Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a positioning clamp. Background Technology

[0002] Traditional CNC machining centers typically employ a "one person, one machine" or "one person, two machines" machining mode. Operators manually position and clamp the workpiece before starting the program for machining. Manually switching between positioning and clamping modes imposes a significant workload on the operator.

[0003] To address this issue, a positioning fixture is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning fixture includes a housing, a mounting block, and a base, wherein a micro motor is mounted on the base, and a drive gear is provided at the output end of the micro motor;

[0007] The base is detachably connected to the mounting block via a housing;

[0008] The mounting block is provided with an opening to facilitate the exposure of the drive gear;

[0009] The mounting block is provided with a left clamping plate and a right clamping plate that are slidably connected thereto;

[0010] Both the left and right clamping plates mesh with the drive gear.

[0011] Furthermore, the base is provided with a connecting rod.

[0012] Furthermore, the connecting rod passes through the housing, and the mounting block is provided with a screw hole corresponding to the connecting rod. The screw hole is provided with a screw, and the connecting rod passes through the screw hole and is threadedly connected to the screw.

[0013] Furthermore, the mounting block is provided with a baffle, and a platform is provided between the baffle and the mounting block. The top and bottom ends of the mounting block are provided with grooves, and a limiting slide groove is formed between the platform and the grooves. The left clamping plate and the right clamping plate are slidably connected to the limiting slide groove.

[0014] Furthermore, the left and right clamping plates are equipped with sliding plates that cooperate with the limiting slide grooves.

[0015] Furthermore, the slide plate is provided with a rack that meshes with the drive gear.

[0016] Furthermore, the protruding portions of the left and right clamps are arranged opposite each other, and the two are not on the same horizontal plane.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model adopts a design in which a micro motor drives a clamping plate through gears and racks. The clamping plate can automatically clamp and position the product, which is convenient and quick, and greatly improves production efficiency. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of this utility model;

[0020] Figure 2 This is a schematic diagram of the internal structure of the present invention;

[0021] Figure 3 This is a schematic diagram of the mounting block structure of this utility model. Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1-3 This utility model provides a technical solution:

[0025] A positioning fixture includes a housing 1, a mounting block 2 and a base 5. For automatic clamping, a micro motor 6 is installed on the base 5 as a power source, and a drive gear 8 is provided at the output end of the micro motor 6, so that the drive gear 8 rotates.

[0026] The base 5 is detachably connected to the mounting block 2 via the housing 1, which facilitates subsequent disassembly and maintenance and makes it easier to replace parts later.

[0027] To facilitate the driving of the drive gear 8, an opening 21 is made on the mounting block 2 to allow the drive gear 8 to be exposed. At the same time, a left clamping plate 4 and a right clamping plate 3 are provided on the mounting block 2 and slidably connected thereto. In order to achieve automatic clamping of the left clamping plate 4 and the right clamping plate 3, both of them are engaged with the drive gear 8 and driven by the drive gear 8.

[0028] like Figure 2-3 As shown:

[0029] To enable disassembly, a connecting rod 7 is installed on the base 5. The connecting rod 7 passes through the housing 1. A screw hole 22 corresponding to the connecting rod 7 is opened on the mounting block 2. A screw is installed in the screw hole 22. The connecting rod 7 is inserted into the screw hole 22 and threadedly connected to the screw. The connecting rod 7 is fixed to the mounting block 2 by the screw, thus completing the assembly of the housing 1, the mounting block 2 and the base 5.

[0030] like Figure 3 As shown:

[0031] A baffle 23 is provided on the mounting block 2, and an integrally formed platform 24 is provided between the baffle 23 and the mounting block 2. Grooves 25 are provided at the top and bottom of the mounting block 2, so that a limiting slide groove is formed between the platform 24 and the groove 25. The left clamping plate 4 and the right clamping plate 3 are slidably connected to the limiting slide groove to realize the sliding function of the left clamping plate 4 and the right clamping plate 3, which is convenient for clamping. In order to facilitate sliding, a sliding plate 31 is provided on the left clamping plate 4 and the right clamping plate 3 to cooperate with the limiting slide groove. A rack 9 that meshes with the drive gear 8 is provided on the sliding plate 31.

[0032] like Figure 2-3 As shown:

[0033] In order to enable the drive gear 8 to simultaneously drive the left clamping plate 4 and the right clamping plate 3 to retract and clamp inward when rotating, the protruding parts of the two are arranged opposite each other and are not on the same horizontal plane. That is, the left clamping plate 4 is in the lower limiting groove and the right clamping plate 3 is in the upper limiting groove.

[0034] Working principle:

[0035] The micro motor 6 drives the drive gear 8 to rotate. Since the drive gear 8 meshes with the racks 9 on the left and right clamping plates respectively (the racks 9 on the left and right clamping plates are not on the same horizontal plane), when the drive gear 8 rotates, the left and right clamping plates will retract inward at the same time, thereby completing the clamping and positioning.

[0036] 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.
