limit block 11 can strengthen the load of the swing member 5 along the direction of the track 6 to prevent the clamp from pressing against the swing member 5 and damaging it.

[0034] In the present application, a sensing switch 12 can also be provided. The sensing switch 12 is provided on one side of the swing member 5, and the sensing switch 12 faces the direction of the pushing member 2, and the sensing switch 12 is provided horizontally. When the swing member 5 swings to the unlocked position, the swing member 5 can trigger the sensing switch 12, and the sensing switch 12 can transmit the state of the bidirectional self-weight stop mechanism of the fixture storage position to the control terminal of the device.

[0035] The induction switch 12 may be an infrared induction switch, and the top and bottom ends of the swing member 5 are both configured as arc ends 13, the width of the arc ends 13 is greater than the width of the swing member 5, and the wider arc ends 13 can shield the infrared induction switch and thus trigger it. The structure in which the arc ends 13 are provided at both ends can trigger the induction switch 12 in both forward and reverse swings.
